OT: Interesting easy-read on papyri classifying with pics
Since Logos now is just 'chock-full' of papyri (to the progressive consternation of Perseus downloaders), you might want to quickly read Tim Finney's page: http://www.tfinney.net/Hands/index.html I find his transparency very refreshing.
I ran into him from Mark Hoffman's blogspot regarding "Recent Trends in the Textual Criticism of the New Testament" by James Elliott (free PDF download; see http://bibleandtech.blogspot.com/). The latter is interesting with his discussion of the SBL/Holmes NT greek edition that was free in Logos (and recently updated).
But at least Elliott WAS complementary concerning Tim Finney's work and if you 'enjoy' statistical analysis of the NT textual variations, Tim's site is a 'gold mine'. Recommended.
