Hello and welcome to my blog site about slide rules. This represents the newest incarnation of my slide rule sites, the earliest of which was online in 1998! Since then, and through several different service providers, I have had original slide rule related research, collecting information, and usage tips provided free for your enjoyment.

Be sure to browse through the pages linked through tabs at the top of this page, and also to be sure to check out the list of links to the right. There you can find many interesting sites, including a link to my last site on Geocities as saved on WebArchive. This is a HUGE repository of information on the slide rules manufactured by the companies Relay, Ricoh, Nikkei, and Dietzgen, and all of the variousl sub-brandings related to those companies.
