Database
Since 2003 the Thesaurus has been available not only in the printed version but also in electronic form: at first on CD‑ROM and now on-line, under the auspices of the publishers De Gruyter. Many research institutions provide free access to their users. The online Thesaurus includes all the fascicles which have appeared since 1900, not in the form of a simple PDF but in a version which allows the user to look at the structure of articles in depth. While it is possible to find a lemma and read through the article line by line, as in the printed version, one can also use search functions, not available in the printed version, for example to find particular quotations wherever they are in the dictionary.
