There are two main types of cataloguing:
* Bibliographic cataloguing creates a record of the physical item itself.
* Authority cataloguing creates a record of the person, organization, or concept that is the subject of the item.
Bibliographic cataloguing typically includes the following information:
* Author: The person or organization responsible for creating the intellectual content of the item.
* Title: The name of the item.
* Publisher: The organization responsible for making the item available to the public.
* Date of publication: The date on which the item was published.
* Physical description: A description of the item's physical characteristics, such as its size, binding, and pagination.
Authority cataloguing typically includes the following information:
* Name: The name of the person, organization, or concept that is the subject of the item.
* Dates of birth and death: The dates of birth and death of a person, or the dates of establishment and dissolution of an organization.
* Occupation: The occupation or role of a person.
* Pseudonyms: Any pseudonyms or alternative names used by a person.
* Subject headings: Terms that describe the subject matter of the item.
Cataloguing is a highly specialized field, and cataloguers must have a deep understanding of the principles and practices of cataloguing. Cataloguing is also an important part of librarianship, and librarians play a vital role in ensuring that library and archival collections are organized and accessible to users.
