Specialist's display book

A display book was traditionally a written chronological record of all limit, stop, and short sale orders that had been placed with a specialist for an individual security on behalf of specific clients plus an inventory of the specialist's own holdings in the security.

The New York Stock Exchange (NYSE) Display Book® is an electronic extension of that recordkeeping. It's part of an integrated telecommunications system that not only displays orders but executes and reports transactions, handles trade comparison, and links to a number of other functions.
