FAQs

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.

Examples include:

  • 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 result 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, 394.2 KB) for more information.

Please contact sales if you are interested in using Embase at your institution. We also have individual 7-day and 30-day plans available through the Elsevier online store.

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.

Customers have 24/7 access to Embase Help, which includes training guides, workflow examples and a detailed FAQ list.

Our Customer Care team, also available 24/7, is ready to assist you by phone or email with any questions you may have.

There are three options and all will give you full access to all of the biomedical literature in Embase, allowing you to search over 30 million records from a total of more than 8,500 journals. This includes all MEDLINE content, along with over 2800 journals and 1.4 million conference abstracts not in MEDLINE.

With the 7-day plan, which is for individual use, the email alert function is not active. With the 30-day plan, which is also for individual use, you can create up to 5 automated email alerts, which will support you when performing systematic reviews for example.

With a full, annual subscription, which is IP-based access for multiple users, you get access to all of the features and content of Embase. This includes an unlimited number of automated email alerts and the full range of data export possibilities. Click here for more information on the 3 options.

You will receive two emails. One is an order confirmation with your purchase information. The other will have your registration ID and password and the instructions for registering your Embase account.

Yes. Your access to search forms and database browsing options is the same for all three options.

If you are searching for a particular term, Embase allows you to create simple searches using 'Quick Search'. If you want to perform a more complex search with more filters and limits, you have the option to use the 'Advanced', 'Drug', 'Disease', 'Device' and 'Article' searches.

You can also browse the database using the Embase thesaurus 'Emtree' or the Embase journal or author lists. Browsing is a very useful way of discovering information that you might not have realized you could access. Help in Embase has a variety of guides and videos to help get you started.

Search results include title, abstract, author and additional information, as well as drug, disease and medical device index terms identified from the full-text of articles. A link is provided to the full-text article — the ability to access full-text articles depends on whether the article is open access and therefore freely available or if you have a subscription to the journal in which the article is published. In cases where you do not have a subscription to the journal, the full-text link will redirect you to the publisher’s page where you may purchase the article.

Yes. Both the 7-day and 30-day plans are designed for individuals rather than organizations. If a large team or organization needs access to Embase, you should consider the full subscription. Click here for more information on the available packages.

Yes. There is a comprehensive set of guides and videos in the Embase Help section, accessed from within the product. We will also send you links to helpful guides, webinars and instructional videos via email when you purchase Embase.

In the unlikely event that your payment cannot be processed, please do not resubmit the order. Contact the Help Desk at cs@elsevier.com and provide the Unique Order Number along with a valid credit card number and correct billing information.

If you have contacted Elsevier or placed an order and not yet received a response, please check your ‘Junk’ or ‘Spam' folder. It is possible that Elsevier is not on your ‘safe sender’ list and any response sent by Elsevier is automatically directed to this folder by your email system. If the email has indeed been delivered here, you can add the relevant Elsevier email address (es) to your address book and/or add Elsevier to your 'safe-senders' list, so that all future correspondence from us will be directed straight to your inbox.

If the email from Elsevier is not in your ‘Junk’ or ‘Spam’ folder or have any further questions, please Contact Us.

If the registration ID has NOT been redeemed and Embase has NOT yet been accessed, then it is possible to refund the order. Prior to confirmation of the purchase, customers are prompted to carefully check their order as Elsevier cannot offer refunds based on mistakes made in the order.

You can download a complete list of the journals in Embase here (XLSX, 754.1 KB).

You can also see a list of the journals in Embase within the interface. Go to the ‘Browse’ dropdown menu and choose ‘Journals’. This gives you a complete alphabetical list of the journals (excluding the journal titles covered in Embase.com but indexed exclusively by MEDLINE). You can use the alphabetical navigation at the top of the list to move between letters.

You can download a complete list of the conferences covered in Embase here (XLSX, 604.8 KB).

Over 2800 journals are unique to Embase and 3000 journal titles are covered by both Embase and MEDLINE. Both of these journal types are indexed by Embase using Emtree. 2500 journal from MEDLINE, which is produced by the U.S. National Library of Medicine (NLM) and forms the core of PubMed, are not indexed by Embase using Emtree, but are instead indexed using the MEDLINE thesaurus MeSH.

Indexed MEDLINE records are delivered to Elsevier on a daily basis, and are incorporated into Embase after de-duplication with records already indexed by Elsevier to produce so-called MEDLINE-unique records. These MEDLINE-unique records are not re-indexed by Elsevier. However, their indexing is mapped to Emtree terms used in Embase to ensure that Emtree terminology can be used to search all Embase records, including those originally derived from MEDLINE.
