The document discusses the journal impact factor as a measure of academic publication influence, calculated based on citations and citable items from previous years. It also explores alternative metrics, known as altmetrics, for assessing individual article impact, highlighting additional resources for researchers. A bibliography of key studies and resources related to impact factors and altmetrics is provided.

3. Journal Impact Factor
– This is a number determined by Thompson
Reuters
– 2008 impact factor = A/B
• A = the number of times that all items published in that journal in 2006 and 2007
were cited by indexed publications during 2008.
• B = the total number of "citable items" published by that journal in 2006 and 2007.
("Citable items" for this calculation are usually articles, reviews, proceedings, or
notes; not editorials or letters to the editor).
