Really, you're not going to do much better in finding a stand-alone treatment of indiviudal writings than:

Other than that, I just have in my personal library the Jerusalem Bible, Charlesworth's OT Pseudepigrapha, Layton's Gnostic Scriptures (all published by Doubleday so they sit together well on the bookshelf), along with Martinez' and Wise/Abegg/Cook's DSS volumes, Wyatt's Ugaritic religious texts, Funk's Complete Gospels and New Gospel Parallels (2 vol.), Holmes' Apostolic Fathers, the three-volume Context of Scripture, the BHS, and various other criticial editions and commentaries; that satisfies most of my documentarian needs, other than what I have in my electronic library on my hard drive. I personally would prefer to see volumes of Levantine/Jewish literature organized without regard to canonicity but by historical era. So one volume may be pre-exilic writings where things like the Yahwist pentateuchal narrative, Psalm 29, Hosea, etc. would sit alongside parabiblical texts like the Book of Balaam son of Beor (8th century BC) and Aqihar (7th-6th century BC), and another volume would consist of exilic literature (such as Ezekiel, P, Deutero-Isaiah, etc.), another of Persian-era post-exilic literature, another of early Hellenistic era literature, another of Hasmonean-era literature, another of Second Temple Roman-era literature, etc. That would make it much easier for the casual reader to see the development of ideas and themes. The present artificial division between the OT and NT and the exclusion of Hellenistic literature on a bias of canonicity produces a gulf between the OT and NT that doesn't really exist.
