You’re spot on with this. I recently converted a local history book from 1911 to Markdown, ePub and HTML and tracked the changes on GitHub. Only a handful of copies of this book exist in physical form and it has been photo copied (which is great).
However, I was completely shot down by the local library when I was discussing it with them. They said they already had a photo copy and didn’t need anymore digital editions, I tried to explain the benefits of having it in a machine readable format but they wouldn’t entertain it. I completed the project for me, so I wasn’t too bothered, but thought they might have been interested in archiving it but they weren’t.
My general feeling is that they didn’t like an outsider contributing and touching on a format they didn’t know so got slightly defensive.
Find an archive and make sure they're aware of the work you've done. Archivists always love meeting people who've done good work in the space they're in. Especially when they have some tech chops which is desperately lacking in the space.
Beyond that, if the material is public domain, that library is called The Internet. Post it and promote it. The only reason to seek association with a library is if you're looking for cred for some reason, and that's not the business they're in.
If it's not public domain, or if you haven't marked your derivative work public domain, then you put a library in an awkward position. Realize that these are the types of people who still post little notes by the copy machines saying what's permissible and enjoy policing it.
Most just say no for the same reason that Hollywood returns ideas and scripts unopened. They're busy and the cost/benefit isn't there.
Although the self-described online ones tend to play fast and loose, real librarians have a formal code of ethics which is worth reviewing.
Interesting. I wonder if libraries suffer a supply-chain risk and so avoid taking contributions from (non-vetted) individuals? I imagine that over time a library gets lots of offers to take "important works of literature" from cranks, and perhaps they've developed this culture to protect them from that. Pure speculation, of course.
Libraries typically don't even accept print books or CDs/DVDs. If there's a donation bin outside it probably isn't even theirs. And if stuff actually winds up with them, it just gets sold off so they can purchase material via vetted channels.
