Thesaurus linguae Latinae (TLL)


User Guide TLL Open Access


Thesaurus Linguae Latinae Open Access provides free access to the published volumes of the Thesaurus Linguae Latinae except the most recent three years of fascicles. The entire TLL is also available in print from De Gruyter and through the subscription-only TLL Online, which provides additional search functionality.

For help using the TLL, please see the information under User Tools. The scope, methodology, and history of the TLL is described in more detail under About the TLL. Please contact tll(at)thesaurus.badw.de for assistance or to provide feedback.

A list of downloadable and searchable PDF’s containing each volume of the TLL is provided below. The license is CC BY-NC-ND.


After opening the website (http://tll-open.badw.de/), you will see an alphabetic list of headwords (lemmata) with a search box at the top. In the list of headwords, the name of each headword is followed by a box that contains a location reference (e.g. after the headword ‘Aaron’, the numbers ‘1:41’ indicate that the headword begins in volume I, column 41 of the printed edition).

To open the article, simply click on the location reference, which will open a scanned image of the page. From here you can navigate within the article by clicking ‘Forwards’ or ‘Backwards’ to turn the page forwards or backwards. Your browser’s navigation bar will contain a permanent web address for the relevant article.

Headword Search

You can also navigate directly to an article by typing the headword (e.g. ‘ignis’) in the search box. The word ignis then appears below in the lemma list, and you can click on its location reference (‘7,1:288’) to open the first page of the entry. The search box can be cleared by pressing ‘Reset’.

You can also navigate directly to a column by typing its location into the search box. For example, entering ‘10,1:5’ returns ‘10,1:5’, ‘10,1:50’, ‘10,1:57’, ‘10,1:500’, and so on (or ‘1:41’ if there is no sub-volume). However, only columns on which an entry begins can be found in this way (e.g. ‘7,1:288’ works because it contains the start of ignis, but ‘7,1:299’ does not because it is in the middle of the entry). To reach other columns, you must first open the start of the entry and navigate from there.

The search box also enables more sophisticated headword searches. By default, a ‘simple’ search finds any headword that contains the entered string. For example, typing ‘ign’ also returns lignis, multisignis, and so on. If you select ‘word start’, searching for ‘ign’ will only return headwords that begin with ign-, such as ignis and ignispicium. By contrast, selecting ‘word end’ and searching for ‘nis’ will return abonnis, acclinis, and so on.

Regular Expressions can also be used. Check the box marked ‘RE’ (‘Regular Expressions’). A guide to the use of Regular Expressions is found here or by clicking on the box labeled ‘RE’.

Citing the TLL Open Access

There is no difference in content between the TLL Open Access and the printed TLL so it can safely be cited in the same way as the printed volumes. In addition, a permalink to the headword can be be provided by copying the address from your browser window. For more advice about citation see the FAQ.

List of lemmata

On this page you will find a list of all lemmata and sub-lemmata (indicated with 'sic') that are in Open Access, indicating the ID number as well as the volume and page number at which the respective lemma begins. You can save the page as a file by pressing Ctrl + S / Ctrl + S. This file can be opened and edited in a browser, MS Word, MS Excel, LibreOffice Writer, LibreOffice Calc, etc. This file can also be easily accessed with other programs, such as an XML parser.
