Champaign Public Library and Urbana Free Library also have guidebooks available for checkout!
Guidebooks can be an excellent resource for planning a trip to Europe. Before you select a guidebook, be sure to read Rick Steves' article on Comparing Guidebooks.
Remember, recent information is the best information! Be sure to check the publication date before planning with a guide. Older guides may still be useful as references, but be sure to also verify the information in more recent sources.
