This is for info on what books or literature are good, and where to find them. Personally, links to expensive papers where the abstract promises the world, but the paper doesn't deliver (the norm) are deprecated...We want to know about the good stuff here, rather than pay taxes once for the research, then enrich a greedy publisher once again who didn't really contribute value and has already made money on the journal the article appeared in. There are exceptions, but they are few indeed.
