Fair Use:
The owner of the copyrighted material controls what constitutes "fair use" of their material. The U.S. Copyright Office states:
"One of the more important limitations is the doctrine of “fair use.” The doctrine of fair use has developed through a substantial number of court decisions over the years and has been codified in section 107 of the copyright law.

Section 107 contains a list of the various purposes for which the reproduction of a particular work may be considered fair, such as criticism, comment, news reporting, teaching, scholarship, and research. Section 107 also sets out four factors to be considered in determining whether or not a particular use is fair:

• The purpose and character of the use, including whether such use is of commercial nature or is for nonprofit educational purposes
• The nature of the copyrighted work
• The amount and substantiality of the portion used in relation to the copyrighted work as a whole
• The effect of the use upon the potential market for, or value of, the copyrighted work
For more information - Click here

LAUSD Bulletin 714 further explains "Fair Use" and the limitations of what constitutes the limitations of using works under "fair use" as:

  • IV. Fair Use

    Section 107 identifies four criteria for judging fair use of copyrighted works for purposes such as criticism, scholarship, research, and teaching: the purpose and character of the use, e.g., profit or nonprofit educational purposes; the nature of the copyrighted work, e.g., fiction or nonfiction; the amount and substantiality of the portion used, e.g., one sentence from a novel or eight lines from a sonnet; and, the effect of the use upon the potential market.

    To further clarify these criteria, various fair use guidelines have been formulated and approved by various publishers, producers, and educational organizations. These guidelines are not part of the Copyright Act, but do serve as indicators of acceptable, “safe harbor” usages.

    This Section has been amended to allow the four fair use criteria to be applied to the use of an unpublished work.

    V. Fair Use Guidelines for Classroom Copying: Books and Periodicals

    A. Single Copies for Teachers
    For the purposes of scholarly research, teaching, or preparation to teach a class, a teacher may make a copy (or request a copy be made) of a book chapter; periodical/newspaper article; short story, short essay, or short poem; or a chart, graph, diagram, drawing, cartoon, or picture from a book, periodical, or newspaper.

    B. Multiple Copies for Classroom Use
    Multiple copies, i.e., one copy per pupil in a class, may be made by or for the teacher presenting the course for classroom use provided that the copying meets the tests of brevity, spontaneity, and cumulative effect and includes a copyright notice.

    1. Brevity
    a. Poetry: Maximum of 250 words. This may be a complete poem if printed on one to two pages or an excerpt from a longer poem.
    b. Prose: A complete article, story, or essay of less than 2,500; an excerpt of not more than 1,000 words or 10% of the work, whichever is less. However, works combining language and illustrations, such as picture books, which fall short of 2,500 words in their entirety, may NOT be reproduced in their entirety. Personnel may copy not more than two published pages containing less than 10% of the words found in the text.

    2. Spontaneity
    a. An individual teacher requests the copying NOT the department, school, district, etc.
    b. The decision to use the work with a class and the date on which the copy is used are so close together, permission to copy would not be received in time.

    3. Cumulative effect
    a. The copied material is for only one course in the school.
    b. During a class term, only one short poem, article, story, essay, or two excerpts from the same author may be copied; no more than three from the same collective work.
    c. During a class term, no more than 9 instances of multiple copying for one course.
    d. The last two limitations above do not apply to current news periodicals, newspapers, and current news sections of other periodicals.

    4. Prohibitions
    a. No copying to create or substitute for anthologies, compilations, or collective works.
    b. No copying of consumables, e.g., workbooks, exercises, standardized tests, answer sheets.
    c. No copying to substitute for actual purchases of books, reprints, or periodicals.
    d. No copying because higher authority directed it.

ISIS is an initiative of the Los Angeles Unified School District (LAUSD) to replace 26 antiquated student information systems with a single, modern, integrated one. LAUSD will be the first school district of considerable size and complexity to centralize all student records within a secure, web-based software application.

As the nation's second largest school district, LAUSD pioneers the effort of bringing massive, disparate student records systems up to the high-tech standards of the 21st century. For the first time, a student's comprehensive and complete data will be accessible at the click of a mouse.

ISIS is composed of four student information systems:

Early Education Student Information System (EESIS),
Adult Education Student Information System (Adult SIS),
Welligent, and LAUSDMAX

ISIS works with the Decision Support System (DSS) and Student Transportation, Student Testing, and M.A.P.S. to bring critical information together under one roof.

ISIS will be the model system for the capturing and real-time tracking of information, encompassing all students, from early to adult education.
