I noticed today that we now have a reference-request tag. Anyone who has been on the site for a while will know that literature recommendations and "list" questions are offtopic.
A lot of the questions are not asking the sorts of things we wanted to avoid when we discussed literature recommendations. Many of them I think added reference-request to signify that they wanted answers that were backed up by published material. For example How does identification currently work with the German identity card?. If the question specifically asked "In what book/paper can I find out how the German identity card works?" obviously that would have been offtopic.
At the same time, newer visitors who don't know that literature recommendations are offtopic might see reference-request and be led to believe they can ask a question such as "Can anyone suggest a reference for how AES works?"
What should we do with the tag and/or questions?
