This book doesn't appear to be used heavily. The cover, which is ivory card stock has yellowed a bit due to age. The spine is not cracked; there are no markings whatsoever in the book. The back cover has a crease in the top left corner, but all in all, in great shape. This is a seminal work by Hawisher and Selfe. From my personal library.
