While collecting postal librariana I have managed to acquire many examples of one of the most common forms of library communication - the overdue library materials notice. I've written previously about my large collection of overdue notices on postal cards. I've also written about the oldest overdue notice in my collection. Recently I acquired a much older overdue notice. It is shown above and it was mailed on Jan. 7, 1832 by Sir P. Dun's Library in Dublin, Ireland. The Librarian was Thomas Herbert Orpen and he courteously ends the overdue message with " I am your obedient Servant". The library was part of Sir Patrick Dun's Hospital whose building is shown at the top of the overdue notice. Sir Patrick Dun (1642-1712) was a prominent Irish physician who left an endowment in his will that resulted in the establishment the hospital in 1800. The hospital ceased operation in 1986. Dun also built an extensive personal medical library that is now part of the Royal College of Physicians Library in London which also houses the archives for the hospital.
