PubMed Impact Factor Search is a Chrome add-on developed by tand826. It falls under the category of Browsers, specifically Add-ons & Tools. This free program aims to simplify the research process by utilizing impact factors.

With PubMed Impact Factor Search, users can add search words to the PubMed search box, which are the ISSNs (International Standard Serial Numbers) of specific journals. These ISSNs correspond to journals that have the desired impact factor, as specified by the user using a slider.

The latest version, 4.1, includes an added link to the InCites CSV export page. Users are required to add a CSV file, which can be exported from InCites Journal Citation Reports. The CSV file should have specific column names, including ISSN, Journal Name, and Impact Factor. PubMed Impact Factor Search can read the newer format of exported CSV files.

Installation of the add-on involves setting up the CSV file in the settings tab. It's worth noting that InCites exports only the top 600 results, so manual concatenation may be required for more results.

Overall, PubMed Impact Factor Search is a valuable tool for researchers looking to streamline their PubMed searches based on impact factor criteria.
