Latest Impact Factor figures from Elsevier's Organic and Medicinal Chemistry Journals

We are pleased to bring you the latest Impact Factor figures from Elsevier's Organic and Medicinal Chemistry journals. 

Again Bioorganic & Medicinal Chemistry Letters (31,475 citations) and Bioorganic & Medicinal Chemistry (22,584 citations) are the 2nd and 3rd most cited journals in Medicinal Chemistry and Tetrahedron Letters (76,620 citations) the most cited letters journal in Chemistry.

We would also like to highlight an increase in the Impact Factor for Carbohydrate Research of almost 23%. 

We thank all the authors, reviewers and editors, for making these journals such a success.

Calculating Impact Factors

WHAT IS AN IMPACT FACTOR?
The journal impact factor is a measure of the frequency with which the average article in a journal has been cited in a particular year. The impact factor helps you evaluate a journal's relative importance, especially when you compare it to others in the same field. The impact factor is calculated by dividing the number of citations in the current year to items published in the two previous years by the total number of items published in the two previous years.

Using Journal X as an example:
Cites in 2011 to items published in: 2010
2009
Sum
= 258
= 199
= 457
Number of items published in: 2010
2009
Sum
= 116
= 71
= 187
Calculation: Cites to recent items 457 = 2.444
Number of recent items 187

The 2011 Impact Factor for Journal X is 2.444

Journal Performance Measurements
