This research identifies the similarities and differences between the MathSciNet search features and functions of the American Mathematical Society (AMS) and EBSCOhost platforms. A series of iterative MathSciNet queries were performed on both platforms. For each query, the total number of results and search behavior were documented and analyzed. Observations and comparisons are quantitative. The findings surface the need to deeply understand the AMS and EBSCOhost platform features, functions, record metadata, and indexing for MathSciNet. Furthermore, this research can serve as a foundation for additional quantitative and new qualitative comparisons between these two platforms and also for other platforms.
