errata ( erratum )
Errors or omissions in writing or printing,
generally restricted to typographical errors, but
sometimes including imperfections in either
presswork or binding. They are usually printed on
a separate slip or leaf and placed among the
preliminaries, or added to an existing page of
type at the beginning or end of the book. Errata
sheets must frequently be tipped in by the library
or the binder. (69 )
