This use of replaceable punched cards to control a sequence of operations is considered an important step in the history of computer programming. "This large work is a description of how to set up a Jacquard loom. It begins with a description of the weaving process and the notation system used to describe a pattern. This is followed by an in-depth description of the Jacquard loom with very detailed full-page diagrams of the mechanisms. The final, and largest, part of the work is a sampler of different weavings, including their initial design documents and patterns together with swatches from the actual cloth." - Tomash & Williams.
