Resumo:

In order to specify the place of a catchword within a text and, more specifically, in the book, it is necessary to know the main characteristics of the manuscript and the printed book, and it is done by using concepts from codicology and the bibliography material. Codicology deals with elements of the codex, or ancient manuscript, in order to perform, from observation, a description and interpretation of questions around the writing supports, ink, handwriting, how the books are organized, pagination, and sewing and binding among others. The goal is to reconstruct the phases of the codex procedure and the history of its use (Xavier; Mateus, 1990, p. 307, s.v. Codicologia).
