The Boston Public Library (BPL) has some excellent resources. Any Massachusetts resident or student is eligible for a BPL card or an eCard. Use either card to access BPL's electronic resources in Genealogy. Be sure to look at:
The New England Historic Genealogical Society is packed with great research materials, and the website (which you can access with your membership number) is really easy to navigate. The NEHGS has Ancestry.com, because of licensing restrictions, you have to use it on-site. The NEHGS is open Tuesdays (10-5), Wednesdays (10-9) Thursdays (10-5), Fridays (10-5), and Saturdays (9-5), but check the NEHGS website for current hours.
Boston Library Consortium (Requires BLC Card)
Current UMB faculty, staff and students, whose library records are in good standing, are eligible for a BLC card. The BLC card allows you to borrow materials from the libraries in the Boston Library Consortium when you physically visit those libraries. Check with individual college and universities libraries for borrowing policies.
Fenway Library Organization (Requires UMB ID)
Students, faculty, and staff must present a valid UMB ID card to borrow from FLC libraries. Check with individual college and universities libraries for borrowing policies.
Massachusetts Libraries in Public Higher Education (Requires UMB ID)
Direct borrowing privileges at most Massachusetts state college libraries are extended to current UMB faculty, staff, and students. You will need to have a current UMB ID.
UMB students using any consortia libraries are subject to the same regulations and restrictions that apply to students who attend that institution.
