Do you do research for ancestors in Germany? If so, you probably know of (or should know of) Meyers Gazetteer (Meyers Orts- und Verkehrs-Lexikon des Deutschen Reichs), but it is a pain to decipher. Now it is online free with a great interface at Meyers (www.Meyersgaz.org). And there is no need to be able to read old German script (fractur), as the abbreviations are translated and explained. There is also a map you can enlarge to see the precise location.
My great-grandfather came from Drakenburg (isn't that neat that he came from Dragon City?). You can read the entry for Drakenburg HERE. In the lower right, the abbreviations are all explained, so I don't have to go to the beginning to the book to get that info.
