For many years, the accessible source for ancient texts related to the Bible was Ancient Near Eastern Texts (ANET), edited by J. B. Pritchard.  A few years ago Context of Scripture (COS), edited by Halloanet and Younger, was completed, giving a more extensive and up-to-date source for these texts.  ANET still has its place though because

1) all sources more than a decade old provide references only to ANET and

2) ANET has some materials not included in COS

COS has been available in Logos format for a few years ($300 here), and now ANET has been announced as a pre-publication special, which means 1) it will only be produced if enough orders are placed and 2) you can get it for less money if you order now ($60 instead of $80).
