Synopsis, one of:
\frontmatter \mainmatter \backmatter
book class document differently according to which part
of the document is being produced. All three commands are optional.
Traditionally, a book’s front matter contains such things as the title page, an abstract, a table of contents, a preface, a list of notations, a list of figures, and a list of tables. (Some of these front matter pages, such as the title page, are traditionally not numbered.) The back matter may contain such things as a glossary, notes, a bibliography, and an index.
\frontmatter declaration makes the pages numbered in
lowercase roman, and makes chapters not numbered, although each
chapter’s title appears in the table of contents; if you use other
sectioning commands here, use the
*-version (see Sectioning).
\mainmatter changes the behavior back to the expected
version, and resets the page number. The
\backmatter leaves the
page numbering alone but switches the chapters back to being not
numbered. See Larger book template for an example using the three.
