Section 108 of the Copyright Act allows libraries and archives, within limits, to make and distribute copies of all types of copyrighted works for preservation and security purposes.

If the work is unpublished, the library or archive may make up to three copies of the work as long as the work is currently in its collection and the copies are solely for preservation or security, or for deposit for research use at another eligible institution. If the copy is in digital format, it may not leave the institution’s physical premises.
