Frequently asked questions
Purchasing and implementation
There are three options, and all give you full access to the biomedical literature in Embase. Search over 44 million records from a total of more than 8,200 journals. This includes 99% of MEDLINE journals, and 3,000 journals and 4.7 million conference abstracts not in MEDLINE.
With a full, annual subscription, which is IP-based access for multiple users, you get access to all the features and content of Embase. This includes an unlimited number of automated email alerts and the full range of data export possibilities. Contact sales to discuss pricing.
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.
Yes. Your access to search forms and database browsing options is the same for all three options.
For a simple search on a particular term, use Quick Search. For a more complex search with more filters and limits, you can search by: Advanced, Drug, Disease, Device and Article.
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.
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.
For the 7-day and 30-day package, what do I do if my payment cannot be processed?
In the unlikely event that your payment cannot be processed, please do not resubmit the order. Contact the Help Desk(打開新的分頁／視窗) and provide the Unique Order Number along with a valid credit card number and correct billing information.
No, you don’t need to register for the store again. However, after you purchase your plan, you will need to register to use Embase. You will receive your Embase registration information via email.
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 senders list and any response sent by Elsevier is automatically directed to this folder by your email system. If the email has 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 you 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.
Yes, you can renew or upgrade your plan without having to register in Embase again or create a new user profile. After your final session of your 7-day or 30-day plan ends, you cannot log in again. If you attempt to log in, you will be prompted with message indicating your access is denied.
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 sales.
Embase, MEDLINE and Scopus
Embase has significant content that is not available in PubMed/MEDLINE. Also, Emtree indexing makes even information shared by the two databases uniquely discoverable in Embase.
Over 3,200 journals are unique to Embase and ~3,000 journal titles are covered by both Embase and MEDLINE. Both sets are indexed by Embase using Emtree. 2,500 journals from MEDLINE are not indexed by Embase using Emtree, but are instead indexed using the MEDLINE thesaurus MeSH. These indexed MEDLINE records are delivered to Elsevier daily. After deduplication, they are incorporated into Embase to produce “MEDLINE-unique records.” These MEDLINE-unique records are not re-indexed by Elsevier. However, their indexing is mapped to Emtree terms. This way, Emtree terms can be used to search all Embase records, including those from MEDLINE.
Scopus searches focus on abstracts and citations, while a search in Embase provides additional insights from its structured full-text indexing. 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 those indexed using the Emtree term "heart infarction.
"In addition, Embase subheadings are not available on Scopus, so searches cannot be narrowed down the same way. For example, it is not possible to limit drug searches to records focusing on adverse effects.
