Visualizing Pub MedPubMed is an invaluable resource, enabling searching of a large portion of the biomedical literature and serving as perhaps the most popular entry point to MEDLINE. As an interface however, it is primarily geared towards presenting results in the form of a long, paginated list. This works well for examining individual citations, but is a poor fit for getting a larger sense of how one search compares to another (or how the results of a particular search compare to the database as a whole). For this purpose, it would be better to see searches in aggregate. Even better would be to display and compare searches using a variety of criteria.
