Would this allow for proper sorting within series? Let me mention another type of series I track. Harlequin/Silhouette publishes numerous category romances every month, almost all of which are numbered books. Many of these, however, are part of ongoing author or multi-author series. The data field you have in calibre is meant to track the author/multi-author series. But say I wanted to track the category romances, so I could see how many of those I have and see them in their proper numerical order? Would adding it in comments or tagging it allow for that, or do I need to add the book # in the line with the book's title?
My thanks to all those who have taken the time to read and reply.
