When project resources are limited, where should researchers' priorities lie? The Priority Setting Project Database catalogs research articles that explore that question, with the goal of serving as a "source of inspiration," and a "research tool for unanswered questions and under-researched topics." The database includes sectors from agriculture to communication to law, although the bulk of the projects are in the health field. Examples of recent additions to the database include an article on prioritizing future research in vitiligo treatment and another on setting a research agenda for Latino childhood obesity in the U.S. The database currently holds 775 projects from around the world, which are searchable by topic, year, country, stakeholder, and research method. Readers can use the drop-down menus on the left side to filter their search. A summary of each project can be accessed by clicking "Show More." The database was developed by the Ludwig Boltzmann Gesellschaft Open Innovation in Science Center, which is funded in part by the Austrian National Fund for Research, Technology and Development.
