It's very common for users to want to find references about a specific topic in machine learning, statistics, or probability. Often, these questions start from a place where the user doesn't know what they want to know, so it is challenging to give a good answer. A vague question - a question with little context or explanation of what kind of information is sought - is very likely to be closed as "Needs details or clarity."
So how should a user who does not know what they want to know ask for references (books, articles, tutorials, websites) about an area with which they are unfamiliar?
