Embase content & coverage
Embase 1947 - 2012
Multiple perspectives highlight different aspects of Embase
Scope now extends over many niches in biomedicine
• Scope and coverage• Embase focus areas• Journal content 2012• Journals by country & language• Journal selection policy
Agenda
Excerpta Medica Abstract Journals (1947/8)- 15 abstract journal titles, growing to more than
40- abstract journals (not citation indexes)- controlled indexing (later branded as “Emtree”)
Evolution of Embase (1947-2012)
EMBASE database online (1974)- first commercial offering via Lockheed Dialog- now available on multiple online platforms
EMBASE becomes Embase (2009)- additional MEDLINE content licensed from NLM- online availability extended back to 1947- original abstracts (1947-1974) become available
as Embase Classic
Embase scope and coverage (2012)
Other topics 28%
Including public health, basic biomedical science and topics included from MEDLINE
Embase vs MEDLINE scope
Similar overall pattern of coverage... but with two major differences
1. Pharmacology & toxicologyEmbase: 11.2% (889 titles)MEDLINE: 8.3% (465 titles)
2. General clinical medicineEmbase: 10.5% (835 titles)MEDLINE: 8.9% (495 titles)

Embase vs MEDLINESearching the difference
Peer-reviewed literature in biomedical science
Embase focus areas
- Drug therapy and research, including pharmacology, toxicology, pharmaceutics and pharmacoeconomics
- Public health, including occupational and environmental health
- Basic and applied biological science relevant to human medicine, e.g. physiology, biotechnology and forensic science
- Health policy and management
- Biomedical engineering + medical devices
- Clinical and experimental (human) medicine,including psychiatry and mental health
Embase traditionally includes much literature in health-related topics such as:- Complementary and alternative medicine 89 journal titles in
Embasee.g. Osteopathische Medizin (Urban und Fischer)
- Substance dependence and abuse traditional topics initiated
- Pollution control relevant to human medicine as EM abstract journals
Embase content - additional topics
In addition, with the expansion to include all of MEDLINE, Embase now has extensive coverage of:- Nursing 270 titles- Dentistry 183 titles- Veterinary science 123 titles
Embase (active) journals in 2012
