The LILACS Methodology establishes the creation of bibliographic records at two levels of processing:
Source record – data of the book as a whole or of the journal issue;
Analytic record – data of the book chapter or the journal article.
For the creation of the record of the work as a whole: the book, the journal issue, the non-conventional document, or the thesis/dissertation.
Example of a source record of a monographic series:

Example of a source record of a journal issue:

Analytic Record:
Refers to the description of book chapters or documents, or journal articles.
This type of record has its own title, authorship, and bibliographic references. The complete content of the analytic record makes it unnecessary to read previous or subsequent chapters or articles.
An analytic record is always linked to a source record and cannot exist without this link. When this does not occur, the record cannot be retrieved.
Example of a list of analytics of a monographic document:
