Numbering Series - Multiple Books in One
I've searched the forum and haven't found anyone else asking this question, but feel free to point me there if it has been asked/answered before.
I have a few ebooks that consist of multiple books in one (i.e. Ultimate Hitchhiker's Guide). Is there a way to list the book in the Series field as containing books 1-5? Currently I'm using a period (1.5), but I was wondering if anyone has found another (better) solution.
