Over sized/Over folio as their own Collection

Recently whenever I receive a search for an over sized/over folio book or even while I'm searching the stacks for something completely different, I stumble upon in the over sized collection an over sized book that doesn't even belong on that floor.

It's always hard already because no one seems to know what the FF or F means in front of the call number or the difference between the two.  When I first began as the search coordinator, all I ever usually had to worry about in regard to the over sized/over folio collection was that they usually were miss-shelved in both sections (F meaning the books are so large or sometimes rare they need to lay on their sides and FF meaning the book is a bit bigger than the regular books and require larger shelving), or they sometimes ended up in with the regular books.  This miss-shelving of the FF's usually occur with the art and photography books because they have the most.

However, now it seems as if they are treated as their own collection spread among different floors.  I have found ff PQ's with the ff PR's and I even found an ff Z mixed with the ff C's.  Therefore, if you are ever searching for an over sized/over folio book, make sure you are looking at every book that is in the over sized and over folio on that floor, where it would be shelved with the "regular" sized books, and possibly with the over sized books on other floors too.

Happy Searching!
