Reference structures are the systems by which a document exposes its various modes of organization so that they can be pointed to and referred to, by other texts and also within the document itself. They also include systems through which the document itself points to other documents or to places within itself. Examples of reference structures include pagination, signatures, chapter and section numbering, systems of bibliographic citation, tables of contents and indexes, and (in an encoded document) systems of unique identifiers that enable specific elements to be pointed to. The entries listed below give more detail on specific topics.
