Erica Wheeler papers This series comprises mostly raw data and compiled results taken from a number of research projects in which Erica Wheeler was involved. There are notebooks and food diaries, sample analysis, questionnaires and research data. All the material apart from the Esso survey was taken from a much larger set of papers and data. Only a few examples remain from a number of different surveys - this is why the data seems incomplete. Also, reports and publications can be found in 13/17-19. 1967-1989
