Old English texts thus amount to a major part of the oldest sources cited in the DRW. The DRW has made arrangements, which have to be met, in order for compounds and simplexes to be featured in the articles. Compounds should not exceed the turn of the 18th century. In order for a simplex to be included in the dictionary, the word's first verifiable evidence must date from 1815, at the latest. Terms originating from the designated timeframe of 1815 to 1835 will not be printed, but published with short reference in the online version. English sources In particular, Liebermann’s aforementioned Die Gesetze der Angelsachsen (The Anglo-Saxons‘ Law) serve as an important source for the DRW with regard to Old English. Die Gesetze der Angelsachsen contains the laws proclaimed by Anglo-Saxon rulers over the course of 5 centuries and remains “authoritative” and “unsurpassed” in the field. When it comes to Old English, cross references are at times given to the seminal Anglo-Saxon Dictionary by Bosworth and Toller. In addition, many legal documents concerning the Hanseatic League and their Stahlhof (Steelyard) in London might bear special interest for the English user. Following migration to North America in the 17th and 18th century, German settlers from the Rhine Franconian language region preserved their dialects nowadays known as Pennsylvania German languages. Pennsylvania German words, thus also find their way into the DRW, e.g. freiheitsbâm > Freiheitsbaum (tree of freedom) according to Lambert’s Dictionary of the non-English words of the Pennsylvania-German dialect meaning black poplar.
