I often see postings like this:
Hi! I am a highschool student and want to know all about cold fusion.
Where do I start?

There is a large literature on this subject. Probably the best way is to start with the two books
These books take opposite points of view and describe the early history very well, as well as the technical aspects. They are a little dated by now, although much of the cold fusion story took place back then. For a more up-to-date view, go on to read
- again, taking opposite points of view (Beaudette and Storms positive, Park very negative). Details (publishers etc, and a short abstract) of all these can be found in the file Books. If you want still more, start browsing through these web pages. There are other books, for example, and around 1400+ scientific papers for the intrepid. There are archives at the LENR site (google it).
