The following sections of this appendix contain individual Data Sheets for each of the slide rules in the collection. Each slide rule has been given a unique identification number that is found in the section name for its Data Sheet. For convenience of the user, the sections of this chapter are ordered according to slide rule Maker, then by Model, and then by Year, although named by identification number. The browser search function can also be used to look for a particular slide rule in this scrollable list.

Attempts have been made to make a reference to each rule, such as a web page link or a reference to an article in the Journal of the Oughtred Society, etc. Many references that were entered a few years ago should be updated and I hope to get to those soon; but perhaps the ones here can give a starting point for each rule in the collection. Many of the more important reference articles can be found in References. To look up articles from the Journal of the Oughtred Society (JOS), visit the search page on their web site.
Regular documentation of acquisition dates began after August 1, 2020. Some items before that date have known acquisition dates, and a list of items in the collection was created in 2012 when there were 33 items. An acquisition date shown as precisely 09/02/2012 was acquired sometime before that date, and a slide rule with a date of 08/01/2020 was acquired between 09/02/2012 and 8/1/2020.
