This set aims to provide comprehensive mechanical engineering reference material in a user-friendly format. It addresses the need for readily accessible and detailed technical information for engineers, machinists, and students.

The inclusion of both a print and CD-ROM version suggests an effort to cater to different user preferences for accessing technical data. The 'Larger Print' edition indicates a consideration for readability, potentially targeting older professionals or those who prefer larger text. The set is likely regarded as a valuable, albeit potentially dense, resource for professionals in mechanical engineering and related trades.
