ToolBook

ToolBook is a SCORM and AICC compliant Microsoft Windows based e-learning content authoring application initially released in 1990 by Asymetrix Corporation, which later became click2learn and then SumTotal Systems. Asymetrix was founded by Paul Allen, one of the original partners in Microsoft.

For the first several releases ToolBook was seen as a competitor to Visual Basic as a Windows programming environment, to be used to create Windows applications. ToolBook 3 introduced the added ability to create training lessons, offering a variety of question types and scoring behaviors. With the release of version 5, ToolBook introduced the ability to publish a lesson into HTML format. Since that time ToolBook has been continually enhanced to allow for the HTML to be viewed on a wide variety of web browsers and mobile devices.
