Excerpt from New System of Classification and Numbering: In Use in the Mechanics' Institute Free Library
His System is as nearly mnemonic as possible, intending to aid both the public and Library employes.
The classification of knowledge is arranged to fall in succession, each sub-class a relative part of the main class It is divided into three parts - Class (a), sub-class (b), and a division Any person with an ordinary education and a small knowledge of books and their authors can find books, should the readers fail to supply either class letters or number, or both. Example: If a book on music is wanted, the messenger will know that music is a fine art. Class F, and sub-class 77: (music), where a guide card shows the numbered division wanted. This system is more expansive than here represented, as not all the letters of the alphabet are used, leaving room for more classes, also very few sub-classes or divisions are used up.

The author, a world-renowned expert in the field, explores the development of the system from its origins in ancient mathematical practices to its revolutionary uses in Islamic astronomy, engineering, and architecture. Using it, Muslim scholars produced major advancements in trigonometry, algebra, and calculus centuries before European scholars.
