Gopher is another way to organize and access Internet information. It is a network of servers spread out all over the world, storing different types of information: texts, graphics, etc.
If this sounds familiar - you're absolutely right!
Gopher is the WWW's "older brother". It was developed a few years before the WWW and has been used mainly by academic and governmental institutions ever since.
Most Gopher information can't be found on the Web, and vice versa. That's why it's so important to know how to search for information on both Gopher and the WWW.
