The essence of hypertext is that documents are linked to other documents. This means that you may find many useful resources by following links from related documents.
Look at Yale's Research Guide to Christianity: Internet sites page to get an idea of the extent and variety of resources available on the Internet. . Pick a topic of interest to you, then follow the links you find interesting at that site, and so on.
When you have found a useful resource after following a series of links, it's possible to go straight back there without following the same path. Make a note of the internet address (or Uniform Resource Locator - URL) which is shown after the word Location: at the top of the screen. The next page of this guide shows you how to use URLs to go directly to a Web site. If you are using your own computer to browse the Web, a simpler way to keep track of where you've been is to use bookmarks, which record the URL for you and allow you to quickly return to the site.
