To help scientists decide which one of the many systems to use, we have tested some of the most relevant applications (commercial and non-commercial) as to how well the respective software performs in five different categories. These reflect the most significant abilities and features of reference management software. In the table below, each application is rated in each category with a simple star rating system (1 = poor, 5 = perfect). Clicking on the star ratings opens a detailed comparison table with more information about the test results. The order of the applications in the table reflects the order in which they were added to the comparison.
