[email protected] (OVFT) Database Guide

[email protected] is the second generation of Ovid Full Text, which combines all the capabilities of Ovid Full Text Collections with several important features and functions. The database is an aggregate of hundreds of scientific, technical, and medical journals from over 50 publishers and societies. While the Ovid Full Text Collections are subsets of journals combined for local access, [email protected] is and aggregated online database of all Ovid journals, with each journal available by individual subscription. Some of the benefits of [email protected] are:

  • Custom Full Text Limit. With the purchase of any of Ovid's Full Text journals, you gain access to all the bibliographic citations, references, and abstracts in the [email protected] database. You can search the entire database of bibliographic citations, or you can limit your search to the full text journals to which your institution has subscribed.
  • Seamless Linking. Each [email protected] title is linked to other [email protected] titles, and to bibliographic databases on Ovid Online such as MEDLINE, CINAHL, and APA PsycInfo®. Bi-directional linking allows you to start your search in a bibliographic database and link to the full text in [email protected], or link from [email protected] to citations in bibliographic databases. Additionally, you can link from references in an article to other full text articles. Within the Full Text display, hypertext features allow you to display an outline of the document and move immediately to a selected section, and link from cited references in the text to the complete reference.
  • Easy Browsing. Browsing through journals in [email protected] is easy and intuitive. You can browse through the journals by title, or by journal subject, where the journals are grouped according to subject areas.
  • Comprehensive Coverage. We are including additional sections of the print journals in [email protected], such as classified advertisements and announcements, making the database not only useful for conventional research, but for recreational and professional browsing as well. Journal-specific information is available through About This Journal. This feature provides information such as the publisher-provided journal description, usage statement, and instructions for authors.
  • Limits. In addition to the limits already available in Ovid Full Text, [email protected] features a limit to articles with graphics, a limit to one or more journal subsets, and a limit to articles with references.
  • Enhanced Searching. Because [email protected] is available in 100% SGML, every word of every article in [email protected] is searchable, including references and graphics captions. Searching the [email protected] Fields describes the searchable fields and provides at least one example for each.

Journals come from many prominent publishers.

When printing a full text article, the default graphic size is full size. The graphic-size option is available through the Full Text Manager at the end of each article. Graphics can be printed in full, medium, or small (thumbnail) size, or omitted entirely.

Access and Availability
  • Search results cover the entire [email protected] database. You receive unlimited access to every title in the database for bibliographic citations, references, abstracts and the tables of contents. Your access to bibliographic content is only limited by number of Ovid licenses.
  • Your institution subscribes to a full text journal or journals from the [email protected] database and purchases a license for an appropriate number of concurrent users for each full text journal.
  • You receive customized access to full text based on subscriptions and licenses.
  • If you want to limit your search to full text articles while within [email protected], use the Full Text limit described under Limits.
  • Paygo users can access the full text of all journals.
  • Selected journals include access to critical content before it appears in a printed journal issue as part of the Publish Ahead of Print feature.
Coverage and Content

Ovid Full Text Collections have always included items such as research articles, book and other media reviews, editorials, and letters to the editor. With [email protected] we have included classified advertising, announcements, abstracts of symposia, calendars, and corrections. You easily can find these citations by searching on one of the new Publication Types on the Limit page: advertisements, announcements, meeting abstract, and corrections. The content is licensed by the publisher, and therefore varies somewhat from journal to journal.

[email protected] is updated daily to ensure access to the most recently published issues. [email protected] offers coverage from 1996 to the present for many journals, and the coverage of some journals dates back as far as 1993. A few journals begin at other points. Refer to the Ovid HomePage for a complete listing of journals and start date, or find individual journal start dates in "About this Journal".

NOTE: This guide is universally intended for all [email protected] subsets such as APA PsycArticles® and [email protected] This includes the following segments: OVFT, YROVFT and PAOVFT (subscribers only).

Publish Ahead of Print

Ovid’s PAP Full Text provide users with online access to critical content as soon as the material is ready for release and before it appears in a printed journal issue. All [email protected] PAP Full Text has been peer-reviewed and accepted for publication.

A special PAP issue displays at the top of the issue list for participating journals. Users click the Table of Contents link for the PAP issue, review entries in the TOC display, and access PAP Full Text available for that journal. When PAP Full Text becomes available in print, Ovid removes the record from the PAP issue.

Publish Ahead of Print is only available for select journals.

Articles in any pre-publication stage can change significantly before final publication. Because Ovid’s PAP articles present data that is in-process toward final publication, their statements, opinions, and information may contain errors in facts, figures, or interpretation. With this in mind, apply responsibly any information gained from [email protected] PAP articles. Accordingly, the publisher, editors, authors of PAP articles, and their respective employees accept no liability for consequences of any inaccurate or misleading data, opinion, or statement.


Ovid provides an outline for every article, so you can move from section to section with the click of a mouse. Hypertext links within each article-structured abstract links, reference links, context links, and figure links allow you to jump immediately to the relevant section or graphic.

Citations within the document text are linked to the Reference section, enabling you to quickly check a reference. A context link in each reference allows you to easily move back to your original place in the document.

From any full text article, you can link to journal information in About This Journal or to the issue's table of contents.


Link from bibliographic databases to full text: Start your search in a powerful bibliographic database, like MEDLINE, APA PsycInfo®, or CINAHL, and link seamlessly to full text articles.

Link from full text to full text: References in an article link to other full text articles so you can follow an author's research, trace the history of a topic, or find similar information.

Link from full text to bibliographic databases: References in full text articles link to bibliographic citations in databases such as MEDLINE, CINAHL, and APA PsycInfo®.

Browsing through Journals
Browsing through journals is familiar to most researchers. Accordingly, browsing functionality in [email protected] has been improved to make the process easier and more intuitive. Users can browse by journal name or subject, and can link from the Contents display to the bibliographic record or full text of each article.
Browsing by Subject

If you know you want articles on a certain topic but you're not familiar with the available literature, journal browsing can help. Given the large number of journals in the database, Journal Subsets were created to help you find the most relevant journal titles to your area of interest. Each journal in [email protected] is classified in at least one of five categories:

  • Clinical Medicine
  • Behavioral & Social Sciences
  • Life Sciences
  • Nursing
  • Physical Science & Engineering

Journal Subsets are further divided into subject categories. For example, "Clinical Medicine" contains subject categories such as "Anesthesiology" and "Radiology."

Each journal is assigned to one or more Journal Subsets based on subject matter. By clicking the Browse Journals button, you access a hierarchical display of journal subsets and their subject categories. Choose your area of interest, and then you can browse through a list of journal titles, or a list of specific issues. Alternatively, you can limit your search to one or more journal subsets. (The medical categories were reviewed by clinical professionals to ensure that they correspond as closely as possible to relevant areas of medical practice.)

Note: journals are classified by journal name and description, not by article content.

Browsing by Name:
The Browse Journals button allows you to browse an alphabetical list of journal titles, to locate a particular journal. From here, you can link from a journal title to the relevant subject category, so you can find other journals in the same subject area.
About This Journal

The "About This Journal" feature provides masthead information about each journal online, including:

  • journal description
  • coverage information
  • publisher
  • frequency of publication
  • usage statement, including copyright information and restrictions (The copyrights are held by the respective journals, not by Ovid Technologies.)
  • instructions for authors

The About This Journal button is available from the Table of Contents, full text article displays, and the Browse Journals display. The "About This Journal" section displays as a full text document that can be searched, printed, saved, or emailed.

[email protected]

[email protected] is a subset of the larger [email protected] database and is limited to only the journals to which your institution subscribes. [email protected] was created for situations when a user wants to see only the citations to which they have access. It provides all of the basic functionality of [email protected], including 100% searchability, seamless integration with databases, and the ability to browse by journal and by subject.

[email protected] is a single database that contains the Ovid Full Text and graphics of every full text journal offered by Ovid. Regardless of the number of subscribed [email protected] titles, every [email protected] subscriber gets access to all of the Tables of Contents, Bibliographic citations, Abstracts, and references in the entire database. With [email protected], however, users only obtain these results for subscribed to journals.

Index Browsing
While you can Browse the Tables of Contents for Journal titles and their issues, [email protected] does not allow Browsing of individual field indexes. Therefore when you Search Fields the Display Index button does not appear and the root command is unavailable.
[email protected] FAQ
Do you need to change existing full text Jumpstarts to [email protected]? (For Administrators)
This is optional for customers who maintain both [email protected] and [email protected] databases. If you do wish to redirect existing jumpstarts from [email protected] to [email protected], simply change their segment name, such as &D=yrovft.
Do you need to resave your Save Searches?
No. You may run your Save Searches from any database.
Do you need to reset your AutoAlerts (SDIs) in [email protected]?
AutoAlerts are database specific.

This field is a Table of Contents field.


Text Word [Word Indexed]
urinary tract infection.tw.


The Text Word (TW) field searches the Title (TI), Abstract (AB), Caption Text (CT), as well as the Full Text (TX) fields.


Full Text [Word Indexed]
unilateral cleft lip.tx.


The Full Text (TX) field contains the complete document text. This field allows you to retrieve all documents with any mention of your search term. Because authors are more likely to use synonyms in the text field, or often include relevant information on a topic that is secondary to the main topic of the paper, you will find much more complete results by using the full text instead of just the title and abstract.

Note: TX searches only the full text part of the article, and only the parts of the full text that are not included in other fields. All bibliographic information, such as title and author, abstract, references, and caption text are all indexed in other fields. Therefore, they are not searchable in the TX field.

Stopwords, which include commonly occurring words such as "of" and "the" display in the documents but do not appear in the Full Text index.

Advanced Searching
You can use special search syntax listed below to combine search terms or strategically develop a search. Full documentation is provided in the Advanced Searching Techniques section of the Online Help.
Operator Syntax Search Example Sample Results
OR x or y heart attack or myocardial infarction "Chronic traumatic aneurysm of the left main coronary artery causing myocardial infarction."


The OR operator retrieves records that contain any or all of the search terms. For example, the search heart attack or myocardial infarction retrieves results that contain the terms heart attack, myocardial infarction or both terms; results are all inclusive. You can use the OR operator in both unqualified searches and searches applied to a specific field.
AND x and y blood pressure and stroke "Treatment of high blood pressure in acute stroke"


The AND operator retrieves only those records that include all of the search terms. For example, the search blood pressure and stroke retrieves results that contain the term blood pressure and the term stroke together in the same record; results are exclusive of records that do not contain both of these terms. You can use the AND operator in both unqualified searches and searches applied to a specific field.
NOT x not y health reform not health maintenance organizations "the rhetoric and reality of health reform in New Zealand"


The NOT operator retrieves records that contain the first search term and excludes the second search term. For example, the search health reform not health maintenance organizations retrieves only those records that contain the term health reform but excludes the term health maintenance organizations. In this way, you can use the NOT operator to restrict results to a specific topic.
You can use the NOT operator in both unqualified searches and searches applied to a specific field.
Adjacency (ADJ) x y blood adj pressure "Twenty-four hour ambulatory blood pressure monitoring"


The Adjacent operator (ADJ) retrieves records with search terms next to each other.You do not need to separate search terms manually by inserting ADJ between them, because when you separate terms with a space on the command line, Ovid automatically searches for the terms adjacent to one another. For example, the search blood pressure is identical to the search blood adj pressure.
Defined Adjacency (ADJn) x ADJn y physician adj5 relationship "Changes in physician-patient relationship"


The defined adjacency operator (ADJn) retrieves records that contain search terms within a specified number (n) of words from each other in any order. To use the adjacency operator, separate your search terms with ADJ and a number from 1 to 99. For example, the search physician adj5 relationship retrieves records that contain the words physician and relationship within five words of each other in either direction. This particular search retrieves records containing such phrases as physician patient relationship, patient physician relationship, or relationship of the physician to the patient.
Frequency (FREQ) x.ab./FREQ=n blood.ab./freq=5 "Is the accuracy of blood pressure measuring devices underestimated at increasing blood pressure levels?"


The frequency operator (FREQ) lets you specify a threshold of occurrence of a term in the records retrieved from your search. Records containing your search term are retrieved only if the term occurs at least the specified (n) number of times. In general, records that contain many instances of your search term are more relevant than records that contain fewer instances. The frequency operator is particularly useful when searching a text field, such as Abstract or Full Text, for a common word or phrase.
Unlimited Truncation ($) x$ disease$ "identify genes responsible for diseases and traits"


Unlimited truncation retrieves all possible suffix variations of the root word indicated. To apply unlimited truncation to a term, type the root word or phrase followed by either of the truncation characters: $ (dollar sign) or * (asterisk). For example, in the truncated search disease*, Ovid retrieves the word disease as well as the words diseases, diseased, and more.
Limited Truncation ($) x$n dog$1 "renal function in healthy dogs"


Limited truncation specifies a maximum number of characters that may follow the root word or phrase. For example, the truncated search dog$1 retrieves results with the words dog and dogs; but it does not retrieve results with the word dogma.
Mandated Wildcard (#) xx#y wom#n "serum homocysteine levels in postmenopausal women"


Searching with a mandated wildcard retrieves all possible variations of a word in which the wildcard is present in the specified place. You can use it at the end of a term to limit results to only those that contain the word plus the mandated character. For example, the search dog# retrieves results that contain the word dogs, but not those that contain the word dog, effectively limiting results to only those that contain the plural form of the word. The mandated wild card character (#) is also useful for retrieving specialized plural forms of a word. For example, the search wom#n retrieves results that contain both woman and women. You can use multiple wild cards in a single query word.
Optional Wildcard (?) xx?y colo?r "Hair changes. Age has effect on color, thickness."


The optional wild card character (?) can be used within or at the end of a search term to substitute for one or no characters. This wild card is useful for retrieving documents with British and American word variants since it specifies that you want retrieval whether or not the extra character is present. For example, the optional wild card search colo?r retrieves results that contain the words color or colour. You can use multiple wild cards in a single query word.
Literal String ("") "x / y" "go/no-go"

"Single trial-based prediction of a go/no-go decision in monkey superior colliculus"

"n" "3".vo

"Nature Clinical Practice Cardiovascular Medicine. 3(12):689-92, 2006 Dec."


Quotation marks can be used to retrieve records that contain literal strings, when the string includes special characters, such as a forward slash (/).

Quotation marks can also be used to retrieve records that contain numbers that may otherwise be confused for earlier searches. In the example, a search for 3.vo would limit the string from your third search in your search history to the volume field. By including the number in quotation marks, the search will retrieve documents with a 3 in the volume number.
