Today Pieter Belmans added an online bibliography to the Stacks project; see his blog post here. If you are used to reading the Stacks project online, then you’ll now find direct links to the bibliography entries on the tag lookup pages. A good example is the introduction to the chapter on Popescu’s theorem.
Of course the bibliography isn’t perfect and we’ll work on that. Moreover, I think we could sprinkle more references throughout the text. Please don’t hesitate to send in motivated suggestions for citations (even to your own papers) to firstname.lastname@example.org.
