Musaios, a Thesaurus Linguae Graecae (TLG) and PHI CD ROM reader
Note that Musaios is shareware that can be used with limitations. For a completely free TLG / PHI reader you may like to check Diogenes.
The program has a convenient interface (no need to use the mouse all the time). Number of search matches is limited, and searches are rather slow. It copies only small amounts of text.
Musaios is currently available in a 32-bit native version for Windows. Please note that to use Musaios you must first get the Thesaurus Linguae Graecae (TLG) or / and the PHI CDs. These CD ROMs are not included in Musaios. Note also that the TLG collection is now available only on-line; the CD version is not updated any more.
