Books in Print used to be a book in print. Updated yearly, I used it at the library.

Wow I can only imagine how unwieldy that was to use. Was it just one big list by date published or did they did they try to order by title/author/publisher? Books in Print nowadays is tens of thousands of (mostly garbage) records monthly - I imagine the volume was a lot less back then, but still had to be a lot to sort through on paper.

Several thousand pages over a few volumes (ISBN 978-1-63700-938-3):
