During the last 50 years, universities have undergone a dramatic change which may be described as the transformation from elite to mass higher education. Usually these developments are quantified by referring to student numbers, and Volume 8 of the Data Handbook on German Educational History (Gottingen: V&R, 1908) follows this approach. Volume 10 may be considered a supplement to Volume 8, as it turns around the perspective and studies the personnel employed at the universities. Again, the data demonstrates growth and structural change, which are obvious characteristics as soon as the personnel of the emerging mass university becomes the subject of a statistical description. Volume 10 of the data handbook handles the data by dealing separately with the following variables: personnel grouped by status and functions (senior and junior faculty, assistants etc.) subjects of teaching and research gender age annual habilitations (second theses) employment (full or part time) sources of income (budget, contract money) Empirically, the data come from the annual publications of the Statistische Bundesamt. The data have been reorganized into time series which subsequently are presented by some 300 tables (on CD) as well as by some 150 figures (included into the text). German text.
