Bachelor and Master theses of Leiden Universtity
As a rule, printed BA and MA theses were not included in the library collection. Starting 2010, BA and MA theses of the Faculties of Archaeology, Humanities, and Social and Behavioural Sciences are included in the Student Repository of Scholarly Publications. These theses are not included in the catalogue, but the titles can be found in Google Scholar.
If you are looking for an unpublished thesis it is advised to contact the secretariat of the department where the author of the thesis concerned has graduated.
At the Wijnhaven library you can find theses of Public Administration that were handed in between 2010 and 2011. The theses are available for loan.
