What is this children's book (and its sequel, if I recall correctly?) A girl takes an elevator in an old house/building to a floor that opens up several generations ago. She meets children from the past there. There is a scene where the narrator finds an old photograph and sees the girl in it. In this book, or possibly its sequel, there is some going back and forth in time to find buried treasure at the house in modern times. I don't remember the reading level but it may be considered a children's book or YA book. It was probably written sometime between 1960 and 1980, and I think I read it in the early 1990s.

I am looking for photos of the Cambridge, MA area taken between 1950 and 1999. I am especially interested in the commercial areas along the current Red Line route (Porter/Harvard/Central/Kendall), and the industrial areas southeast of Central Square. If you happen to know of any repositories of offline photos, that would be cool too. Thanks!
