I think the tag story-identification has been used too enthusiastically, since several questions are not about stories:
- Anthology of literary theory that illustrates each theory by applying it to the same works is definitely not about story identification; the central concern is literary theory.
- Looking for a book (possibly a pair of them) with whimsical illustrations of misheard phrases isn't about stories either; the interest is more "linguistic".
- Complete, single book of Peanuts comics?: Peanuts comics may be story, but a collection is not a story.
- Which Biography of Einstein: one may consider biographies as stories, but the question is "which biography?", i.e. which book. We already know what the story in question is, namely Einstein's biography.
So I would support a separate book-identification tag which would be applied to (at least) the above question. The tag wiki excerpts should make the difference between the tags more explicit.
Update: merging both tags into a new tag named identification would be a bad choice, since identification is a term with a different meaning: the "psychological relationship between the reader of a novel and a character in the book".
