Their records from 1986 into the early 90's are also spotty. After they moved from 1010 Comm Ave to the McCormack Building, they were one floor below my office. I used to go to lunch occasionally with Hamilton Perkins, the director and another friend from my office. Several times when we went into the FRB office, Perkins showed us the mess they were dealing with. They had boxes full of blue cards, a lot of them covered with pigeon shit and nibbled by rats from being stored in the attic at Comm Ave. They probably got most of them transferred, but I know that a lot were hopeless. So don't be surprised if you discover that one of yours isn't on their list.
