CODEX PSEUDEPIGRAPHICUS VETERIS TESTAMENTI, edited by Johann Albert Fabricius in the early 1700s, is now available online for downloading in various formats.
Alex Panayotov has placed it here, downloadable in two installments in PDF format.
You can also find it at www.archive.com in DjVu, HTML, and PDF formats. And maybe one or two others, although the Full Text version doesn't seem to have come out properly - and it hung up my Firefox browser.
This is the earliest scholarly collection of Old Testament pseudepigrapha. I have more on it and its editor here. Enjoy!
