Thank you for this notice, Cheryl!. I purchased this directory about 4 years ago when I was at the NEHGS in Boston. I felt lucky to get my 10% discount as a member! To get 20% off is a real boon and well worth the money for anyone working on PGM activities! Please also keep in mind the number of organizations that are also hurting financially from the pandemic. We don't want to lose these essential archives of history and genealogy.
