Other than Fodor's, of course? ;) Your best bet is to head to the library and look at a range of them. I'd start with Lonely Planet, as they tend to be geared more for students. Something like this would get you going.

Lonely Planet is less and less LP is geared to students on the cheap - their accommodations coverage is basically of expensive hotels and up - Let's Go Europe however is a reservoir of great info on student travel with a great rundown of hostels, youth hostels, etc.

Today's LP is not your grandfather's LP when he went to Europe decades ago.
