How does one cite a book series/sequence? I have a need to cite a certain scifi book series (i.e. a collection of books functioning as elements in a single larger story, not a series like the Springer Graduate Texts in Math) as inspiring a thought experiment in a philosophy paper, but I’m having trouble finding advice on how to cite a book series rather than a particular book in the series.

At least in this case it doesn’t seem appropriate to pick any particular book in the series (the relevant conceit is present across the whole series, but it’s quite possible some books in the series don’t mention it at all and I don’t even know which of the books I read).

Also, any suggestions for representing a series in BibTeX?
The Purdue MLA site provides a recommendation for how to cite an entire television series, which is essentially identical to citing a unified work: instead of naming an episode, one names the series as a whole, and the date shifts from a single point to a range.

By analogy, then, to cite a book series, one should simply use the series name as the book title, and list the range of publication dates, e.g., 

@book{LOTR,
 author = {J.R.R. Tolkien},
 title = {The Lord of the Rings},
 year {1954--1956},
 ...
