The text I am reading is what is generally known as the Alexandrian version, edited by Kurt Aland, Matthew Black, Carlo M. Martini, Bruce M. Metzger, and Allen Wikgren in cooperation with the Institute for New Testament Textual Research. The foregoing credits are taken from the title page. If you are looking for a copy, this is what it looks like. The best edition to get is the one that also has a dictionary at the back. Older copies have a flexible plastic cover which makes the volume easier to handle. Newer ones have a stiff hard cover. If you need a copy, look for it at Alibris.
