These Guidelines constitute the third edition of the International Federation of Library Associations (IFLA) "Multicultural Communities: "Guidelines for Library Services." This revision follows the IFLA Section of Library Services to Multicultural Populations' "2006-2010 Strategic Plans": to review and revise the Guidelines, taking into account new technologies, and professional and societal developments which have impacted upon service provision and directions. These guidelines have been compiled and published in order to promote fairness and equity of access in library services to multicultural communities. The guidelines, provide a basis for the planning of library services to all groups in the community; provide criteria against which the adequacy of existing multicultural services may be assessed; provide an equitable basis for the acquisition of materials and the provision of services; and encourage understanding and engagement among the multicultural groups represented in all societies. It is intended that they be used in conjunction with standards and guidelines for particular types of libraries in each country and with international standards, rather than taken in isolation. The central principle of these guidelines, that of equity, should be used in applying existing standards and guidelines for public, school, academic and other libraries. It is also important that library services to multicultural communities should be seen as an integral part of any library's full range of library and information services, rather than in isolation or as an addition to traditional library services. The structure of these guidelines corresponds to that of "The Public Library Service: IFLA/UNESCO Guidelines for Development, 2001," so that librarians may more easily use them in conjunction with each other. Two appendices are included: (1) The IFLA Multicultural Library Manifesto; and (2) "Raison d'etre" for Multicultural Library Services.
