This bibliography is an attempt to include all works published before 1900 which mention Long Island, as well as later studies, up to 1979, which make a significant contribution to our knowledge. Unpublished documents have proved important sources of information, and I have included those which I have seen. No doubt there are others which have been omitted. I have cited relevant newspaper articles that I knew of but there has been no systematic examination of newspapers. Citations are as given in library cataloguing systems. For each entry a summary is given of information relating to Long Island. German language entries have been translated with the help of V.B. Meyer-Rochow and G. Stange.
