The following menu selections from Herman van Herwijnen's SR Catalog(See Note at bottom of page), contains some 2,400 images which include 1700 slide rules, and 700 slide charts and associated pictures, many of which are not shown in the current ISRM galleries. This is a subset of the text file: Slide Rule Catalogue © Herman van Herwijnen, which was edited by Otto van Peolje in 2005, and contains 4,224 specimens. Slide Charts are rarely included in the ISRM Slide Rule Galleries, but are shown in their own Technical Slide Chart and Disk Gallery. Every item in the Slide Rule Catalogue starts with its brand name, if available. Manufacturer's names or brands are listed alphabetically with a MATCH (catalog ID number) along with a description of the scales. Clicking the MATCH number pops up the picture of that slide rule.

Note: From the early 1990's Herman van Herwijnen, member of the Dutch Circle, has worked on his "Slide Rule Catalogue" project, with the aim to produce a book with descriptions of all slide rules known within the Dutch Circle. As the project progressed, the goal expanded into a computer based database with pictures in color of each slide rule. In 2003 the Catalog database contained more than 5000 slide rules and slide charts with over 3000 pictures. Since Herman van Herwijnen died in August 2004, the Catalog has been frozen in its last version 5.3 of September 2003. During 2005-2006, this consolidated version, with Diny van Herwijnen's approval, was split into a "TEXT Version" and a "LITE Version" with pictures now available on ISRM as part of the public domain.
