In 2009 the IFLA Cataloguing Section published Statement of International Cataloguing Principles (ICP) as an update of the Paris Principles adopted in 1961. The ICP aim to be applicable to online library catalogues and beyond. The statement aims to be the basis for an international cataloguing code and provides “only” general principles. It does not contain any practical cataloguing rules, but provides general principles for cataloguing. 

The statement is built on the conceptual model of Functional Requirements for Bibliographic Records (FRBR) and covers all types of resources and all types of access points including:

  • Subject headings
  • Classification numbers
  • Standard identifiers

According to the statement:

  • Authority records should be constructed to control the authorised forms and variant forms of names. 
  • Cataloguing rules should concern authority records as well as bibliographic records.
