Frequently asked questions

What makes a book rare?

Few surviving copies plus real demand. An early printing of a much-wanted book, in good condition, is rare in the collector's sense. Age alone is not enough.

Can Bibliocity value or buy my book?

No. We do not appraise, buy or sell books. Our guides show you how to check a book yourself and when to ask a specialist dealer or auction house.

Where should a beginner start?

Read how much is my old book worth, then try the free checklist. Both take only a few minutes.
