The paper reviews the present state of the diachronic part of the Czech National Corpus, with the focus on the two-million-word unannotated pivotal corpus Diakorp and its limitations in relation to corpus-based research into the history of Czech. A minimum 1,000,000-token growth, lemmatization and morphological tagging are cited as near-future enhancements to the corpus. A series of thoroughly structured monitoring diachronic corpora to be built from 2017 on is considered as a future basis for research into long-term trends in the history of Czech, thus complementing the quantity-oriented Diakorp.
