You could get the spine cut off at a book binder place.
Interesting point. The problem would have been that I would have had to take hundreds of books to the bookbinder place and then bring them back in pieces, to say nothing of the costs. Still it's idea to keep in mind.
I just bought one of those turntables with a USB port. It didn't come with any softyware (because of copyright issues) but pointed me at public domain software (I don't remeber the name offhand) That worked well. I then recorded every LP and using the software I attempted to smooth out some of the pops and crackle sometimes wityh more success than others.
It was quite an experience listening to every cut of music that I had, and reflecting on quite how bad some of it was. Also brought back memories and there were even cuts I don't ever remember hearing before.
"This was after I had converted all my 60s/70s music on LPs to MP3 files, but that is a story for another day", I hope that day come soon I am planning to do the same with my father's collection, so could be nice have some ideas.
Have you consider to put a torrent of this collection?, with the size of the hard drives and the speed of inernet this days probably some people will like to share this collection.
I am glad that some people take the time and effort to preserve this kind of info, thank you.
You could get the spine cut off at a book binder place. In getting my thesis bound, they first glued on the spine, then used a saw to make all the edges of the pages be perfectly aligned. It was purpose made for books, so there were no ragged edges left.
