There was a question some days ago asking for 3rd party resources or references, tagged with reference. After the question got closed, the OP asked me about the purpose of the tag, which caused me to have a closer look.
The current description for reference reads
A short, to-the-point, document summarizing a topic ...
but by scanning through the list of 50 questions tagged with it, I could detect only one or two using the tag in this sense. The other questions seem to use it in the sense of the Wikipedia definition:
A reference is a value that enables a program to indirectly access a particular datum, such as a variable's value or a record, in the computer's memory or in some other storage device.
So should the tag description be changed, or should it be extend it to mention both possible meanings?
