I'm surprised that many don't know of it, since it's been linked to quite a bit in past threads. Perhaps we need a permanent links page to various Detroit history resources.

Google books also has the complete 2nd edition from 1914:

If this link doesn't work, search for "the book of Detroiters" using the quotation marks under google books.
