tight : Used to mean that the binding of a book has not been overly loosened by frequent use.

remainder mark : Usually an ink marking of some sort which indicates that the book was designated a remainder. In most cases, it can be found on the edges of the text block in the form of a marker stripe or a stamp of some sort.

Remainder marks considerably lower the overall collectibility of a title, although, in some cases, they are acceptable to a collector.

shelf wear : Minor wear resulting from a book being place on, and taken from a bookshelf, especially along the bottom edge.
