In this section of the catalogue, lecture titles and dates are recorded as they are given by NK on the covers of files. However, it should be noted that these dates do not always reflect the period during which the contents were current. Many lectures appear to have been repeated over several years, with certain passages rewritten or page orders revised as required.
The lectures with references 2/1 - 2/30 were given at the London School of Economics and/or Cambridge University; 2/31 - 2/172 were given at various locations in the UK and abroad.
