The three papers in this collection were presented at the opening of the conference and the plenary session. The first is the "Presidential Address: Brighton, 1987 = Eroffnungsansprache zur IFLA Generalkonferenz Brighton 1987" (Hans-Peter Geh). These remarks by the President of the International Federation of Library Associations (IFLA) address the theme of the conference--"Library and Information Services in a Changing World"--with: (1) special attention to a view of IFLA since its founding in 1927; (2) recognition of the 110th anniversary of the British Library Association and the appropriateness of holding the conference on British soil; (3) the wide-ranging activities in library work in the Third World by IFLA; (4) education of the present-day librarians who must adapt to a rapidly changing social and technological environment; (5) new professional fields presenting new job possibilities; and (6) a summary of discussions concerning closer coordination between the professional work done in the Sections and Core Programs. Also included in this collection are: "Preservation Is Justified by Access" (Alexander Wilson, formerly of the British Library, United Kingdom), and "Is the Library a Source of Information in the Developing Countries? = Bibliotheque, Source d'information dans les pays en developpement?" (K. M. Aithnard, Director General, New African Editions, Togo). Two of the papers are given in both the original language and English. (CGD)
