Archives of the Peruvian Corporation, 1849-1967, comprising the surviving records accumulated at the London Office of the Peruvian Corporation. The bulk of the collection is an accumulation of files, most of which are dated after 1930, with a large proportion dating from the last ten years of the Corporation's history. Of more special note is the unusual series of photograph albums, with photographs of railways, scenery, locomotives and rolling stock dating from the early years of the 20th century. It is clear that the Corporation regularly destroyed groups of non-current records, and further papers were destroyed just before the collection reached the Library, so many expected series do not appear (for example, there are very few financial records). Apart from a full series of Annual Reports and some legal documents, there is very little material relating to the Peruvian Bondholders' Committee or to the early days of the Corporation.
