.MP stands for multi-purpose. If you enter an Advanced search without specifying a particular field, Ovid defaults to a .MP search which searches several fields at once. The fields searched by a .MP search may vary, but in general a .MP search looks in the Title, Original Title, Abstract, Subject Heading, Name of Substance, and Registry Word fields. When using .MP, the search often looks for single words in phrase-indexed fields. Phrase-indexed fields can only be searched with their exact phrases. So .MP is a technique to look at single words in these fields when broader searches are needed.

Here is an example of what fields are searched when using .MP in Embase:

I am not an Ovid administrator and I forgot my Ovid username and/or password.

The subscribing institution determines how to distribute user names and passwords for their Ovid database subscriptions.

If you are trying to access Ovid from outside of your institution you will need to contact your local librarian, or in some cases, your network administrator. They will be able to provide you with the appropriate login information.

Please note that your personal account login (PIN) is different from the institutional login to the Ovid subscriptions. If you have forgotten your PIN account access please contact [email protected].

Where can I find a list of the journals indexed in the EMBASE database?

Because of the high level of maintenance required to keep journal lists up to date, Ovid relies upon our Information Provider partners to provide a list of journals indexed in their databases.

A list of the journals and conferences indexed in the EMBASE database is available at this URL:

Where can I find Ovid Training Schedules?

Please visit our Training and Documentation site for a list of Web-based Training Sessions, Tutorials for Ovid, and Training Presentations.

Training sessions are also available in Spanish, Italian, Portuguese and Chinese.

The correct approach for limiting a result set by date range depends on two major factors, the actual span of time of interest and the particular database or databases from which the search results were derived.

Limiting by a range of complete years

In the simplest cases, results can be easily limited to a range of completed years by applying the Publication Year Limit.

In the example below (from Embase query), I want to limit my result set from a keyword search for "high throughput screening" to those results with publication dates between 2014 and 2015.

Result set #2 (below) shows the 6082 results, a subset of result set #1, which had publication dates of 2014-2015:

This approach can even be used when limiting search results derived from multiple databases.

Limiting by portions of years

A more complex scenario involves limiting result sets to portions of years. This case is more challenging than the previous example because the Date of Publication field in Ovid databases consists of non-standard values supplied by publishers, such as 15-January-2010 or Jan-Feb 2010 or Winter 2010. This variability of data renders that field unsuitable for either searching or limiting by a date range more precise than Publication Year. Other fields must, therefore, employed, and the choice of field will vary from one database to another.

Let’s repeat the Medline search above, limiting a result set on "high throughput screening" to a date range. But this time, instead of limiting by a range of completed years, I will limit by the First Quarter of 2010.

Note that in step 2, above, I needed to insert a command-line statement to Limit result set #1 to those records with Date Delivered (dd) between 1-January-2010 (20100101) and 31-March 2010 (20100331). The definition of the Date Delivered (dd) field and its data format YYYYMMDD are listed in the Embase Database Field Guide. This method can be used to limit to any range of dates.

An additional step may be necessary to eliminate old publications that may have been revised or reloaded during the specified time period. I can eliminate those publications from earlier years by once again applying a Publication Year limit. Notice below that some (8) of the results entered into Embase between 1-Apr-2009 and 31-Mar-2010 were indeed from earlier years.

As is clear in the examples above, each database will have its own best practices for limiting by date range.

Is there a complete list of the Embase subheadings and their codes?

A list of the Embase Subheadings and their codes follows.

Subheadings, or "link terms" are qualifiers added to EMTREE subject headings to refine their meaning. Terms such as "adverse drug reaction" or "drug toxicity", when combined with an EMTREE term, give a very precise idea of what an article covers (Ex: arthritis/dt [Drug Therapy])

The Floating Subheadings (FS) field contains the 2-letter subheading codes, such as "AN" for drug analysis. For example, to find any records that contain the subheading, Drug Therapy, enter this Ovid search statement:

dt.fs

To link a subheading to a subject heading, enter an Ovid search statement like this:

arthritis/dt

How do I create an Alert?

Once you access Ovid, choose the database you want and create a search to be used as an Alert. Next, click the “Save Search History” button. At this point, you are prompted to create a Personal Account. You enter a username and password of your choice. (This has nothing to do with your Ovid login, or any other username/password you have used previously.) This is completely user-defined. After completing the Personal User Account setup, the following screen is displayed. When you select AutoAlert from the pull down menu under Type, you will see a form with options allowing you to customize your Alert.

The third choice in Report Type – “Email includes records only” is what a typical AutoAlert would contain (just the records). However, the additional choices give you the ability to be sent a link to your search history in Ovid, along with your records. The second choice “Email includes records, a Titles Display Link, and a link to each records’ Fulltext or Complete Reference Display” is the choice that gives you everything.

Once you have entered the information to create your Alert, you are returned to the search screen. If you click on the “Saved Searches” button, you can view the Alert that you just created. Click on the box next to the name of the Alert to select it and you can then run (or delete, copy, rename, display, edit, or email a jumpstart) the Alert.
