While electronic texts are now available on the web in many languages of the world, in the case of some languages, their highly inflectional morphological structure compound the difficulties in compiling corpora. In this chapter, the author discusses the complexity of Polish morphology and the compilation of corpora including the problem of ambiguity created by the similarity of inflectional endings. From his account of the situation with respect to corpus compilation in Poland, it is also shown that corpora providing Polish language data are not as readily available as in some other languages discussed in this volume. Although data are not altogether missing in Poland, the information provided appears to be of greater interest to corpus linguists, while it is still only of limited use to practising translators.
