roup list of co-operating firms would be of interest.

The following list is not complete, as it includes only those who have
co-operated in the production of a portion of the volumes, constituting
the first printing. As soon as the entire list of books comprising the
Typographic Technical Series has been completed (which the Committee
hopes will be at an early date), the full list will be printed in each
volume.

The Committee also desires to acknowledge its indebtedness to the many
subscribers to this Series who have patiently awaited its publication.
