Miss Louise, the Library Cat, affectionately known as "Weezie," came to the Bay St. Louis-Hancock County Library in 2001 after the Hancock County Library System received the National Award for Library Service. She has lived here since that time, surviving Katrina in the library. She even had National Guardsmen ordered to make sure she had food and water while they used the library as a staging area.

Weezie has become the mascot of the library and her face has been used in national conferences for library catalog provider, SirsiDynix. She is named after the first librarian in Bay St. Louis, Miss Louise Crawford. She makes it her job to supervise the library staff to assure that they are doing the work correctly and providing great customer service.
