Our analysis of the FNB demonstrates the research potential of openly available data resources. In particular, we have enriched and augmented the raw MARC entries that have been openly released by the National Library of Finland, and are hereby openly releasing the harmonized data set so that it can be further verified, investigated, and enriched by other investigators. The open availability has  allowed us to implement reproducible data analysis workflows, which provide a transparent account of every step in data analysis from raw data to the final summaries.
