IFLA. Bibliography Section– This IFLA section is primarily concerned with the content, arrangement, production, dissemination and preservation of bibliographic information, especially (but not exclusively) where these pertain to national bibliographic services. It is also concerned with the promotion of the importance of the discipline of bibliography to library professionals in all types of library (not just national libraries), to publishers, distributors and retailers and also to end-users. Whilst taking full account of technological possibilities, the Section is aware that such developments are not yet available in some areas of the world, and it will ensure that its solutions are not necessarily dependent on particular technologies. The Section is closely associated, where appropriate, not only with the other Sections within the Division of Library Services but also with the Section of National Libraries.

IFLA. Cataloguing Section – The Cataloguing Section analyses the functions of cataloguing activities for all types of material and media, including both bibliographic and authority information, for the benefit of all users. The Section proposes and develops cataloguing rules, guidelines and standards for bibliographic information taking into account the developing electronic and networked environment in order to promote universal access to and exchange of bibliographic and authority information.

IFLA. Classification and Indexing Section

IFLA-CDNL Alliance for Bibliographic Standards (ICABS) – The National Library of Australia, the Library of Congress, The British Library, the Koninklijke Bibliotheek, and the Deutsche Nationalbibliothek agreed to participate in a joint alliance together with the Biblioteca Nacional de Portugal, IFLA and CDNL to assure ongoing coordination, communication and support for key activities in the areas of bibliographic and resource control for all types of resources and related format and protocol standards. This alliance was known as "IFLA-CDNL Alliance for Bibliographic Standards (ICABS)." The focus of the alliance was strategic and offered a practical way to improve international coordination and to steer developments in these key areas. The alliance aimed to maintain, promote, and harmonize existing standards and concepts related to bibliographic and resource control, to develop strategies for bibliographic and resource control, and to advance understanding of issues related to long-term archiving of electronic resources, including the promotion of new and recommended conventions for such archiving. ICABS was superceded by ICADS.

IFLA-CDNL Alliance for Digital Strategies (ICADS) – ICADS was established in August 2008 as a successor to ICABS which was established as a national libraries initiative in 2003. The ICABS work plan supported a number of goals relating to the development and use of bibliographic standards, resource access and managing electronic resources. Since 2003 it has become increasingly clear that a major challenge for most national libraries is managing digital resources. In response to this development, IFLA and CDNL wanted to see a stronger focus by ICABS on digital library issues. Consequently, a new framework was developed by the ICABS Advisory Board to provide a more comprehensive view of the wide range of issues related to digital library management and within which to represent relevant innovative projects and initiatives. The new framework was renamed ICADS to reflect the increased concentration on digital library development and management. In December 2011 the ICADS Advisory Board decided to close ICADS and cease its activities. This decision followed consultation with ICADS member libraries and with IFLA representatives.

IME ICC – IFLA Meetings of Experts on an International Cataloguing Code

Integrated library system (ILS) – Software (though in early incarnations a software/hardware combination) that provides housekeeping activities and management information in relation to library services.  Modules available can include cataloguing, acquisitions, circulation, OPAC, inter-library loans, periodicals control and reading list organization. It is becoming increasingly important that elements from these systems interoperate with wider institutional systems such as Portals and VLEs. (Prytherch, 2005, p. 361)

International Congress on National Bibliographies (ICNBS) Recommendations – 1998, Copenhagen. Recommendations concerning to specific topics of national bibliographic services, e.g., legal deposit, coverage and presentation of national bibliographies and international standards used.

Interoperability – The ability of computers to communicate with each other using a common set of protocols. (Mortimer, 2001, p. 96)

ISBD – International Standard Bibliographic Description. The family of International Standard Bibliographic Descriptions specifies the requirements for description and identification of information resources, assigns an order to the elements of the description, and specifies a system of punctuation for the description. Responsibility for the development and maintenance of ISBD resides with the International Federation of Library Associations and Institutions – Section on Cataloguing.
