I'm curious about just who is this "we" that in "recent times" have discovered the misnaming of scripture authors. Who is currently doing research? What is being researched now that was not available when the books first came out? Is there a link?
Start here, and then just follow the links, publications, and names: http://en.wikipedia.org/wiki/Jesus_Seminar
My friend Kosta is more learned in this area than I am. We have the internal claims - Moses claimed to have transcribed the Torah directly for God, and Jews consider it divinely written; the rest of the OT is human commentary according to devout Jews. The NT is rather more interesting.
Luke, Acts, Hebrews, Matthew, Mark, James, and Jude actually have no internal claims as to authorship. Most scholars believe that Luke the Evangelist was actually the author of both Luke and Acts. Romans, 1 & 2 Corinthians, Galatians, Philippians, 1 Thessalonians, and Philemon are believed to definitely be written by Paul. Ephesians, Colossians, 2 Thessalonians, 1 & 2 Timothy, and Titus are questionable. James was almost certainly written after James the Just was martyred by as much as 50 years. Revelation was written by John of Patmos. Was this the same John that wrote the Gospel of John and 1,2, and 3 John? Probably not.
You may wish to investigate yourself; I do not have a good and up to date rigourous site that I can quote. But NT authorship is tricky, as there is no conspicuous signature or identification as there has been developed over the last millennium or so. Google can be your friend on this quest, if you are interested.
Sure, just Google "Gospels anonymous:" and see what you get. Or "authorship of Gospels." Or related words. Be creative. If you really want to study biblical scholarship in greater detail I recommend Prof. Robert Grant, a biblical scholar at the U. of Chicago for the past 44 years.
