Subject:  NWWA Master Catalog Library

District and project offices of the Water Resources Division that
do a great deal of test drilling and well testing may be
interested in the Master Catalog Library recently published by the
National Water Well Association.  The library, contained in a
single encyclopedia-sized desk-top volume, includes microprinted
reproductions (9 per page, generally at about a 1:3 reduction) of
10,000 catalog pages issued by 350 suppliers to the ground-water
industry, an index and directory of suppliers, a product index,
and a source-of-supply directory.  A handheld illuminated reviewer
is furnished with the volume, though much of the material can be
read with the naked eye.

Attached is a reproduction of the Catalog Index, to show the
nature of the material included.

Offices desiring to place orders for the library should submit
their orders directly to the address given below.  Information
that the order is from an office of the Water Resources Division
will enable obtaining a special price of $95 for the library, in
place of the regular price of $125.

Offices desiring to be placed on a mailing list to receive
information on this and similar material, whether or not they
order a copy of the library, should send their requests to the
same address.
