In an attempt to document the inconsistency and complexity of bibliographic control of names of international conferences, this directory provides a list of variant names used by such organizations. Preceding the list is a presentation/discussion of the seven recommendations made by the IFLA Working Group on Corporate Headings in April 1977, to resolve this problem. The entries are arranged in Dewey Decimal order, and each name is tagged with a sequential number or date to indicate the changes it has undergone. The distribution of the types of namings analyzed in the collection (e.g., one name which never changes, two or more parallel names which alternate with acronyms) is displayed in a table, as are the frequencies of acronyms. All of the names recorded here were derived from publications used at the Royal Institute of Technology in Stockholm. (JD)
