resource-recommendation questions are on-topic but they need to follow the guidelines in our resource recommendation policy. Before asking a resource recommendation question, do your utmost to check whether there is a request about the same topic and whether the resources there are sufficient. It might be helpful to read the overarching books question Resource recommendations when doing this. Answers to resource recommendation questions must not be link-only or they will be deleted; we expect answers to describe the resources they recommend above and beyond what one might learn, for example, by trawling through Amazon.
Contrast this with the specific-reference tag, which is for questions that ask for a specific resource, instead of any resource explaining a particular topic. The tags resource-recommendations and specific-reference are mutually exclusive; they should never both be applied to the same question.
The resource-recommendations tag also covers journals and non-paper electronic materials, such as, e.g., video lectures, on-line resources, software, experimental data files, etc.
