M.R. James' Old Testament Legends: Being Stories Out of Some of the Less-Known Apocryphal Books of the Old Testament has been keyed and is now available via Project Gutenberg.

Here's the TOC:

ADAM
THE DEATH OF ADAM AND EVE
ABRAHAM
THE STORY OF ASENETH, JOSEPH'S WIFE
JOB
SOLOMON AND THE DEMONS
THE STORY OF EBEDMELECH THE ETHIOPIAN, AND OF THE  DEATH OF JEREMIAH
AHIKAR

What I'm not aware of is whether or not these are translations or retellings. They are not versified; so I'm inclined to think they may be retellings instead of formal translations. The preface does list the source(s) used for each document.

There's also a zip file with some of the page images (illustrations).

Update (2005-12-13): Jim Davila (Paleojudaica.com) links and adds comments and more links about M.R. James, his writings, his contributions and further discussion. All worth the read. Go check it out.
