I understand the problem (I've also experienced it, as a new user in public beta), but I don't think that a [novel] tag is the solution. It has the potential to get really messy, and is [not in keeping with the general purpose of tags](https://literature.meta.stackexchange.com/a/567/481). As long as this site is new enough to retain "beta" status, there is an intentionally [low(ered) reputation][1] required to create new tags. 150 points is really not a lot, especially for new users who already have an account (with 200+ points) elsewhere on the network. 

In the event that a new user does come here, asking a question about a work or author without a tag, a high-rep user will be along to fix it soon enough.
