Impact Factor
The Impact Factor can be considered to represent how many times an average article was cited in the previous 2 years How was the 2010 Impact Factor of “Journal-X” calculated? A = Total number of times all journals published in 2010 cited articles published in Journal-X in 2008 -2009 B = Number of articles published by Journal-X in 2008 -2009 Impact Factor = A/B

PUBMED Pub. Med is a Web-based retrieval system developed by the National Center for Biotechnology Information (NCBI) at the National Library of Medicine. It is part of NCBI's vast retrieval system, known as Entrez. Pub. Med is a database of bibliographic information drawn primarily from the life sciences literature. Pub. Med contains links to full-text articles at participating publishers' Web sites as well as links to other third party sites such as libraries and sequencing centers. Pub. Med provides access and links to the integrated molecular biology databases maintained by NCBI.
The diagram illustrates the relationships between the primary information resources in Entrez.
• MEDLINE is NLM's premier bibliographic database covering the fields of medicine, nursing, dentistry, veterinary medicine, the health care system, the preclinical sciences, and some other areas of the life sciences. • MEDLINE contains bibliographic citations and author abstracts from over 5600 journals published in the United States and in 70 foreign countries. It has over 19 million records dating from the 1946. • Coverage is worldwide but most records are from English language sources or have English language abstracts. • MEDLINE contains citations, not full-text articles (Pub. Med provides links to some full-text). • Each MEDLINE record is identified with a PMID and the tag [Pub. Med - indexed for MEDLINE]. • MEDLINE records are generally added Tuesday through Saturday.

4 PARTS OF ESI 1. Citation rankings § 2. Institution, Scientist, Country, Journal Most cited papers: long-term vs. “hot” § Highly Cited Papers (top 1% per research field) § Hot Papers (top cited in 2 month period) 3. Citation Analysis § Baselines against which to measure your performance § “Research Fronts” to track new trends 4. Editorial commentary § Science Watch
WHAT KINDS OF QUESTIONS CAN ESI HELP ME ANSWER? Which institutions produce the most highly-cited chemistry research? – Is my organization one of them? – If so, what is our ranking?
QUESTIONS FROM RESEARCHERS – Which researchers have published the most influential work in immunology over the past 10 years? – One of my researchers published a paper in 1999 in the field of microbiology. It has been cited 45 times to date; how does this compare to other papers published in this discipline? – I have just received a grant request and need to evaluate the applicant: Is this researcher highly-cited? Does he/she currently have any “hot” papers?
