The WWP encodes all front matter, and uses the TEI <front> element to group it together. This includes all material appearing before the main text of the document, including items such as preface, foreword, introduction, acknowlegement, dedication, abstract, table of contents, frontispiece, title pages, and other miscellaneous prefatory pieces.
The WWP uses <div type="prefatory"> to tag any substantial segment of introductory material in prose or poetry (with a few exceptions, see below), including prefaces, forewords, introductions, memoirs, “advertisements” and addresses to the reader. We use <div type="prefatory"> regardless of who wrote the segment in question.
For more specific sections of the front matter, we use the following encoding:
<div type="advert"> (for advertisements of other books only)
<div type="castlist"> (for cast lists printed in the text)
<div type="contents"> (for tables of contents)
<div type="corrigenda"> (for errata lists)
<div type="dedication"> (for dedications in prose or poetry)
<div type="frontispiece"> (for a frontispiece)
<div type="prefatory"> (any prefatory material not covered by the other front matter values listed here; replaces the old values ack, foreword, preface, and frontpart)
<div type="prologue"> (for the prologue of a play)
<div type="undetermined"> (for any section of front matter which cannot be described using existing type= values)
One of these values must always be specified; see the section on <div>.
Prologues to plays or novels, where such a prologue was written to be performed with the play, or to be read with the novel, rather than to introduce a particular edition, should be encoded using <div type="prologue"> as part of the <body> element, unless some other indisputably <front>-like element intervenes.
Note that sections of the frontmatter which are labelled “Advertisement” may not always be advertisements for other books. Many texts contain prefatory material (often written by the publisher) which is labelled “Advertisement” or “Advertisement to the Reader” and describes the contents of the book or apologizes for some imagined failing. These “Advertisements” should be encoded as <div type="prefatory">. Advertisements for other books, often in the form of a list and typically at the end of the volume, should be encoded as <advertisement> within <div type="advert">.
