Even copying of a significant portion (in terms of either quantity or quality) of a copyrighted work ordinarily will fail to constitute noninfringing fair use.

Reproductions of portions of a copyrighted work that are substantial either in terms of quantity or quality will suffice.

The copyright law contains a general exception to the exclusive right of a copyright owner to publicly perform his or her copyrighted work.

Only the copyright owner has the right to reproduce a copyrighted work by making copies.

However, the copyright law permits the owner of lawful copy of a copyrighted work to display the work publicly.
