Tailored keywords and meta-information allow narrowing down the set of studies to be considered. In this way, repositories provide relevant information for academics, policymakers, the public, journalists, and industry. This facilitates more efficient evaluation work in the official sector (including international organizations), for academic researchers, and the industry.
Repositories are well-established in some fields such as medicine, where the Cochrane Library or the McMaster Health Forum20 provide structured evidence on medical research, also by compiling meta-studies. Similarly, in the field of development economics, the International Initiative for Impact Evaluation (3ie) collects information on the effects of policies and programs in development economics.
