indicate binding (hardback, trade, mass market, pamphlet) in import field

I'd like to move my database from an Excel sheet to TinyCat. I don't see a column for the binding. It's important. What would that column be called?

thank you

If you are doing an import, you have to use the columns set in the sample document. This is a normal import into LibraryThing. In LibraryThing you can add the media information.
