Partners' filing

In about 1900 the correspondence of the partners was reorganised. In- and out-letters were then arranged in date order and letters were filed according to subject and, in some instances, correspondent. All the papers on a file were indexed, always by in- and out-correspondent and very often by subject. The filing system was therefore very sophisticated; the technique used may well have been imported from the US and was doubtless implemented by specialists.

The files gradually replaced the House Correspondence contained in the annual deed boxes and therefore this series constitutes a highly important source. After 1900, and especially after 1910, the deed boxes were used mostly for storing telegram messages, copies of which were held on Partners' Files.

Files cover the wide range of subjects with which the partners dealt. They exist for every major transaction, including proposed ones which did not take place. Most of the transactions were bond issues; few papers relating to the work of the Credit Dept exist. In addition there are files of letters exchanged with specific firms, for example corresponding banks and agents, and other files contain miscellaneous papers relating to specific countries and are referred to as 'Affairs'. Some files relate to the administration of the firm, e.g. premises and staff matters.

A second 'supplementary' series of Partners' Files exists. They are thin files and, presumably for convenience, were stored in the annual deed boxes. However their content is of the same nature and importance as the 'main' series of Partners' Files.

Between 1900 and the 1950s approximately 1000 'main files' and about 300 'supplementary' files were created. The following selection of titles indicates some of the subjects covered.
