[PW] Rare Book Appraisal

[Jim Longo]

This one's for me, so no rush.  My uncle has come across a large collection of books from the 1910s and 1920s--many of them first editions, some of them signed.  He wants to know how much, if anything, he's going to be adding to my cousins' college funds.
 
Are there legitimate websites devoted to rare book appraisal, or does one have to deal directly with an appraiser?
 
Thanks in advance,
