# Tag Info

LaTeX's standard commands for generating cross-references are \label and \ref.
There are many packages enhancing LaTeX's cross-referencing capabilities, for instance , prettyref, nameref, titleref, , xr and . The last two are outstanding: xr allows cross-referencing to other LaTeX documents and hyperref can produce hyperlinks in PDF documents. Since the latter is a very complex package for which we've got many question, please use the tag instead, if your question specifically concerns this package.
