We currently have the tag the-dark-tower, which has been tagged for a question about C. S. Lewis' novel The Dark Tower. However, there are several other literary works with the same title:
Should we replace the current tag with the-dark-tower-lewis and later create similar tags when questions about the other works are submitted?
Per my answer here and the following discussion in comments, we should disambiguate the tag by adding the author's name to the tag name.
I think that a single book tag should refer only to a single book. It will be confusing to use the same tag for questions about different unrelated works which happen to share a title.
If tags should be a way of marking out a specific area of expertise, well, nobody's going to be an expert on "all books entitled The Art of War", but someone could well be an expert on Sun Tzu's The Art of War or on Niccolo Macchiavelli's The Art of War.
How do we handle tagging when multiple unrelated books have the same title?
A simple solution would be to add the author name into the tag name. Then we could have questions tagged with the-art-of-war-sun-tzu and the-art-of-war-macchiavelli and so on.
This was implemented in that case by renaming the existing the-art-of-war tag to the-art-of-war-sun-tzu.
The only question here, then, is whether we should use the-dark-tower-lewis or the-dark-tower-c-s-lewis. Any thoughts on this?
the-dark-tower-lewis show up in a search for "Lewis"? That wouldn't work with the publication date as part of the tag.
