I noticed with growing anticipation last week that a NEW ART BOOKSTORE was opening on via dei Servi (no. 52/54r). Libreria de’Servi is big, modern, and specialized in… art, literature, and history books!! I went in to check it out and wish the folks good luck — hey, not to be negative, but opening a bookstore when we’re all going digital AND in an economic crisis?? They carry lots of rare, out of print editions and have their entire catalogue online. I did a search for books about engravings and turned up an impressive list. Looks like the perfect stop for your rare art book needs.
