I realize that this isn't a great help, but from the NETAworld.org website, you can download the exam_reference_list which specifies which standard/book/article is to be used for studying broken down to which test you are taking.
This is still very vague, but atleast you can actually see which standards and books they require you to obtain your information from. I personally have been working on slowly obtaining all the references and putting them into a study folder for my co-workers.
