Hi everyone... Would anyone like to share tips on the best ways to hear about international conferences in arts and humanities? I'd be interested in ones held by Philosophy and art departments, or topic wise about space&place, aesthetics. Interdisciplinary ones are good too. Thanks for your help!

The Institute for Historical Research is good for conference listings. It is history-led but they have international conferences on various themes.

Try Philosophy Now magazine - possibly available online?

Have you tried http://www.wooloo.org/open-call/most-recent ?
They've got a search function for seminars/forums, which sometimes throws stuff up.
