Kim mentioned the basement and the sets of books. I went there about six years ago and found the whole process somewhat difficult. The room was swarming with para-legals and, according to one I spoke with, crooks looking to find properties to sell that they don't own. But if you can master the system of back and forth lookups between two sets of ledger books you can find a property's history. I think the secret is trying to charm one of the clerks into giving you more than a 10 second explanation of the system. It is fun, though, to find the histories of where your ancestors lived, for how long and whether they owned or rented the houses. Bart
