Chapter 6. Cross-Referencing

Our documents contain a lot of numbered things such as pages, sections, list items, figures, and tables. There's even more we have not covered yet. For instance, if you would like to write a mathematical text, you may number equations, theorems, definitions, and many more.

We number things not just to count them, but to refer to them in other places of our document. If you want to point the reader to the ninth figure in the third chapter, you might write "See figure 3.9". LaTeX automatically enumerates the figures for you. If you insert another figure, LaTeX will automatically adjust the numbering of all figures after it. But what's with the references?

LaTeX is able to take care of all of our cross-references. This is the subject of this chapter. We shall learn how to:

• Set labels that we shall use to refer to

• Refer to sections, footnotes, list items, tables, and more

• Refer to page numbers and ranges

• Make LaTeX refer verbosely to adjacent pages

• Automate naming of references...
