Frequently Asked Questions

How can we help you?

The TLG® is a research project at the University of California, Irvine. Its primary goal is to create a comprehensive digital collection that includes all extant works of Greek literature from antiquity to the present era, and to develop search mechanisms that allow scholars and students to search this collection. In order to recover some of the costs associated with this activity, the TLG charges reasonable subscription fees.

TLG Website

The TLG is available online only. From 1985 to 2000 the TLG collection was disseminated in CD ROM format. The last CD ROM (CD ROM E) was issued in 1999. The project has no plans to produce another CD ROM (or DVD) version of its corpus and is focusing its resources on online dissemination. Since 2008 the TLG® is no longer issuing or renewing CD ROM licenses.

If you wish to cite the online TLG in a bibliography, please use the URL and the month and year you accessed it, as in the following example (bibliogrqaphic formats vary): Thesaurus Linguae Graecae® Digital Library. Ed. Maria C. Pantelia. University of California, Irvine. https://stephanus.tlg.uci.edu (accessed _DATE_).

To cite a specific edition in TLG, we recommend the following:
T.W. Allen, Homeri Ilias, vols. 2-3 Oxford: Clarendon Press 1931: 2:1-356; 3:1-370, Thesaurus Linguae Graecae® Digital Library. https://stephanus.tlg.uci.edu/Iris/inst/browser.jsp#doc=tlg&aid=0012&wid=001&q=HOMERUS& (accessed _DATE_).
Please consult a style guide for more information.

The Canon of Greek Authors and Works is a searchable database of all texts present in the corpus. If you cannot find a particular text in the Canon, please contact us and we will make every effort to include it in the corpus as a priority. Digitization and text editing can take up to 9 months.

The TLG® license explicitly prohibits copying, downloading and redistribution of texts. Users may copy short passages (a fee lines) for research purposes or for use in instructional materials (handouts), but they may not download and/or redistribute larger portions or complete texts.

If you are an editor preparing a new critical edition, the TLG® may be able to provide you with a digital copy so that you do not have to retype the text. Please contact the TLG for more information.

The TLG® has set limits to the number of pages users may access. This is done primarily to prevent downloading of TLG materials. If you exceed the limit, your access may be temporarily suspended. In most cases, we restore access within minutes. If your access is not restored after a day, please contact us and we will investigate further.

The pricing schedule for online access to the TLG is based on the size of the institution and the estimated number of anticipated users (not simultaneous users). At the time of renewal, the level of usage compared to other institutions is also taken into consideration in determining the renewal price.

The TLG Project is a non-profit academic unit. We charge fees to recover our costs and we make every effort to keep the cost of institutional access as low as possible. The cost is determined based upon the size of the institution and the number of users at the institution. Prior to determining the cost of a new subscription, we ask institutions to fill out a questionnaire to give us a better idea about their anticipated use. At the time of renewal actual usage is also taken into consideration in determining the price.

Institutional subscribers to the online version may cancel at any time. An administrative fee will be applied.

Online access is provided via IP address authentication. Additionally, institutional users are asked to create a profile with a username and password to access the data. Users who connect via institutional IPs are directed to the full TLG corpus. Users connecting via non -institutional IPs are forwarded to the Abridged (Open Access) version. This is change from the original system where login for institutional users is optional.

Yes. You do need a username and password even if you are are an institutional user. You also need to authenticate via your institutional proxy or VPN in order to access the Full corpus. If you do not connect via an authorized IP, our system will direct you to the Abridged corpus. You do not need a separate account to view open access materials. Our system checks your IP and will direct you to the full or Abridged corpus depending on your credentials.Our Privacy Policy is linked to all pages.

The TLG does not have expertise in proxy configuration. Each proxy is different and settings may vary from one institution to another.

To cancel your subscription, please send us a note (email) indicating your desire to cancel. We are sorry, we cannot issue refunds for one-year subscriptions.

Yes, all institutions and individuals must return their CD ROMs when their CD ROM subscription expires and switch to online access. Please note that in accordance with the TLG® license agreement, the TLG disk remains property of the Regents of the University of California and must be returned at the end or cancellation of the subscription.

Unfortunately, we do not provide any trial usage. However, interested individuals and institutions may preview the entire Canon of Greek Authors and Works and our Abridged version, both open to the public. The Abridged version contains a smaller corpus of texts with the same search capabilities.
