Harvard Papyri Online

This is definitely worth a second mention: on Evangelical Textual Criticism, Peter Head writes:

The Houghton Library at Harvard have begun putting digital images of their papyri online (front page here). (HT PapyL also What's New in Papyrology?)
They haven't finished yet, but there are two of interest to NT scholars (and two more to come):

P10 (Rom 1.1-7; POxy 209 = Harvard MS Gr SM2218)

Gospel of Thomas (POxy 655 = Harvard MS Gr SM4367)

071 (Matt 1.21-24; 1.25-2.2; POxy 401 = Harvard MS Gr SM3735)
P9 (1 John 4.11-12, 14-17; POxy 402 = Harvard MS Gr SM3736)

It is great to have P.Oxy 655 in particular, and the quality is remarkably good.
