13.9 Provide information about document collections

You can navigate through document collections more efficiently and effectively if you understand how they are organised. If the page is part of a collection, provide information that identifies a document’s location within the collection. You can:

Include a table of contents, site index, or site map
Use page counters (e.g., page x of y) to indicate the position in relation to the whole set
Using <link> with rel or rev to indicate the URL of the next and previous pages for extra navigation information

Some browsers may synthesize navigation tools or allow ordered printing of a set of documents based on such markup.

For example, you might include the following <link> tags in the <head> tag of chapter 2 of a book:

The text-based browser Lynx will build a small menu of links at the top of the page that reads like this:

# Contents Chapter 1 Chapter 2 Chapter 3 Glossary

You can also bundle documents to make it easy to read them off-line. Use archiving tools such as zip, tar and gzip, and StuffIt to create the bundle.
