Some Web information is presented as hypertext. With it you may not only read a screen from beginning to end, but also jump to related information from highlighted text like this if you select it with your mouse (if you're using a GUI interface) or enter the attached number ( if you're using a line-mode interface). When you come to the end of a WWW page, move the scroll bar down (GUI) or press the "enter", or sometimes the "return", key (line-mode) to get to the next page.
WWW provides access to many information sources other than hypertext screens. You may directly query data bases like SPIRES and Oracle, view USENET news items and plain text files, explore FTP, Gopher, and other network information systems, look at images and movies, listen to speeches, and invoke commands--as these sources have been made accessible to WWW. Material from remote locations is retrieved over the Internet and may actually reside almost anywhere in the world. The point of origin is often not directly communicated to you.
WWW is a highly distributed, client-server application. You use a client called a "browser" (like Mosaic) to see WWW information. Several browsers are available at SLAC, which support GUI or line-mode style for various platforms including Macintosh, PC, UNIX, and VMS.
N.B.: World Wide Web information is particularly dynamic. Over time links may move around on a page, migrate to others, or be removed entirely as more appropriate locations are found, links become obsolete, or they are superceded by improved ones.
For a detailed summary of the World Wide Web from SLAC, peruse the SLAC Home Page. It is designed to provide diverse information for the various needs of active members of the SLAC community, wherever they are in the world.
There are actually two forms of the SLAC Home Page, a Highlighted one and a Detailed one, because people have different styles of work. All the information on the "SLAC Home Page: Detailed" appears on the "SLAC Home Page:Highlighted" or on one of its major Secondary Pages like "SLAC Research." To investigate the central SLAC Web and the pages linked to it, start out at either of the following Home Pages:
These three pages, the Welcome and the two Home Pages, comprise the SLAC Core Pages.
For background on the reasoning that led to this structure, see "A Model for the SLAC Laboratory Core Pages" in the WWW Style Committee's Report. (Note that the Welcome, Highlighted, and Detailed pages were called the Institutional, Sparse, and Dense pages there.)
In addition, there may be a Test version of the Detailed SLAC Home Page.
You may change your default page from the Welcome Page to either of the Home Pages or another of your choice. Some general instructions are given in " Changing Your Browser's Home Page Default."
See also the WWW Style Committee's Report, which treated these and other recommended page elements.
