They're the size of a big-city phone book, since they contain every coin issued by every country. They're split by century, one volume per century - 2000's, 1900's, 1800's and so on.
If you don't want to buy the books, you can borrow them - most larger public libraries should have copies of the 2000's and 1900's volumes at least. Online, you can subscribe to NumisMaster, a website run by the people that make the catalogues; their database is now free-access, but accessing price and mintage statistics requires a monthly fee.
Alternatively, you can post questions about the catalogue value of your coins here, and the members here will answer them for free.

Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
