Reb highlighted several great links for studies in the Old Testament including this Online Book page hosted by the Society for Biblical Literature (SBL). Kar Yong posted it here and I cannot believe I missed it! I am not blind, but definitely very blur.
The site "provide free online PDF files for a variety of SBL publications to scholars and students who would not otherwise have access to this scholarship. Persons who are identified through our technology as being from a country with a GDP per capita substantially lower than the average GDP per capita of the USA and the European Union will be able to see links below to PDF files."
Check out Reb's post here for more OT links.
