It is probably a good idea to test your HTML documents on a variety of different Web browsers, on a variety of different machines, and from a remote site.
<A HREF="document.html"> ... </A>
The ellipsis is filled in by the text that will appear as a label for the link in the document (the label is the highlighted text that will appear in a Web browser and which can be `selected' should one want to follow that link). The name `document.html' can be prefaced by a URL, so that a link to a document on another machine somewhere on the Internet would look something like this:
<A HREF= "http://machine.university.edu/Directory/document.html"> ... </A>
Some Web browsers even support dynamic uncompressing of compressed files. Material that is stored in compressed form on other machines will be retrieved, automatically uncompressed, and then displayed.
<A HREF= "ftp://machine.university.edu/Directory/document.txt"> ... </A>
<A HREF= "http://www.bris.ac.uk/Depts/Philosophy/Cyber/philcyb.html">Philosophy in CyberSpace</A>
<A HREF=""> </A>
and leave the cursor under the second quotation mark, ready for you to insert the name of the file to which you are creating a link.
