I haven't visited yet, but I'm very curious:

Can customers come in and use the Berk numismatic library for research/to check references?

Is it located at the main shop? (I've heard the HJB Lib. has an official relationship with the U of Chicago or UIC Library.)

BTW, I'm a couple hours south in Champaign (halfway to the Newman Numismatic Library in St Louis!).... I don't know if you ever studied at UIUC (I know Harlan & Shanna did), but the university museum collection here includes a bunch of coins donated by HJB. The UIUC Library is also pretty good on ancient coins, so I've wondered if HJB donated some duplicates at some point.

In any case, I love the idea of coin dealers using their library as a community resource and would certainly like to look up some references if possible!

(I've got other Q's but will wait my turn!)
