What library resources do you find most useful for teaching and doing research in philosophy?
The question was sent in by a philosophy professor looking for suggestions for worthwhile purchases and subscriptions for his university’s library.
The library at the (small, public, 4-year) university where I teach already subscribes to the Philosopher’s Index, which used to be, and maybe still is, the single most valuable database for philosophers. But I’m curious to know whether there are any other services out there now I should be asking my librarian to subscribe to, either in addition to or instead of the PI. I know there are a lot of great free resources online (SEP, PhilPapers, etc), and I’m not averse to learning about others. But my question is mainly about tools requiring a paid license or subscription.
Your suggestions are welcome.
