For a complete guide to HTML, you can look at
``A Beginner's Guide to HTML" at
http://www.ncsa.uiuc.edu/General/Internet/WWW/HTMLPrimer.html.
If you're interested in looking at various WWW sites, Netscape offers What's Cool? and What's New? links under the Directory menu. Other browsers have similar links.
There are also many books published about HTML and the World Wide Web which you can find at local bookstores.
At the bottom of the Rensselaer homepage, you will find links to ``RPInfo Frequently Asked Questions" as well as ``How to get your information into RPInfo'', and ``Resources for RPInfo Information Providers'' which can be useful if you are interested in becoming an information provider. These links are located, respectively, at:
http://www.rpi.edu/About/faq.html
http://www.rpi.edu/About/infoprov.html
http://www.rpi.edu/About/resources.html
You might also want to join the Usenet newsgroup rpi.talk.rpinfo-providers, which is a forum for discussing using, creating, and maintaining web sites at Rensselaer.
