Some well-formated Selections from the Lenten Triodion posted by St. Columba Press.
A complete & downloadable version (that needs formatting) is a copy put by the Community of the Holy Myrrbearers.
The texts are also available via ftp, from FTP.EARLHAM.EDU, in the DOS directory, as TRIODION.ZIP, and TRIODION.EXE (sorry, not accessible via Mosaic).
Here is some information on how this came to be (the README file).
