Embase Classic covers almost two million biomedical and pharmacological citations drawn from 3,000+ international titles published between 1947 and 1973. Since older records contain considerable information that drives present-day research, an Embase Classic subscription is beneficial for current research. For further details please contact your regional office.
Embase has significant content that is not available from PubMed/MEDLINE. Also, the Embase indexing makes even information shared by the two databases uniquely retrievable from Embase.
- 2700+ journals not indexed on PubMed/MEDLINE, especially from countries outside North America
- 1.75 million+ conference abstracts from 5,500+ conferences (since 2009)
- In-depth drug and medical device indexing based on the Emtree Life Science thesaurus, which has over twice as many terms as the MeSH (the MEDLINE thesaurus)
Scopus includes most, but not all, Embase content, as well as the Embase index terms. Scopus searches focus on abstracts and citations, while a search in Embase provides additional insights as a resul the structured full-text indexing of content.
Since Scopus does not use Emtree to facilitate synonym mapping and hierarchical searches, it may retrieve significantly fewer results than Embase. For example, a Scopus search on "heart attack" misses records mentioning "myocardial infarction" or indexed using the Emtree term "heart infarction".
In addition, Embase subheadings are not available on Scopus, so searches cannot be focused in the same way. For example, it is not possible to limit drug searches to records focusing on adverse effects.
More than 5,500 new records are added to Embase every working day, corresponding to over 1.4 million records each year. Of these, about 83% are indexed by Embase and 17% are additional MEDLINE records licensed from the National Library of Medicine. Articles in Press and In Process records are added to Embase as soon as they are available. Over 400,000 of the records added to Embase each year are conference abstracts.
Fully indexed records in Embase (excluding MEDLINE records licensed from the National Library of Medicine) are manually indexed using the full text of each article. Index terms identified by trained indexers with a biomedical background are checked against Emtree before being added to the records. These indexed records are available online within two weeks, on average, from the receipt of the journal issue.
For licensed MEDLINE records, index terms assigned by the NLM from the MeSH thesaurus are mapped to Emtree.
Articles in Press, In-Process records and Conference abstracts are automatically indexed.
Please refer to the Embase Indexing Guide (PDF, 468kb) for more information.
Usage statistics are automatically emailed to Embase yearly subscribers on the first day of every month. The report includes year-to-date statistics for the number of sessions, number of searches and the types of searches (quick, advanced, EMTREE, author, journal) executed. Please contact your regional help desk to set up a usage report.

Embase customers discuss the role of biomedical literature research in their daily work.
Embase is an essential resource for post-market monitoring of medical devices — I can't imagine doing that kind of safety monitoring without it. Dr. Su Golder, a research fellow at University of York (PDF, 764kb), focuses on adverse events and assessing methods for finding adverse events across a broad range of literature sources. In this interview, she talks about the current state of adverse event monitoring and systematic review planning.
Embase serves as an exhaustive knowledge resource that I and other researchers in multiple locations around the world can share. It lets us locate and annotate scientific data that is crucial for our research project communications and new scientific proposals. Avinash Permraj, a research scientist at Management of Scientific Centers (PDF, 628kb), uses Embase to deal with the ever-increasing amount of information on biological processes, novel techniques and new concepts in animal biotechnology and veterinary research data. He explains how he and his colleagues use Embase to support their work.
As an environmental scientist, I don't need to go deeply into biomedical research but I still require full and up-to-date information in this field for geographic and ecological impact studies. Everything I need from biomedical journals I get from Embase. Dr. Elena Koroleva, a senior lecturer at Moscow State Lomonosov University (PDF, 653kb), wants to ensure that she, her research group and her students have all of the biomedical information they need to understand the environmental and human impact of medical developments. She discusses how Embase supports her in this task.
The main challenge we have is finding the right information for our research and not wasting our time on irrelevant results. We always have a lot of work because the research staff needs us to support them comprehensively. Edith Clausen, a research librarian at Aarhus University Hospital (PDF, 601kb), works with the staff to find research literature that supports their clinical, research and educational duties. In this interview, she talks about how Embase helps her quickly and confidently find the information her colleagues need.
Emtree really helps me because if I find an interesting paper, I can review similar papers through the terms of the entry. Compared to the way of searching in other tools, it's much easier. Dr. Federico Aletti, a research fellow at the Politecnico Di Milano (PDF, 593kb), conducts research in the cardiovascular field. He explains how Embase lets him find papers faster than other research solutions.
I have an alert compiled to send me the newest product-related articles at the beginning of each month. This email helps me to be aware of potential hot topic requests. Dawn McMillen, a library resources supervisor at Stryker Orthopedics (PDF, 676kb), must ensure that her colleagues have all the information they need for their work. In this interview, she describes how Embase helps her stay up to date, and her colleagues informed.
I use Embase when I want to be sure that I've checked all the scientific literature I can for information on a given drug. I mainly use it for drug-related searches because that's a key area of focus for my colleagues. Marialaura Martinico, a scientific documentalist working at various institutes (PDF, 622kb),provides literature research support to her clients. She discusses why Embase is so important in her daily work.
