I finally got around to posting the transcription I made years ago of TgLam for my doctorate and the subsequent book. The text is from the MS Urb. 1, represented without the vocalization. There may be some new errors introduced with the copying and pasting process (and Unicode transitions) but I think I cleaned it all up. Please let me know if you find any errors.
