I encountered a situation in which a patron wanted to share an article that I sent to [a not-for-profit organization’s] educational portal. As it happened, she had a very specific intended audience…which I thought fell within the "Fair Use" doctrine as, in addition to the information being educational, it was to be shared with [only] a small group.
This is a great question, as it occupies the crossroads of the specific exceptions for libraries and archives in the copyright code, the elements of fair use, and an essential aspect of a library’s mission: dissemination of information. So, I am a bit sorry to say the answer is most likely: NO.
