As a rule of thumb you should always select a minimum of two or three databases. Why is this important? All research, even on a specific topic, are not all published in the same source and not all sources in a discipline are all located in the same database. The goal of doing a literature review is usually to find the most relevant (and often times the most current) primary research studies that provide data to help you answer or prove/disprove your research question. In order to do this you never want to limit yourself to using articles from just one journal or even journals/sources from just one database.
As you will discover in this section and in doing your literature review, there are different types of databases and many different types of sources. Databases may differ from each other in what disciplines they cover, what subjects within a specific discipline they cover, what type of sources they provide access to, the specific sources they provide access to, and whether they provide online access to the actual item (full-text article, book, video, et cetera) or provide you just with the citation so that you can request the item through your library. Check out the table below for an example. When searching in multiple databases, you may encounter some duplication of items, but there will also usually be a lot of unique items that are only found in one database and not the others.
I implemented my initial search strategy of (bull* or aggress* or teasing) and (gender or boy* or girl*) and ("middle school*") across the 4 databases listed below, without applying any database limits. In the table below is what I found so you can start to see the differences. When I looked at the top results in each database, there was only 1 article that was found in 2 of the databases and 10 of the articles were unique.

When thinking about the types of databases, one aspect is how many disciplines does it cover.
A Subject Database focuses on one discipline or sub-discipline. ERIC, Education Source and Proquest Education Database are all subject databases focused on the discipline of Education as a whole. Click on their respective tabs above to learn more about each of these subject databases.
A Multi-disciplinary Database focuses on at least two different disciplines, but often covers many more. A great multi-disciplinary database is Academic Search Ultimate, covering 21 disciplines. Click on the Academic Search Ultimate tab above to learn more about this multi-disciplinary database.
Another aspect to consider is its content level and the type of sources it provides access to.
Content Levels:
Research tip: Look at the criteria for your assignment (whether for school or work) in identifying any requirements as to the types of sources you must use or can't use to help you select a database as well as in forming your search strategy.
ERIC stands for the Education Resources Information Center. It is a subject database focused on the field of education. It provides access to two different versions of the ERIC database.
You can connect to ERIC using the link below or from the Research section of the Library website.
ERIC provides access to information from journals included in the Current Index of Journals in Education and Resources in Education Index. Journals range from academic/scholarly, peer-reviewed, trade publications and popular magazines in the field of Education. It also contains a collection of ERIC documents that include books, conference proceedings, dissertations, education reports and more. The content dates from the present back to 1966.
The database distinguishes articles from other formats by assigning an ERIC number to each item (in parantheses) which is placed at the end of its citation information in your results list. The number always starts with an EJ to indicate that it is an ERIC journal article or ED to indicate that it is an ERIC document. Documents are any format except journal articles. Many of the peer-reviewed, academic/scholarly journals and other online sources provide full-text access in ERIC (EBSCOhost), but if the database indicates that it is only available on microfiche the library has the microfiche collection available in the Periodicals Collection, 2nd floor. If you need an item that is on microfiche or in a print journal, connect to ILLiad (refer to the "Can't Come to the Library?" section for details on ILLiad) to request it. The item will be scanned into a PDF document and posted into your ILLiad account where you can download it.
Special Limit & Search Options - help you refine your search
Most of the research databases, including ERIC, provide limit options that you can use to help narrow your search. Most databases have at least these two limits:
ERIC and many of our other databases provide additional limits you may want to use such as:
Limits unique to ERIC:
ERIC and many of our databases also offer special searching functions which can be really helpful. When you are in a new database click on Help to see what is available. A couple of the functions to look for are:
Thesaurus
The ERIC database provides a Thesaurus. This is an extensive alphabetical list of terms encompassing a wide range of topical subjects in the database. The Thesaurus is arranged in a hierarchy that permits searching various levels of detail from the most general level to more narrow levels to find the most precise concept. Thesaurus entries include 'Use', 'Broader Terms', 'Narrower Terms', and 'Related Terms'.
The authority file provides flexibility in searching. As an alternative to the keyword search mode, the authority file enables the user to search by subject and to combine one or more terms to create more defined searches. Select the Alphabetical option to position the authority file list to the term(s) entered. Select Relevancy Ranked to order search results according to relevance.
You can browse the Thesaurus by clicking on the link in the upper-left corner of the ERIC database screen. This is a great way to find words or phrases to use as your search terms.
Education Source is subject database covering scholarly research and information relating to all areas of education. Topics covered include all levels of education from early childhood to higher education, and all educational specialties, such as multilingual education, health education, and testing. Education Source also covers areas of curriculum instruction as well as administration, policy, funding, and related social issues. The database provides indexing and abstracts for more than 2,300 journals, as well as full text for nearly 1,400 journals. This database also includes full text for nearly 550 books and monographs, and full text for numerous education-related conference papers.

ProQuest® Education Database gives users access to around 900 top educational publications, including more than 600 of the titles in full text. It offers complete information on hundreds of educational topics, including full text and images from journals such as:
Image articles include all the charts, tables, diagrams, and other graphical elements often used to enhance the editorial value of articles that focus on education topics.
ProQuest Education Database contains journals that cover not only the literature on primary, secondary, and higher education but also special education, home schooling, adult education, and hundreds of related topics with subject coverage on:

Many databases include an added function to help you cite the sources you use. In most cases, you won't see the citation tools until you click on either the full-text link at access the item or click on the item's title in the results list (this takes you to a Detailed Record page that provides additional information about the item and its source). Whenever you take a citation from a database, ALWAYS check it for errors. Here is what to look for:
In databases such as ERIC, Education Sources and Academic Search Ultimate databases that we get via EBSCOhost, once you are in the full-text or on the Detailed Record page a Tools bar will appear on the right of your screen. In the middle of the options you have several choices:
In databases from Proquest such as the Proquest Education Database, you can select one or much items in your results list and then click on the "Cite option in the top right-hand corner (between your search box and your results list). This will pop-up a box showing the items you listed, just click the dropdown menu and select APA 6th edition and click the change button. You can then copy paste those citations into your reference list. As with the EBSCOhost databases, you can also access the "Cite link when you are are in the full-text or on the Detailed Record page (right, upper corner of your screen).
