The WWP textbase contains two different kinds of advertisements: conventional advertisements for other books (usually appearing in the back of the book, but sometimes in other places such as on the title page or within the text), and prefatory prose describing the current book, often titled something like “Advertisement to the Reader” and written by the author or the publisher.
1. The prefatory prose should be encoded with <div type="prefatory">. For more detail, see entries on front matter and prefatory material.
2. Conventional advertisements for other books take several forms. In some cases, they appear as brief notes in places where <div> is not allowed, such as on the title page. In other cases, they may appear as lists in a section of their own, in places where <div> is allowed. To accommodate both kinds, the WWP uses two separate elements to encode these advertisements: <advertisement> and <div type="advert">.
The <div type="advert"> element should be used to encode groups of advertisements which appear where <div> is legal. Individual advertisements within this division should be encoded with the <advertisement> element. We do not use the <list> element to group them; if they are numbered, the number should be encoded using <label> within the <advertisement> element. Note that an individual advertisement may refer to more than one book: the choice of where one advertisement ends and another begins should be based on the natural groupings evident in the text (for instance, the placement of headings or price information) rather than on references to individual books.
In addition to the use within <div> described above, the <advertisement> element should be used independently to encode individual advertisements when they occur where <div> is not legal (for instance, on title pages).
Within the <advertisement> element, there may appear a number of elements which resemble a bibliographic citation or title page, such as publication information, author and title, and the price. These should all be encoded as a bibliographic reference, using <author>, <title>, and <imprint>, nested within a <bibl> element. The price should be encoded with <measure>. (See entry on <measure> for more information.) We do not use <biblScope> (e.g. for volume numbers or for the book format); we simply transcribe these without markup.
