From the Introduction:
The guide provides a survey of the sources (documents, manuscripts, maps and topographical reproductions) in the Netherlands for the history of Latin America. The area dealt with covers all of Central and South America together with the islands belonging to the relative countries, the southern states of the United States up to the time they joined the Union, and the Philippines. The period dealt with is from the discovery of America up to 1914, or, as regards the Philippines and Puerto Rico, to 1898. In certain cases the terminus ante quem has been shifted nearer the present day, for example if an archive or collection contains important documents from both before and after 1914 or a consecutive series of correspondence, etc, continues beyond 1914 and 1898 respectively.
