Q. Special Borrower's card and online database access?

Your Frances Loeb Library Special Borrower's card does not include access to Harvard's licensed electronic databases. Access to the Avery Index and other electronic databases and journals is limited to current students, faculty, staff, or onsite access from a computer within one of the Harvard libraries. 

However, you might try the Architectural Publications Index. This catalogue is an index to articles in over 300 architectural periodicals, as well as a listing of books and audio visual materials acquired by the RIBA Library.
