Lexington, Middlesex Co., Massachusetts
The library has three rooms containing genealogical information. The room above (and below) is always locked and you need to speak to the Reference Librarian about using them. About ten years ago, you could just walk in, but not now. The yellow room is open and is often used for research or studying. It also houses old yearbooks, including the 3 that I am in. The third room was being used for a meeting, therefore, I didn't take photos.
