2. How much is my book worth?

Although the CAC staff cannot appraise books, we can suggest places to search to find out the monetary value of your books (see Question 3, below). Many factors influence the value of a book, but condition is the most important of these. Local interest also affects the market value of a book, so the same book offered for sale on the east coast may not bring the same price if offered for sale in the midwest.

On the other hand, books which do not have a high monetary value can still be extremely useful to researchers, and collections of books and papers which individually would have little monetary value, can, when taken together, form a very worthwhile resource for scholars.
