The web provides a very unique opportunity for the interconnecting of researchers and their work into an evolving online community of scholarship. However, that scholarship will not thrive if people are not given credit for their work and ideas. Researchers will just stop publishing their work online and will revert to the traditional publishing methods. Encourage the development of this new and exciting realm of scholarship!
If you use someone's ideas or work, cite them. They will appreciate it. And if you are using their work on your own web page, email them and let them know that you would like to add a link to their page. It not only contributes to the evolving network of knowledge, it also is common courtesy.
There is no one correct way to cite online publications. Each discipline has its own standards. Here is how you might apply to my work one commonly used format:
Suler, J. Title of article. In Title of the Book, address for the article (the month and year you accessed the article)
so that would look like...
Suler, J. The basic psychological features of cyberspace. In The Psychology of Cyberspace, truecenterpublishing.com/psycyber/basicfeat.html (accessed October 2013)
At the top of each article in my online book The Psychology of Cyberspace, you'll see dates indicating when the article was first published online, and when the last revision occurred. So you have the choice of using the citation format listed above, or the following possibility, which I might recommend in many cases:
Suler, J. (year article was most recently revised). Title of article. In Title of the Book, address for the article (year article was originally published)
so, for example...
Suler, J. (2002). The basic psychological features of cyberspace. In The Psychology of Cyberspace, www.rider.edu/suler/psycyber/basicfeat.html (article orig. pub. 1996)
