Library Information

OGSA Library

OGSA maintains an extensive collection of Ostfriesen community lineage books (Ortsippenbücher or OSBs) and other resources related to Ostfriesland families and the region in our library collection.  A partial listing of our resources has been compiled and can be found here. While some of these resources are out-of-print, others are available for purchase in our Store.

OGSA also has all of the published Ortsfamilienbücher (lineage books) for the district of Oldenburg - which OGSA has in stock and available for sale.
Our library resources are located at the Minnesota Genealogical Society (MGS) Library
