According to its website the University Club is "New York’s premier social club offering unparalleled services to members - from gracious dining, luxurious accommodations and a variety of social events, to extensive athletic facilities and the world’s largest and finest club library." The club received its charter in 1864, but its roots date back to 1861. It's current building located at West 54th Street at 5th Avenue was completed in 1899 and includes an incredibly beautiful library. The postal card above which was mailed by the library on Sept. 26, 1900 is a recent addition to my postal librariana collection. The Librarian W. H. Duncan, Jr. is responding to a request from one of the club's members. Duncan had just become librarian after serving as a branch librarian for the Brooklyn Public Library.
