Contains research material that appears to have been collected and used in numerous publications, talks and lectures resulting in overlap between the items in this series. U DDB/3/1 consists of material that was collected for a book that does not appear to have been published. However some of the material was used to inform subsequent published articles so they have been included in this section. U DDB/3/7 comprises single articles and research material that does not appear to have a clear published outcome.

The material has been left in the folders it was deposited in and the titles used, although this may not be a true reflection of the file's content. Some duplicates have been removed. Material that explicitly refers to a publication has been grouped together, but other material has been listed separately, but may still be connected.
