About the Union Catalog
The Union Catalog gives access to a listing of items held by member Libraries of the Putnam Northern Westchester SLS. Holdings are added on an ongoing basis. (This a not yet a complete record of the current member holdings.)
If you do not find a work it may be held by some library, but not yet added -- consult individual libraries also.
If you do find a needed item, contact the library who's name in on the holding to initiate an inter-library-loan
