The **Name and Title Authority File of Catalonia**  **(CANTIC)** is an authority union catalogue within the Union Catalogue of Universities of Catalonia (CCUC), that it is led by the library of Catalonia known locally as Biblioteca de Catalunya. The goals are to bring order to the bibliographic catalogues, to improve communication among catalogues and finally, to make getting information research brought to them faster. CANTIC treats those who control name and title authorities related with Catalan culture in a higher regards. These authorities receive a complete authority work and are provided, eventually, access to the Catalonia Encyclopedia or known locally as Enciclopèdia Catalana.

Definition and aims
-------------------

CANTIC has the aim to be the catalogue of authority records created cooperatively by Catalan libraries. These records have to be generated from the authority control of name, name-title and title access points of Catalan bibliographic records. This guarantees the standardization and uniqueness of access points of catalogues, which makes it easier the exchange and a more efficient communication of bibliographic records and, in the end, enables users to carry out assisted, precise and exhaustive searches. 
CANTIC is a national service that allows to standardize and give consistency to the catalogues of the Catalan library system; it is the tool that facilitates the creation of the future Unique Catalogue of Catalonia (CUC), devised in the frame of the Agreement of the Catalan Government of 20 July 2004, for the improvement and modernization of Catalan Library System.

History and evolution
---------------------

At a meeting held on 16 September 2002, the Advisory Commission of Cataloguing, the advisory body of the Biblioteca de Catalunya in terms of cataloguing, talked about the need of creating a list of authorities in Catalonia. It was decided to establish a subcommittee to study the technical feasibility of the project and to prepare the requirements and functionality of the list of name and title authorities, taking into account the real needs of the Catalan Library System. The Subcommittee met for the first time on 27 March 2003 and finished the job in October 2003. In the report prepared by them are presented:

1. The definition and aims of the list.
2. It provides an overview of the state of art in and out Catalonia, and ascertains that the current situation of the authority control of the Catalan Library System does not satisfy the existent needs neither avoids the duplication of tasks, efforts and costs. Following the model of other international experiences, it is stated that a unique authority list in Catalonia, prepared cooperatively, is a feasible project that favours the exchange of bibliographic records and the information research and retrieval.
3. They give the bases for the creation of the Catalan Name and Title Authority List, and comment in brief the cooperative model of a subject authority list, since its operation and organization differ substantially of the name and title list.
4. They specify the requirements and functionalities of the software of Catalan Name and Title Authority List.

The Name and Title Authority File of Catalonia was created following the Catalan Library System Act, Llei 4/1993 "La Biblioteca de Catalunya supervisa, valida i unifica en un sol llistat el catàleg d’autoritats"
