Primary Texts in English Translation
Nearly all the primary sources for the East Frankish and then German kingdoms contain some information about encounters, usually military, between Germans and the Slavs living near, along, or beyond the Elbe. Many of these have been translated into English, with helpful annotations and introductions.
Listed chronologically according to the time of their composition, those of most direct relevance to Germans and Slavs around the Elbe and beyond include:
