Something that I've been thinking about for a while...

Let's say, if I had plans for self-publishing a comic series with further plans to collect the issues in bigger trade paperbacks down the line... This is the way I'm considering doing it.

Issue (Alternating between longer five-part arcs and shorter two-to-three-part arcs...)
Book (issue #1-5, #6-10, #11-15 etc...)
Volume (Issue #1-25, 26-50 etc...)

I'm thinking that "Book" comes before "Volume", as each issue could be considered a "chapter"...

Or would you suggest another naming scheme? I know that "omnibus" and "compendium" pops up frequently as well, but I'm just not sold on those words. What sounds best?

"Virtus: Volume I" sounds good for a big 628-pager...

Help me make up my mind!
