the library industry should have embraced open source in the 90s but they just never "got it". they seem to think they just need to be involved in some hyper expensive vendor projects and somehow that will bring them validation.
i worked in this tiny library with a few ten thousands books and they were paying for system that used oracle as the Database. so basically they were paying for oracle. this was 20 years ago.
then there is JSTOR and the whole Aaron Swartz thing. JSTOR acted really inappropriately
like i feel really bad about what has happened to libraries over the past 20 years, with funding cut to the bone. but they kind of did it to themselves by thinking that "serving the public" means shoveling the publics money to proprietary vendors for no apparent reason. like OCLC has no right to take information generated by public institutions that are almost entirely funded by local taxpayers and somehow claim ownership of that information, and act like a monopolistic for profit corporation.
there are a lot of very innovating library people doing stuff like maker spaces and kids education despite all the hardships but.... this revolution has not made it to the 'library industry'.
