Template:TitleFields:SeriesNum

• Series Number - If you know the order in which the books in the series are supposed to be read, you can number them starting with 1. You can use decimal numbers like 4.5 to place a title between the titles numbered 4 and 5. No Roman numerals (like I or IV) or letters (like "1a" or "A") are allowed. Please note that some series are very linear (e.g. Harry Potter) and it's easy to tell how to assign series number to individual entries. Other series can have different numbering scheme, e.g. it can reflect the series' publication order, internal chronological order, intended publication order, "author recommended" order, etc. Please don't change pre-existing numbering schemes unless you are sure that they are in error. Any series with this sort of ambiguity in internal ordering should have the sequence worked out on the Series project page. This includes prequels, which can be listed first in the series, before the main entries; or listed after the main entries; or even split into a separate series which then becomes a subseries in a superseries comprising both the original series and the prequels. If you are entering data for an omnibus which contains multiple works in a series, see the note on the length field which allows information about an omnibus's series contents to be recorded.
