These are 500+ reference materials in the the ISRM Library collection, which involve books, manuals, instruction sheets and sales brochures. Electronic files may be scans (200 dpi) of these materials or may link to or reference scans from other sources for your convenience. Credits are given to all contributors of scanned materials.

    Please Consider a Monetary Donation

    All the images of slide rules in the galleries and the PDF files of scanned books, manuals and instructions have been free to download since 2003. The policy of ISRM is to continue this practice, without restrictions in order to provide research and educational information to the world at large. However, running a web site of this size with a large amount of data does take a lot of personal time and effort and does incurr costs in hosting in order to provide the bandwidth. It takes many hours to scan slide rules and manuals. ISRM gets many hits per day from appreciative visitors, collectors and researchers. If you have enjoyed the many offerings of ISRM, and would like to partner toward its expansion, you can send donations using the Secure Paypal button on the right. Contributions will be used to pay for the web site service, putting on public exhibits and expenses for the Slide Rule Loaner Program for schools. Thank you for your support and consideration!

    New - Hardcopy Slide Rule Instruction Reprints from the ISRM Library Available on Amazon

    This is a giant preservation project and is ongoing! If you have downloaded any of the manuals in the ISRM Library, you were probably dissapointed in the quality of the digital scans. Many years have gone by since then, and much of the paper ephemera has deteriorated. With an enourmous amount of work, all the manuals have been rescanned, aligned and processed to the point that they resemble the original documents printed by the manufacturer. These scans are now in the reprints available through Amazon. Every one of the 540-550 page Volumes contain most of the popular models from each of the brands, or by country or language are available in paperback ($19.95) or hardcover ($27.95) on Amazon, which will print to order in 7 countries. Click on the covers to go to the relevant page on Amazon to review and purchase the Volumes. The small royalty goes to support ISRM Its equivalent to buying manuals for $1-$2 each!. Download the Table of Contents of all Volumes. Note: Honestly, a direct donation helps the operation of ISRM more than the royalty received on these books, but you will love having them in your personal or instututional library.
