ADD NEW VOLUME (NOT ISSUE)

Sorry but i can't find a way to add new volume for a serie. I think you call it TP or hardcover or whatever... 
I got some actually and i can't find them in the base. 
I try to add one like we add new issues but i've been told it was the wrong way to do it. 
 
If anybody knows, please tell me, i can't wait to see some volumes that i have in here! :) 
 
Thank you very much. 
Sorry if this topic was already discussed, i try my best to understand english as well as i should.

Go to the browse button, highlight it, then go down to "volume." After the page loads, the yellow button in the upper right says "add new volume." From there, you know what to do!

A new trade paper back is still added as a new volume. The title of the volume should be what is stated in the indicia (the fine print usually found inside the cover). Then just label it issue #1 if it is the only one or the first volume.
