Element: Page Count

Book 2.1

Number of pages in a printed book or book component; by convention, each page or partial page is counted as one. Electronic documents do not traditionally have page counts.

This element may also be used in a <citation> to indicate the total number of pages of a referenced item, typically a book component such as a chapter.

Many elements in this DTD Suite were created explicitly for import conversion, that is, so that the intellectual work of tagging done by publishers would not be discarded when they converted material from another DTD to the NCBI Book DTD or NCBI Collection DTD. The count elements are a perfect example of this rationale; they are conversion elements and should only be tagged if present in the original source.

The count elements are modeled as EMPTY elements (that is, elements that have no content and store their real values in one or more attributes) because the majority of DTDs that were examined in the course of preparing this DTD Suite used this mechanism, an inheritance of the older MAJOUR-header DTD.

Inside the <counts> wrapper element are the counts of various components of the book: the <fig-count> is the number of figures, the <table-count> is the number of tables, the <equation-count> is the number of display equations, the <ref-count> is either the number of references or (more properly) the number of citations in the bibliographic reference list, the <page-count> is the total page count, and the <word-count> is the number of words in the book.

A number of elements in the Suite relate to page numbers:

<fpage> names the page number on which a book component (such as a chapter) or a cited article begins;
<lpage> names the page number on which a book component or a cited article ends (which should be the same page number or a number larger than the starting page number);
<elocation-id> replaces the start and end page elements just described for electronic-only documents;
<page-range> records discontinuous page ranges for a cited article (See note below.); and
<page-count> holds the total page count, if the publisher has provided one. Typically this element records what the publisher said and makes no validity claim.

Note: The <page-range> is intended to record supplementary information and should not be used in the place of the <fpage> and <lpage> elements, which are typically needed for citation matching. The <page-range> element is merely a text string, containing such material as “8-11, 14-19, 40”, which would mean that the article began on page 8, ran through 11, skipped to page 14, ran through 19, and concluded on page 40.
