Did you know that there is a rare books collection in the Genealogy Center of the Largo Public Library? You may not because due to the fragile condition of the books, they are kept apart from the normal shelved collection. You can see them only by asking a consultant at the desk for access...and then you must wear gloves when you handle the material.
There is an index of the books in a binder on the desk in the Genealogy Center (ask a consultant for it), and the books are listed in the library catalog along with all of the other holdings.
You will find items such as "Vital Records of Sudbury, Massachusetts, "Roster of Ohio Soldiers in War with Spain," as well as some family histories like "Hathaways of America."
This is not a collection that will be useful to everyone, but you might want to check out the index at least.
