Sec. 107. Limitations on exclusive rights: Fair use

Notwithstanding the provisions of sections 106 and 106A, the fair use of a copyrighted work, including such use by reproduction in copies or phonorecords or by any other means specified by that section, for purposes such as criticism, comment, news reporting, teaching (including multiple copies for classroom use), scholarship, or research, is not an infringement of copyright. In determining whether the use made of a work in any particular case is a fair use the factors to be considered shall include -

(1) the purpose and character of the use, including whetherksuch use is of a commercial nature or is for nonprofit educational purposes;
(2) the nature of the copyrighted work;
(3) the amount and substantiality of the portion used in relation to the copyrighted work as a whole; and
(4) the effect of the use upon the potential market for or value of the copyrighted work.

The fact that a work is unpublished shall not itself bar a finding of fair use if such finding is made upon consideration of all the above factors.

     General Background of the Problem. The judicial doctrine of fair
   use, one of the most important and well-established limitations on
   the exclusive right of copyright owners, would be given express
   statutory recognition for the first time in section 107. The claim
   that a defendant's acts constituted a fair use rather than an
   infringement has been raised as a defense in innumerable copyright
   actions over the years, and there is ample case law recognizing the
   existence of the doctrine and applying it. The examples enumerated
   at page 24 of the Register's 1961 Report, while by no means
   exhaustive, give some idea of the sort of activities the courts
   might regard as fair use under the circumstances: "quotation of
   excerpts in a review or criticism for purposes of illustration or
   comment; quotation of short passages in a scholarly or technical
   work, for illustration or clarification of the author's
   observations; use in a parody of some of the content of the work
   parodied; summary of an address or article, with brief quotations,
   in a news report; reproduction by a library of a portion of a work
   to replace part of a damaged copy; reproduction by a teacher or
   student of a small part of a work to illustrate a lesson;
   reproduction of a work in legislative or judicial proceedings or
   reports; incidental and fortuitous reproduction, in a newsreel or
   broadcast, of a work located in the scene of an event being
   reported."
     Although the courts have considered and ruled upon the fair use
   doctrine over and over again, no real definition of the concept has
   ever emerged. Indeed, since the doctrine is an equitable rule of
   reason, no generally applicable definition is possible, and each
   case raising the question must be decided on its own facts. On the
   other hand, the courts have evolved a set of criteria which, though
   in no case definitive or determinative, provide some gauge for
   balancing the equities. These criteria have been stated in various
   ways, but essentially they can all be reduced to the four standards
   which have been adopted in section 107: "(1) the purpose and
   character of the use, including whether such use is of a commercial
   nature or is for nonprofit educational purposes; (2) the nature of
   the copyrighted work; (3) the amount and substantiality of the
   portion used in relation to the copyrighted work as a whole; and
   (4) the effect of the use upon the potential market for or value of
   the copyrighted work."
     These criteria are relevant in determining whether the basic
   doctrine of fair use, as stated in the first sentence of section
   107, applies in a particular case: "Notwithstanding the provisions
   of section 106, the fair use of a copyrighted work, including such
   use by reproduction in copies or phonorecords or by any other means
   specified by that section, for purposes such as criticism, comment,
   news reporting, teaching (including multiple copies for classroom
   use), scholarship, or research, is not an infringement of
   copyright."
     The specific wording of section 107 as it now stands is the
   result of a process of accretion, resulting from the long
   controversy over the related problems of fair use and the
   reproduction (mostly by photocopying) of copyrighted material for
   educational and scholarly purposes. For example, the reference to
   fair use "by reproduction in copies or phonorecords or by any other
   means" is mainly intended to make clear that the doctrine has as
   much application to photocopying and taping as to older forms of
   use; it is not intended to give these kinds of reproduction any
   special status under the fair use provision or to sanction any
   reproduction beyond the normal and reasonable limits of fair use.
   Similarly, the newly-added reference to "multiple copies for
   classroom use" is a recognition that, under the proper
   circumstances of fairness, the doctrine can be applied to
   reproductions of multiple copies for the members of a class.
     The Committee has amended the first of the criteria to be
   considered - "the purpose and character of the use" - to state
   explicitly that this factor includes a consideration of "whether
   such use is of a commercial nature or is for non-profit educational
   purposes." This amendment is not intended to be interpreted as any
   sort of not-for-profit limitation on educational uses of
   copyrighted works. It is an express recognition that, as under the
   present law, the commercial or non-profit character of an activity,
   while not conclusive with respect to fair use, can and should be
   weighed along with other factors in fair use decisions.
     General Intention Behind the Provision. The statement of the fair
   use doctrine in section 107 offers some guidance to users in
   determining when the principles of the doctrine apply. However, the
   endless variety of situations and combinations of circumstances
   that can rise in particular cases precludes the formulation of
   exact rules in the statute. The bill endorses the purpose and
   general scope of the judicial doctrine of fair use, but there is no
   disposition to freeze the doctrine in the statute, especially
   during a period of rapid technological change. Beyond a very broad
   statutory explanation of what fair use is and some of the criteria
   applicable to it, the courts must be free to adapt the doctrine to
   particular situations on a case-by-case basis. Section 107 is
   intended to restate the present judicial doctrine of fair use, not
   to change, narrow, or enlarge it in any way.
     Intention as to Classroom Reproduction. Although the works and
   uses to which the doctrine of fair use is applicable are as broad
   as the copyright law itself, most of the discussion of section 107
   has centered around questions of classroom reproduction,
   particularly photocopying. The arguments on the question are
   summarized at pp. 30-31 of this Committee's 1967 report (H.R. Rep.
   No. 83, 90th Cong., 1st Sess.), and have not changed materially in
   the intervening years.
     The Committee also adheres to its earlier conclusion, that "a
   specific exemption freeing certain reproductions of copyrighted
   works for educational and scholarly purposes from copyright control
   is not justified." At the same time the Committee recognizes, as it
   did in 1967, that there is a "need for greater certainty and
   protection for teachers." In an effort to meet this need the
   Committee has not only adopted further amendments to section 107,
   but has also amended section 504(c) to provide innocent teachers
   and other non-profit users of copyrighted material with broad
   insulation against unwarranted liability for infringement. The
   latter amendments are discussed below in connection with Chapter 5
   of the bill [Sec. 501 et seq. of this title].
     In 1967 the Committee also sought to approach this problem by
   including, in its report, a very thorough discussion of "the
   considerations lying behind the four criteria listed in the amended
   section 107, in the context of typical classroom situations arising
   today." This discussion appeared on pp. 32-35 of the 1967 report,
   and with some changes has been retained in the Senate report on S.
   22 (S. Rep. No. 94-473, pp. 63-65). The Committee has reviewed this
   discussion, and considers that it still has value as an analysis of
   various aspects of the problem.
     At the Judiciary Subcommittee hearings in June 1975, Chairman
   Kastenmeier and other members urged the parties to meet together
   independently in an effort to achieve a meeting of the minds as to
   permissible educational uses of copyrighted material. The response
   to these suggestions was positive, and a number of meetings of
   three groups, dealing respectively with classroom reproduction of
   printed material, music, and audio-visual material, were held
   beginning in September 1975.
     In a joint letter to Chairman Kastenmeier, dated March 19, 1976,
   the representatives of the Ad Hoc Committee of Educational
   Institutions and Organizations on Copyright Law Revision, and of
   the Authors League of America, Inc., and the Association of
   American Publishers, Inc., stated:
       You may remember that in our letter of March 8, 1976 we told
     you that the negotiating teams representing authors and
     publishers and the Ad Hoc Group had reached tentative agreement
     on guidelines to insert in the Committee Report covering
     educational copying from books and periodicals under Section 107
     of H.R. 2223 and S. 22 [this section], and that as part of that
     tentative agreement each side would accept the amendments to
     Sections 107 and 504 [this section and section 504 of this title]
     which were adopted by your Subcommittee on March 3, 1976.
       We are now happy to tell you that the agreement has been
     approved by the principals and we enclose a copy herewith. We had
     originally intended to translate the agreement into language
     suitable for inclusion in the legislative report dealing with
     Section 107 [this section], but we have since been advised by
     committee staff that this will not be necessary.
       As stated above, the agreement refers only to copying from
     books and periodicals, and it is not intended to apply to musical
     or audiovisual works.
     The full text of the agreement is as follows:
     AGREEMENT ON GUIDELINES FOR CLASSROOM COPYING IN NOT-FOR-PROFIT
                        EDUCATIONAL INSTITUTIONS
                  WITH RESPECT TO BOOKS AND PERIODICALS               
       The purpose of the following guidelines is to state the minimum
     and not the maximum standards of educational fair use under
     Section 107 of H.R. 2223 [this section]. The parties agree that
     the conditions determining the extent of permissible copying for
     educational purposes may change in the future; that certain types
     of copying permitted under these guidelines may not be
     permissible in the future; and conversely that in the future
     other types of copying not permitted under these guidelines may
     be permissible under revised guidelines.
       Moreover, the following statement of guidelines is not intended
     to limit the types of copying permitted under the standards of
     fair use under judicial decision and which are stated in Section
     107 of the Copyright Revision Bill [this section]. There may be
     instances in which copying which does not fall within the
     guidelines stated below may nonetheless be permitted under the
     criteria of fair use.
                               GUIDELINES                            
     I. Single Copying for Teachers
       A single copy may be made of any of the following by or for a
     teacher at his or her individual request for his or her scholarly
     research or use in teaching or preparation to teach a class:
       A. A chapter from a book;
       B. An article from a periodical or newspaper;
       C. A short story, short essay or short poem, whether or not
     from a collective work;
       D. A chart, graph, diagram, drawing, cartoon or picture from a
     book, periodical, or newspaper;
     II. Multiple Copies for Classroom Use
       Multiple copies (not to exceed in any event more than one copy
     per pupil in a course) may be made by or for the teacher giving
     the course for classroom use or discussion; provided that:
       A. The copying meets the tests of brevity and spontaneity as
     defined below; and,
       B. Meets the cumulative effect test as defined below; and
       C. Each copy includes a notice of copyright.
     Definitions
         Brevity
       (i) Poetry: (a) A complete poem if less than 250 words and if
     printed on not more than two pages or, (b) from a longer poem, an
     excerpt of not more than 250 words.
       (ii) Prose: (a) Either a complete article, story or essay of
     less than 2,500 words, or (b) an excerpt from any prose work of
     not more than 1,000 words or 10% of the work, whichever is less,
     but in any event a minimum of 500 words.
       [Each of the numerical limits stated in "i" and "ii" above may
     be expanded to permit the completion of an unfinished line of a
     poem or of an unfinished prose paragraph.]
       (iii) Illustration: One chart, graph, diagram, drawing, cartoon
     or picture per book or per periodical issue.
       (iv) "Special" works: Certain works in poetry, prose or in
     "poetic prose" which often combine language with illustrations
     and which are intended sometimes for children and at other times
     for a more general audience fall short of 2,500 words in their
     entirety. Paragraph "ii" above notwithstanding such "special
     works" may not be reproduced in their entirety; however, an
     excerpt comprising not more than two of the published pages of
     such special work and containing not more than 10% of the words
     found in the text thereof, may be reproduced.
         Spontaneity
       (i) The copying is at the instance and inspiration of the
     individual teacher, and
       (ii) The inspiration and decision to use the work and the
     moment of its use for maximum teaching effectiveness are so close
     in time that it would be unreasonable to expect a timely reply to
     a request for permission.
         Cumulative Effect
       (i) The copying of the material is for only one course in the
     school in which the copies are made.
       (ii) Not more than one short poem, article, story, essay or two
     excerpts may be copied from the same author, nor more than three
     from the same collective work or periodical volume during one
     class term.
       (iii) There shall not be more than nine instances of such
     multiple copying for one course during one class term.
       [The limitations stated in "ii" and "iii" above shall not apply
     to current news periodicals and newspapers and current news
     sections of other periodicals.]
     III. Prohibitions as to I and II Above
       Notwithstanding any of the above, the following shall be
     prohibited:
       (A) Copying shall not be used to create or to replace or
     substitute for anthologies, compilations or collective works.
     Such replacement or substitution may occur whether copies of
     various works or excerpts therefrom are accumulated or reproduced
     and used separately.
       (B) There shall be no copying of or from works intended to be
     "consumable" in the course of study or of teaching. These include
     workbooks, exercises, standardized tests and test booklets and
     answer sheets and like consumable material.
       (C) Copying shall not:
         (a) substitute for the purchase of books, publishers'
       reprints or periodicals;
         (b) be directed by higher authority;
         (c) be repeated with respect to the same item by the same
       teacher from term to term.
       (D) No charge shall be made to the student beyond the actual
     cost of the photocopying.
       Agreed March 19, 1976.

                                              By Alexander C. Hoffman. 
                                         Chairman, Copyright Committee.
     In a joint letter dated April 30, 1976, representatives of the
   Music Publishers' Association of the United States, Inc., the
   National Music Publishers' Association, Inc., the Music Teachers
   National Association, the Music Educators National Conference, the
   National Association of Schools of Music, and the Ad Hoc Committee
   on Copyright Law Revision, wrote to Chairman Kastenmeier as
   follows:
       During the hearings on H.R. 2223 in June 1975, you and several
     of your subcommittee members suggested that concerned groups
     should work together in developing guidelines which would be
     helpful to clarify Section 107 of the bill [this section].
       Representatives of music educators and music publishers delayed
     their meetings until guidelines had been developed relative to
     books and periodicals. Shortly after that work was completed and
     those guidelines were forwarded to your subcommittee,
     representatives of the undersigned music organizations met
     together with representatives of the Ad Hoc Committee on
     Copyright Law Revision to draft guidelines relative to music.
       We are very pleased to inform you that the discussions thus
     have been fruitful on the guidelines which have been developed.
     Since private music teachers are an important factor in music
     education, due consideration has been given to the concerns of
     that group.
       We trust that this will be helpful in the report on the bill to
     clarify Fair Use as it applies to music.
     The text of the guidelines accompanying this letter is as
   follows:
                GUIDELINES FOR EDUCATIONAL USES OF MUSIC             
       The purpose of the following guidelines is to state the minimum
     and not the maximum standards of educational fair use under
     Section 107 of H.R. 2223 [this section]. The parties agree that
     the conditions determining the extent of permissible copying for
     educational purposes may change in the future; that certain types
     of copying permitted under these guidelines may not be
     permissible in the future, and conversely that in the future
     other types of copying not permitted under these guidelines may
     be permissible under revised guidelines.
       Moreover, the following statement of guidelines is not intended
     to limit the types of copying permitted under the standards of
     fair use under judicial decision and which are stated in Section
     107 of the Copyright Revision Bill [this section]. There may be
     instances in which copying which does not fall within the
     guidelines stated below may nonetheless be permitted under the
     criteria of fair use.
     A. Permissible Uses
       1. Emergency copying to replace purchased copies which for any
     reason are not available for an imminent performance provided
     purchased replacement copies shall be substituted in due course.
       2. (a) For academic purposes other than performance, multiple
     copies of excerpts of works may be made, provided that the
     excerpts do not comprise a part of the whole which would
     constitute a performable unit such as a section, movement or
     aria, but in no case more than 10% of the whole work. The number
     of copies shall not exceed one copy per pupil.
       (b) For academic purposes other than performance, a single copy
     of an entire performable unit (section, movement, aria, etc.)
     that is, (1) confirmed by the copyright proprietor to be out of
     print or (2) unavailable except in a larger work, may be made by
     or for a teacher solely for the purpose of his or her scholarly
     research or in preparation to teach a class.
       3. Printed copies which have been purchased may be edited or
     simplified provided that the fundamental character of the work is
     not distorted or the lyrics, if any, altered or lyrics added if
     none exist.
       4. A single copy of recordings of performances by students may
     be made for evaluation or rehearsal purposes and may be retained
     by the educational institution or individual teacher.
       5. A single copy of a sound recording (such as a tape, disc or
     cassette) of copyrighted music may be made from sound recordings
     owned by an educational institution or an individual teacher for
     the purpose of constructing aural exercises or examinations and
     may be retained by the educational institution or individual
     teacher. (This pertains only to the copyright of the music itself
     and not to any copyright which may exist in the sound recording.)
     B. Prohibitions
       1. Copying to create or replace or substitute for anthologies,
     compilations or collective works.
       2. Copying of or from works intended to be "consumable" in the
     course of study or of teaching such as workbooks, exercises,
     standardized tests and answer sheets and like material.
       3. Copying for the purpose of performance, except as in A(1)
     above.
       4. Copying for the purpose of substituting for the purchase of
     music, except as in A(1) and A(2) above.
       5. Copying without inclusion of the copyright notice which
     appears on the printed copy.
     The problem of off-the-air taping for nonprofit classroom use of
   copyrighted audiovisual works incorporated in radio and television
   broadcasts has proved to be difficult to resolve. The Committee
   believes that the fair use doctrine has some limited application in
   this area, but it appears that the development of detailed
   guidelines will require a more thorough exploration than has so far
   been possible of the needs and problems of a number of different
   interests affected, and of the various legal problems presented.
   Nothing in section 107 or elsewhere in the bill is intended to
   change or prejudge the law on the point. On the other hand, the
   Committee is sensitive to the importance of the problem, and urges
   the representatives of the various interests, if possible under the
   leadership of the Register of Copyrights, to continue their
   discussions actively and in a constructive spirit. If it would be
   helpful to a solution, the Committee is receptive to undertaking
   further consideration of the problem in a future Congress.
     The Committee appreciates and commends the efforts and the
   cooperative and reasonable spirit of the parties who achieved the
   agreed guidelines on books and periodicals and on music.
   Representatives of the American Association of University
   Professors and of the Association of American Law Schools have
   written to the Committee strongly criticizing the guidelines,
   particularly with respect to multiple copying, as being too
   restrictive with respect to classroom situations at the university
   and graduate level. However, the Committee notes that the Ad Hoc
   group did include representatives of higher education, that the
   stated "purpose of the * * * guidelines is to state the minimum and
   not the maximum standards of educational fair use" and that the
   agreement acknowledges "there may be instances in which copying
   which does not fall within the guidelines * * * may nonetheless be
   permitted under the criteria of fair use."
     The Committee believes the guidelines are a reasonable
   interpretation of the minimum standards of fair use. Teachers will
   know that copying within the guidelines is fair use. Thus, the
   guidelines serve the purpose of fulfilling the need for greater
   certainty and protection for teachers. The Committee expresses the
   hope that if there are areas where standards other than these
   guidelines may be appropriate, the parties will continue their
   efforts to provide additional specific guidelines in the same
   spirit of good will and give and take that has marked the
   discussion of this subject in recent months.
     Reproduction and Uses for Other Purposes. The concentrated
   attention given the fair use provision in the context of classroom
   teaching activities should not obscure its application in other
   areas. It must be emphasized again that the same general standards
   of fair use are applicable to all kinds of uses of copyrighted
   material, although the relative weight to be given them will differ
   from case to case.
     The fair use doctrine would be relevant to the use of excerpts
   from copyrighted works in educational broadcasting activities not
   exempted under section 110(2) or 112, and not covered by the
   licensing provisions of section 118. In these cases the factors to
   be weighed in applying the criteria of this section would include
   whether the performers, producers, directors, and others
   responsible for the broadcast were paid, the size and nature of the
   audience, the size and number of excerpts taken and, in the case of
   recordings made for broadcast, the number of copies reproduced and
   the extent of their reuse or exchange. The availability of the fair
   use doctrine to educational broadcasters would be narrowly
   circumscribed in the case of motion pictures and other audiovisual
   works, but under appropriate circumstances it could apply to the
   nonsequential showing of an individual still or slide, or to the
   performance of a short excerpt from a motion picture for criticism
   or comment.
     Another special instance illustrating the application of the fair
   use doctrine pertains to the making of copies or phonorecords of
   works in the special forms needed for the use of blind persons.
   These special forms, such as copies in Braille and phonorecords of
   oral readings (talking books), are not usually made by the
   publishers for commercial distribution. For the most part, such
   copies and phonorecords are made by the Library of Congress'
   Division for the Blind and Physically Handicapped with permission
   obtained from the copyright owners, and are circulated to blind
   persons through regional libraries covering the nation. In
   addition, such copies and phonorecords are made locally by
   individual volunteers for the use of blind persons in their
   communities, and the Library of Congress conducts a program for
   training such volunteers. While the making of multiple copies or
   phonorecords of a work for general circulation requires the
   permission of the copyright owner, a problem addressed in section
   710 of the bill, the making of a single copy or phonorecord by an
   individual as a free service for blind persons would properly be
   considered a fair use under section 107.
     A problem of particular urgency is that of preserving for
   posterity prints of motion pictures made before 1942. Aside from
   the deplorable fact that in a great many cases the only existing
   copy of a film has been deliberately destroyed, those that remain
   are in immediate danger of disintegration; they were printed on
   film stock with a nitrate base that will inevitably decompose in
   time. The efforts of the Library of Congress, the American Film
   Institute, and other organizations to rescue and preserve this
   irreplaceable contribution to our cultural life are to be
   applauded, and the making of duplicate copies for purposes of
   archival preservation certainly falls within the scope of "fair
   use."
     When a copyrighted work contains unfair, inaccurate, or
   derogatory information concerning an individual or institution, the
   individual or institution may copy and reproduce such parts of the
   work as are necessary to permit understandable comment on the
   statements made in the work.
     The Committee has considered the question of publication, in
   Congressional hearings and documents, of copyrighted material.
   Where the length of the work or excerpt published and the number of
   copies authorized are reasonable under the circumstances, and the
   work itself is directly relevant to a matter of legitimate
   legislative concern, the Committee believes that the publication
   would constitute fair use.
     During the consideration of the revision bill in the 94th
   Congress it was proposed that independent newsletters, as
   distinguished from house organs and publicity or advertising
   publications, be given separate treatment. It is argued that
   newsletters are particularly vulnerable to mass photocopying, and
   that most newsletters have fairly modest circulations. Whether the
   copying of portions of a newsletter is an act of infringement or a
   fair use will necessarily turn on the facts of the individual case.
   However, as a general principle, it seems clear that the scope of
   the fair use doctrine should be considerably narrower in the case
   of newsletters than in that of either mass-circulation periodicals
   or scientific journals. The commercial nature of the user is a
   significant factor in such cases: Copying by a profit-making user
   of even a small portion of a newsletter may have a significant
   impact on the commercial market for the work.
     The Committee has examined the use of excerpts from copyrighted
   works in the art work of calligraphers. The committee believes that
   a single copy reproduction of an excerpt from a copyrighted work by
   a calligrapher for a single client does not represent an
   infringement of copyright. Likewise, a single reproduction of
   excerpts from a copyrighted work by a student calligrapher or
   teacher in a learning situation would be a fair use of the
   copyrighted work.
     The Register of Copyrights has recommended that the committee
   report describe the relationship between this section and the
   provisions of section 108 relating to reproduction by libraries and
   archives. The doctrine of fair use applies to library photocopying,
   and nothing contained in section 108 "in any way affects the right
   of fair use." No provision of section 108 is intended to take away
   any rights existing under the fair use doctrine. To the contrary,
   section 108 authorizes certain photocopying practices which may not
   qualify as a fair use.
     The criteria of fair use are necessarily set forth in general
   terms. In the application of the criteria of fair use to specific
   photocopying practices of libraries, it is the intent of this
   legislation to provide an appropriate balancing of the rights of
   creators, and the needs of users.
