Endocrinology, the Societys" oldest journal, has defined the science of endocrinology for most of the twentieth century. One of the most authoritative biomedical research journals in the world, it publishes 6,000 pages annually of the highest quality original work ranging from subcellular mechanisms to whole animal physiology. Topics include bone and mineral; growth factors; reproductive/steroids; neuroendocrinology/signal transduction; thyroid; and physiology. The low manuscript acceptance rate of 30% reflects the degree to which it is committed to the highest scientific standard. In the 2008 Thomson Reuters Journal Citation Report, Endocrinology received a 5-Year Impact Factor of 5.255. Published monthly.

Impact Factor

Impact factor (IF) is a scientometric factor based on the yearly average number of citations on articles published by a particular journal in the last two years. A journal impact factor is frequently used as a proxy for the relative importance of a journal within its field. Find out more: What is a good impact factor?

III. Other Science Influence Indicators

Any impact factor or scientometric indicator alone will not give you the full picture of a science journal. There are also other factors such as H-Index, Self-Citation Ratio, SJR, SNIP, etc. Researchers may also consider the practical aspect of a journal such as publication fees, acceptance rate, review speed.

The h-index is an author-level metric that attempts to measure both the productivity and citation impact of the publications of a scientist or scholar. The index is based on the set of the scientist's most cited papers and the number of citations that they have received in other publications
