In 2011, KTH Royal Institute of Technology adopted a policy on scientific publishing geared towards creating full accessibility of research output. The main objective of this report is to assess the long-term effects of this policy. To that end, we collected and analysed publishing data at KTH, along with related expenditures. More specifically, we track changes in counts and shares in open access publishing over the past decade, as well as describe trends at multiple levels of analysis, ranging from conference proceedings to journal article publishing at KTH and its affiliated schools. Additionally, we provide insight into both the past and present state of open access publishing, and briefly discuss the future of open access publishing at KTH. This report is aimed towards all interested in publishing practices at KTH. Throughout this report, we use concepts and definitions derived from prior year documentation and analysis of open access publishing at KTH.
