The Thesaurus Linguae Graecae at University of California, Irvine
The Thesaurus Linguae Graecae research project makes available, on-line, Greek literary texts from both the classical and Byzantine periods. Access to these texts is limited to subscribers. If you are using a computer in a university library, you may be able to access the TLG database by clicking here. Strabo is author # 0099 in the Canon of Greek authors and works maintained by the TLG. The Greek text of the Geography provided by the TLG is based on the edition of August Meineke (1852-53); links are provided to English translations of the Geography through Perseus.
The TLG does provide non-subscribers with limited access to a certain number of authors, but Strabo is not among them.

The Perseus Classics Collection at Tufts University
Perseus provides classical texts online, in the original Greek or Latin and in English translation. As far as Strabo’s Geography goes, the following is available online through Perseus:

• The Greek text of Strabo’s Geography, based on an 1877 reprint of Meineke (1852-53). Note that the Greek text provided through Perseus is restricted to Books 6-14 of the Geography, rather than being the full complement of seventeen books.
• An English translation of Strabo’s Geography, based on the translation by H.L. Jones which accompanied his 1917-32 edition of the Geography. Note that the English translation by Jones is only partially (Books 6-14) available through Perseus.
• The English translation of Strabo’s Geography by Hamilton and Falconer (1903-1906). All seventeen books of the Hamilton and Falconer translation are available through Perseus. Note that the Hamilton and Falconer translation is older, and the style even more dated, than Jones (1917-32).

LacusCurtius • A Gateway to Ancient Rome
This website, maintained by Bill Thayer, includes the English translation of Strabo’s Geography by H.L. Jones (1917-32), but not Jones’ edition of the Greek text (on the grounds that the Greek text of the Geography is available through the TLG). All seventeen books of Jones’ English translation of the Geography will ultimately be available through LacusCurtius. As of November 2007, Books 1-10 and 15-17 have so far been made available.
