In 1999 a new edition of the ‘Guide to the International Archives and Collections at the IISH, Amsterdam’ (henceforth cited as GIA) was published. This new edition differs from the 1989 edition by Atie van der Horst and Elly Koen in the following respects: summaries of documentation collections are inserted with the summaries of the other archives and papers (to be distinguished from these by a clause like ‘collection of documents’, or ‘documents collected by’); collections on subjects have a chapter of their own now, next to the chapters ‘Persons’ and ‘Organizations’ and in a separate chapter there are summaries of papers, archives or collections which are preserved in other institutions, but of which the IISH holds reproductions, mostly in the form of microfilms or microfiches.
