PubMed Discovery Tools (Results by Year, PMC Images Search) Added!
PubMed “Results by year” and PubMed Central “PMC images search” tools now display in the discovery column for all PubMed users.
The “Results by year” timeline tool displays with search results of 10,000 or more citations. Mousing over the bars in the timeline will show the number of citations for each year. Click the right and left arrows to display older or newer years, and click the individual bars in the timeline to display the results for a single year.
The “PMC images search” tool displays for PubMed search results that meet a number of criteria, e.g., results with a minimum of 250 citations, filters are not active, the search does not include Boolean operators, the search retrieves a minimum of 4 relevant images calculated using a term weighted algorithm.
