Web Resources
There is a rapid turnover of UFO material on the Internet. Many links to material on UFO websites quickly become out of date. Therefore, instead of giving many links to specific webpages I have instead focused on providing tables of references to discussion of UFO incidents, personalities and other matters in various books. Those tables of references to discussion in books can be sorted by author, length and date. I hope these tools are useful.
