I'm not a lawyer, either, but I teach this stuff.
Note that the TEACH Act (the relevant part of which is codified at
17 U.S.C. 110(2)) does not provide for the conversion of analog materials to digital format, but does, as ranganathan said, allow you to show the movie to an online class. (The relevant portion in paragraph (2) begins with these words, in the lower third of the paragraph:
"display of a work in an amount comparable to that which is typically displayed in the course of a live classroom session, by or in the course of a transmission, if — " and continues until you hit paragraph (3). Also see the several paragraphs after paragraph (11) and immediately preceding Section 111.
See here for a plain-English translation of the Act's main provisions.) Also, while Section 108 explicitly allows libraries (and archives) to reproduce copyrighted works under specified circumstances, motion pictures explicitly excluded (see
17 U.S.C. 108(i), which is the last paragraph before Section 109 begins.)
However, if the film is already in digital format, you can use it without violating copyright if:
- You put it on your password-protected CMS and make it available
only to your own students.
- You make it available for streaming, rather than download.
- The plain-English guidelines I linked to says you may perform or display only "reasonable and limited portions" of a work, but the law actually allows "display of a work in an amount comparable to that which is typically displayed in the course of a live classroom session" (17 U.S.C. 110(2), assuming you meet the listed criteria (part of the class material, display is limited to students, etc.). In the statute, the "reasonable and limited portions" language is limited to performance. Showing a film is display, not performance.
Regarding fair use (which is a separate animal from the provisions of the TEACH Act):
Note that, while many libraries use "10 percent of the work" as the limit of what constitutes fair use, the law has no numerical criterion. (See the
four factors systeme_d posted above.) These four factors are all considered together. Let me give you an example. The chase scene in the 1968 movie
Bullitt became an instant classic, the chase scene to end all chase scenes. At the time
Bullitt was released, the only way to see a motion picture was to see it in the theater (usually at full price) or wait for years in hopes it would show up on broadcast TV. (There was no cable at the time, let alone Blockbuster stores or Netflix.) The chase scene generated huge buzz and was arguably the main reason many people went to see the movie. (It was not uncommon to hear people say,
"Oh, you've got to see this movie, if only for the chase scene!") The chase scene lasted only a few minutes, far less than 10 percent of the movie's total running time--but if you were to display just this scene to an audience (back in 1968, anyway), you arguably would have had a profound effect on the movie's potential market or value. It could be argued that, once the audience had seen the chase, they no longer had a compelling reason to see the movie.
Personally, I believe that showing the entire movie constitutes legal use if (a) the entire movie contributes to the lesson, (b) you limit the display to your own students, and (c) you prevent the students from making copies. (Remember, though, I'm not a lawyer, and this isn't legal advice, just my reading of the law.)
One last thing: I see no provision in the law that the original copy must be owned by the library or the instructor, per se. What the law requires is that the original be a lawfully made copy, nothing more. The library's policy is probably based on that provision and the library's fear that you might bring them a bootleg copy. I imagine that Netflix and Blockbuster (etc.) probably has a provision in their rental agreements that the borrower won't make any copies for any reason, so if you make a copy for this purpose, you've violated the contract, which means the copy is unlawful. And, of course, you can't use a pirated copy that you downloaded from somewhere. But there's no reason you can't use your cousin's copy, if you wanted to, as long as your cousin obtained the copy legally and gave you permission to borrow it for this purpose.
