More Stack's Auction Sale Catalogs on NNP

Stack's auction sale catalogs are posted through 1987. This is an extensive group, numbering over 700 titles beginning in 1935. Complete sets are rare, and it is challenging even to borrow all the catalogs for scanning purposes. The Newman library contains several hundred, and we will be checking in with other libraries to help fill gaps. Currently over 300 are posted, and the scanning will continue until the set is complete!
