XML Topic Maps book I edited and co-authored (2002) (at Amazon.com) Still in print (it says here).
The Wind Power Book I wrote (1982) (at Amazon.com) Out of print.
Prototype TopicSpaces Knowledge Garden (topic map) platform: http://www.topicspaces.org:8080/wiki/ which runs on a very slow DSL line (be kind to it and don't let it get to Google), which includes Tagomizer (social bookmarking), Open Questions (issue mapping), and several other experimental applications, some of which are not fully wired--think: work very much in progress. The wiki platform is really the map itself; applications provide views into the map specific to domain needs.
Transcluding tags from TopicSpaces for the tag GENIS:Source, which relates to energy sources. Note that links above each bookmark point directly to the Web resource; other links point into TopicSpaces itself. This mashup is implemented as an HTML iframe, so, clicking on a link will open within the iframe itself (and look rather ugly).
