Great educational website:

Students of Low Saxon (Low German) will find on these pages lists and tables of North Saxon grammatical forms and paradigms. This is an ongoing effort.
Low Saxon (Low German) was recognized as a legitimate language only recently. Prior to that, the dialects of Northern Germany were regarded as belonging to German, and the dialects of the Eastern Netherlands were regarded as belonging to Dutch. Because of centuries of official and educational neglect and suppression, the language has been unable to develop a standard dialect and a standard orthography, even though there is a notable written Low Saxon tradition.
