A dream to do a “J. K. Rowling” and write a book for children has yet to happen but as the passion for my hobby took hold so did writing about slide rules and other calculating aids - at least my often light-hearted take on them.

Most are written in English but the odd one is in Dutch. I mainly publish my articles in one of the collector-orientated publications:

• US: Journal of the Oughtred Society (JOS)
• UK: Slide Rule Gazette and Skid Stick newsletter
• NL: Mededeling en Informatie voor verzamelaars van Historische Rekeninstrumenten (MIR) newsletter
• DE: Rechenschieber-Brief electronic newsletter (superseded by online website in 2004)
• xx: Proceedings of the annual International Meetings (IMs)

Use the BROWSE ALL ARTICLES option to list all my articles, the most recent first, with a short summary and associated keywords to help you choose. For any article in the list click on the highlighted download option to get a PDF version of the article. 

Use the SEARCH BY KEYWORD option to list just the articles covering a particular topic or special area of interest. For any listed articles meeting your criteria, click on the highlighted download option to get a PDF version of the article.

Please note many of the downloadable articles are updated/extended versions of the original.
