These data contain corpus concordances from a diachronic study of German nominalization patterns, reported on in Hartmann (forhc.), investigating three word-formation patterns on the basis of two corpora: a) nominalization with the suffix -ung, b) infinitival nominalization, c) verb stem conversion. For more information, see the readme file in the zip folder. First results have been published in several papers (Hartmann 2013, 2014a,b); however, these results are partly based on preliminary versions of the data archived here. Therefore, some deviations can be expected.
