For some reason we have a books tag. I propose that we burninate it.
It tells you nothing about the content of the question.
You can't be an expert on "RPG books".
There are exactlytwo questions that have only the books tag, and both of those would be better served by having a tag that explicitly focuses on acquiring RPG rulebooks (physical or electronic).
Discussion of the tag has come up before, but it 1) was lumped in with online-resources, which is somewhat more defensible, 2) didn't receive a lot of attention from what I can see, and 3) happened before we decided to ban recommendation questions. For that reason I think it's worth rehashing the topic in a new question.
There are 73 questions currently tagged with it, and the majority seem to be correctly using the tag. It doesn't appear to be causing problems, which is one reason to burninate a tag.
Would the site benefit notably from the tag not existing? I don't see any particular benefit that would motivate a burnination, but I could be overlooking something.
I do see some losses though:
The tag's meaning is questions about books qua books. We have a substantial number of questions that are about books as objects in and of themselves, rather than their contents (where the tag shouldn't be used / should be removed). These would mostly end up with a single system tag if books were burninated, and become indistinguishable from uncategorisable questions about a game, and unsearchable. That curated data would be lost.
It's possible to be an expert in books in and of themselves. Librarians, collectors, and booksellers come to mind as common examples. Although it's a very small part of the site, our topic does include the book-collector aspect of the RPG hobby.
People interested only in book contents and RPG play can add books to their ignore list. I can't imagine this will ever be a popular use of the tag, but it's a legitimate use.
People who are experts at locating books, how to tell book editions apart, publishing histories, and book identification, and the other subjects about books qua books could favourite the tag. Again not a popular use of the tag (currently 0 people have favourited the tag), but a legitimate use.
