We're using Zotero to present lists of the facsimile editions in the Dumbarton Oaks Research Library.  This finding aid should give you a decent idea of our holdings.  

N.B. HOLLIS (our library catalog) contains more detailed information and is always being updated. Zotero does not always import Harvard call numbers (and sometimes imports them inaccurately!), so please cross-check with HOLLIS before going to the library shelves.
