About Journal Citation Reports
The Journal Citation Reports (JCR) was first produced in 1975 by the Institute of Scientific Information (ISI), now Thomson Reuters. It was first produced using data from the Science Citation Index. Today JCR is available in two parts: one for the Sciences based on data from the Science Citation Index and the second, based on data from the Social Science Citation Index.
Today JCR is widely used to identify the top journals in a field. These are rated based on citation behaviour. The journals are ranked in JCR using the well known and accepted journal measure – the Journal Impact Factor (JIF). JIF is often used by individual researchers to identify the best titles in which to publish and gain recognition and potential impact. It is important to note that the JIF of journals in different disciplines will vary considerably. This is because citation practices can vary significantly from one field to another. The JIF cannot therefore be used to compare journals across different subject areas.
