First of all, settle down – the X Special Collection is NOT pornography. It’s what Milne calls its collection of (mainly) rare books, some dating back to the 16th century. It’s had several addresses in Milne over the years.
Items in the X Special Collection are cataloged, which means you can find them in Milne’s catalog, GLOCAT. Because they are part of a special collection, they can only be retrieved by a staff member during weekdays and used in the library. The best way to request X materials is to come to the Collection Management office (Milne 108). Hours and availability are listed here: https://www.geneseo.edu/library/special-collections-milne-library
