I added a custom column called #omni which has come to be really Omnibus OR Anthology. It even displays now as O-A. It's a checkbox field. Obviously, just anthologies that are NOT collections (Best of the year, etc) have no series info, although a story contained there in CAN be a series short story that you want to denote.

Soooo, a second custom column called #endvol lets me have my cake and eat it too. I fill in the starting number in the series index and then the end of the compilation in End Volume. Then I check O-A. (You might think that's overkill). I then sort my selected books by #endvol and then by series index and send the list to my device in the order I want them to show up (reverse order in the case of Kindle Paperwhite). The template has been changed to detect an entry in the #endvol and, if so, attach a dash and then that number to the series index part of the title I've created. Bob's your uncle.

Easy to manage. The template took a few seconds worth of remembering CHaley's instructions and that was it. I use to use the decimals to work out compilations, 1.23; 4.56 etc. But somehow, some of my favourite authors have managed to get past the ten volumes in a series (hey, shout out to readers of Perry Rhodan). Plus, I've started storing comic collections in Calibre as HC (#hardcover) or PB (#paperback) and the system I'm using does well with issue numbers.

Just a suggestion. GM
