The Kinematic Models for Design Digital Library (KMODDL) is a collection of mechanical models and related resources for teaching the principles of kinematics - the geometry of pure motion. The project is supported by the National Science Foundation (NSF), produced by Cornell University Library, and will be included in the National Science Digital Library.

The KMODDL project has selected fifty books and other print documents for digitization and inclusion in the collection. These stem principally from the nineteenth and early twentieth centuries; some are older, and several are rare titles from Cornell Library's History of Science Collection.

These items constitute a freely accessible and searchable digital collection of the historical literature of kinematics and the theory of machines. The materials were scanned in a nondestructive process and stored as 600 dpi TIFF image files backed by searchable OCR'd text.

Images and PDFs of these pages are available in a reader similar to the pages in other Cornell retrodigitization projects, such as the Historical Mathematics Monographs.
