I asked this question several months ago:
Title: What is a reasonable way to find canonical books?
I see dozens of questions of the form 'Is there a canonical book on {topic here}?'. My question is different. What are some reasonable ways to go about answering this kind of question for myself?
Currently I look at the most popular books in a category on amazon, but I find this unsatisfying, as the top spots tend to be filled with very introductory or very buzz-wordy books.
There were several thoughtful and thorough answers. Note that the answers were not reading lists but methods and resources for doing research. I'd like to know how I can modify this question such that it wouldn't be frozen and deleted.
This is a similar (but different) question, which seems to have been well received: How Do I Determine the Value of a Technical book? I don't believe its title reflect its final question: "Can you provide advice on finding more books along that vein (the Pragmatic Programmer)?"
:P
