Category scope: This category and its subcategories are only for articles describing a series of books as a whole, not for articles on individual books contained within a series. This particular category is only for series that cannot reasonably be classified in one or more of its subcategories. Note on the terms "series" and "sequence." This distinction, for example in Category:Novel series and Category:Novel sequences, is meant as follows:

• A series is intended to be read sequentially. This term is also apropos for series where some reading order is preferable, but which may not consist solely of novels, such as the 1632 series, wherein about half is short fiction, half novels, and sometimes the years in the book have nothing to do with published order in our time line.
• A sequence is a series of books that are otherwise related—which are a set or series of novels which have their own title and free-standing storyline, and can thus be read independently or out of sequence or in sequence regardless of sharing a particular milieu or timeline. See novel sequence.
