I have fond memories of looking up X, and going to the library and exploring the section where X was stored, along with all the books around it. this experience is dead now with their new "system". It's been about 20 years and I'm an old dog now with limited energy. but I would love to (if I were a political activist) do an expose story about how many books were checked out before this transfer was made vs after. I strongly suspect that a lot of knowledge was lost, just due to the friction of having to know which exact book you want, vs having the liberty to browse and freely select whatever you stumbled upon. and not all the info is online, now. due to licensing and copyright. Google Books tried to fight that, but lost. It's sad.
