Based on the Newnes Pocket Book, this Windows-based software presents a reference for electronics engineers. Each topic, such as a transistor's characteristics or an integrated circuit's pinout details, is presented as point-and-click pop-ups. The Factfinder can by searched by keyword, chapter heading, or by pages sequentially, or even compiled into user-defined folders. Each of the Newnes Factfinders builds up into a coherent data library, and the user has the option of searching for a topic or item of data across all the Factfinders they have purchased.
