Faculty of 1000 Medicine (F1000M) saves you time and effort by identifying and rating the most current high-impact articles and providing expert opinions that explain the key findings and critical impact.
The evaluation and commentary in F1000M is provided by a “faculty” of more than 2,400 top global clinicians and researchers, including seven at UT Southwestern. Faculty members select, rate, and comment on two to four of the most interesting papers they read each month. Rating levels include “Exceptional,” “Must Read,” and “Recommended.” By rating articles based on their individual merits rather than the journal in which they appear, this system provides a useful alternative to impact factors and citation scores.
Features include:

• “Hidden Jewels”: Identifies high-impact articles published in less widely distributed journals.
• Top 10s: Lists best, classic and most-viewed papers across the whole of medicine or by specialty.
• My F1000M: Displays most recently selected papers in your field of interest.
• Email Alerts: Sends you notices tailored to your area of interest.
• Advanced Search: Runs and stores simple or sophisticated searches.

F1000M has recently added F1000M Reports, a journal that publishes short commentaries by expert clinicians that focus on the most important studies that are likely to change clinical practice. The commentaries summarize the implications of new research findings for clinicians.
Faculty of 1000 Medicine is a sister product to Faculty of 1000 Biology. To find F1000M on the Library Web site, use the “Quick Links” box.

JCR (Journal Citation Reports) presents quantitative data that aims to give an objective view of the world’s leading scientifc journals and their impact on the global research community. The JCR Impact Factor is the average number of times an article from a journal published in the last two years has been cited in the JCR year.
How might you use the Impact Factor number? If you are considering submitting an article for publication to two journals (e.g., one with an Impact Factor of 1.2220 and the other with an Impact Factor of 3.503), you would probably submit the article first to the journal with the higher Impact Factor because articles in that journal are – on average – cited more frequently and theoretically are read more than articles in the other journal.
JCR has recently added enhancements:

• Five-year Impact Factor: Offers a longer-term view than the standard two-year Impact Factor.
• Eigenfactor Metrics: Uses citing journal data from the entire JCR files to reflect influence and prestige by considering scholarly literature as a network of journal-to-journal relationships. For more information, go to Eigenfactor.org.

JCR offers additional information about each journal:

• Immediacy Index
• Article Influence Score
• Cited Half-life

To help you understand and interpret the data presented in JCR, the publisher has provided:

• Information for New JCR Users
• A JCR tutorial
• Using Journal Citation Reports Wisely
• JCR Quick Reference Card

A caveat: Impact Factors attempt to measure the overall impact of a particular journal. They do not quantify the impact of a particular article. You can find further discussion of this and other aspects of Impact Factors in the Impact Factor article in Wikipedia.org.
