Glossary

The words on a manga shelf are doing more work than they look. These are the meanings Hondana uses, so a volume number always belongs to an edition.

Edition
An edition is one publisher's line of a series: the same pages, the same format, and the same numbering. VIZ's Vagabond singles and VIZ's VIZBIG omnibuses are two editions of one series.
Printing
A printing is one manufacturing run of a volume that already has an edition. The second printing of Death Note volume 1 is the same edition as the first, and it is still a different copy.
Omnibus
An omnibus binds two or more volumes of a series into one physical book. A 3-in-1 is an omnibus. It counts as one book on the shelf and as a range of volumes in the story.
VIZBIG
VIZBIG is VIZ Media's oversized omnibus line. For Vagabond it is 12 books covering the 37 singles, three story volumes to a book.
Obi
An obi is the paper band around a Japanese book. In Hondana the same word is the short label for a collected format, such as 3-in-1 or 2-in-1, shown on a shelf entry.
Tsundoku
Tsundoku is the pile of books you own and have not read. Hondana keeps that pile one tap away by storing possession and reading as two fields.
ISBN
An ISBN is the 13-digit identity of a specific book, printed as a barcode. Hondana uses it to find an edition and a volume without asking a model to guess.
Possession and reading
Possession says whether the book is on your shelf. Reading says whether you have read it. They are independent, so an owned book can be unread and a wanted book can already be finished.
