Second edition of the Pocket Book of the Gauge Marks by P. Venetsianos.
From 2006 through 2010, new members of the Oughtred Society were pleasantly surprised to receive
with their very first Journal a complimentary copy of the Pocket Book of the Gauge Marks by
Panagiotis (Pano) Venetsianos. The booklet contained some sixty pages of gauge marks, the special
marks along slide rule scales for often-used constant values.
The Oughtred Society is out of stock of these original booklets; however, Pano has now published
under the aegis of the Oughtred Society a second edition of the booklet, greatly extended to more
than 140 pages. This new version is available for sale to ALL slide rule collectors at the no-profit
cost price. The Internet on-demand publishing service Lulu has been chosen to produce and ship the
second edition booklets. The initial price is $8.94 excluding shipping (typically $3.99 USPS).
