MAGAZINES,JOURNALS, NEWSPAPERS
There are many magazines and journals published that are related to education. Some of these journals contains articles written for educators, but are not research content.
Other journals and magazines contain helps for educators, ideas to help in teaching, or news items for educational associations. Doing educational research requires that you look
at journals that contain results of research. Again there are many journals that contain results of research. How do you access the information in these journals? Well, some research education
journals are located in the basement of this library, others are located in an online database, while others are located in neither location, but are located in other libraries.
Unlike books, the contents of journals are not available in the SE library catalog. So where are they located? They are located in magazine and journal indexes. Magazine and journal indexes assign a subject to each article in each journal indexed in the magazine and journal index. Until the 1990's most magazine and journal indexes were in paper, now they are almost all on the Internet. Some of these journal indexes on the Internet index popular magazines, other scholarly, while others are devoted to one subject area, NO Journal Index indexes every journal that is published, so they are selective.
Step One: Look in a Journal Index
A periodical index is a publication that indexes the content of periodicals. There are many different periodical indexes, some general and some subject specific. One thing needs to be made clear: There is not any periodical index that indexes every single periodical being published today. So each index is selective in what periodicals it indexes. Periodical indexes tend to index the most important or most popular or most respected or well known periodicals.
PAPER PERIODICAL INDEXES
For many years periodical indexes were published in paper, like a book. They would usually come out every few months with an update, and then come out at the end of the year with an annual cumulation. Paper periodical indexes are cumbersome to use and take some take to look at every year, but they can contain information on many valuable articles written sometimes years ago, and paper indexes are valuable places to search for topics in music, drama, art, literature and history.
| Basement | International Index An index to periodical literature in the social sciences and humanities. The index begins in 1907 and ends in 1964. |
| Basement | Poole's Index to Periodical Literature A guide to periodical literature published in 1802-1906.This is a hard index to use, so see a reference librarian. |
| Basement | Reader's Guide to Periodical Literature A general subject index to about 200 popular magazines. We have this index from 1915 to the present. |
| Basement | New York Times Index Index to the New York Times, a major national newspaper. The library has the New York Times from 1851 to the present on microfilm. The index is subject arranged. Paper indexes begin in 1929, and from 1851 to 1928 they are on microfiche. There is an online Index to the New York Times available at: http://pqasb.pqarchiver.com/nytimes/advancedsearch.html |
| Basement | General Science Index
Cites articles of at least one column each from more than 135 English-language periodicals. Coverage ranges from popular magazines to professional science journals. Approximately 3,500 records are added monthly. Biographical sketches, reports, reviews, and feature articles are included. This index includes the subjects of: astronomy, atmospheric science, biology, botany, chemistry, earth science, environment and conservation, food and nutrition, genetics, mathematics, medicine and health, microbiology, oceanography, physics, physiology and zoology. This index covers from May 1984 to 1993. |

ONLINE PERIODICAL INDEXES
In the 1980's many Paper Periodical Indexes became digitized and now most periodical indexes are online on the Internet. In this form they can still be called indexes, but they are usually referred to as DATABASES.Why use online databases?
There is a disadvantage to online databases for those who are researching topics in history or literature
Some Online Databases that the SE Library Has
| Dialog | Chemical Abstracts This database is available online through Dialog (http://www.dialogweb.com). Dialog contains many different databases and there is a cost per search and also cost per printing records. These costs vary by the database. The costs for printing records in Chemical Abstracts (File 399) is $2.75 per record printed out. Because of these costs, access to Dialog is restricted to Library personnel only. |
| FirstSearch | Article First
This database contains citations to articles that
appear in journals in science, technology, social science, business and humanities,
and popular culture. With over 15,000 journals indexed, this is one of the largest
journal databases in the SE Library's collection. It covers from 1990 to
the present, |
| EBSCOhost | Academic Search Elite Academic Search Elite provides full text for nearly 2,050 academic, social sciences, humanities, general science, education and multi-cultural journals, and abstracts for about 1330 more. Over 1,500 journals are peer reviewed. Full text backfiles go as far back as January of 1990, while indexing and abstract backfiles go as far back as January of 1984. This database is updated daily on EBSCOhost. |
| EBSCOHost, and FirstSearch | ERIC ERIC, the Educational Resource Information Center, is a very large education database that has been around since 1966. It was funded by the U.S. Department of Education until 2003, and since has been in limbo. So the database is current as of the end of 2003. IT contains over 1 million records in two types: (1) ERIC Documents, which are classroom guides, results of research not published, dissertations, manuals, results or research, and (2) Journal articles from almost 1000 journals. A new contractor for ERIC, called CSC, is currently putting 2004-2005 materials into the ERIC database. About 107,000 of the ERIC Documents from 1993-2004 are available full-text online. There is another online version at the Department of Education website, at: http://www.eric.ed.gov/ For more information on ERIC, go to the following website: http://www.se.edu/lib/eric.htm |

| FirstSearch | WorldCat
This is a database of over 40 million items that have been cataloged by OCLC libraries all over the world. It is useful as source for further information on a topic after you have exhausted all the resources at SE. |
1. Where the Databases are located
These databases are all to be found on the SE Library's Electronic Resources Page at: http://www.se.edu/lib/electres.htm
2. What EBSCOHost and FirstSearch are
The word EBSCOHost or FirstSearch to the right of the database name in the table
above indicates the name of the database vendor where you can find these databases.
If you look at the list of links on the ELectronic Resources page, you will
see the links organized by the type of database that they are. You will find
EBSCOHost and FirstSearch under the listing of databases called Periodical Databases.
When you go down the list, you will see at least two links for both EBSCOHOst
and FirstSearch. The first link is for those that are on the SE campus. Click
on that link, and you will be taken to the list of databases under EBSCOHost
or FirstSearch. The second link is the off campus link. This link is necessary
to use if you are off of the SE Campus. This link takes you to a page where
you will be asked to type in a userid or authorization number, and a password.
The userid or authorization number and password to gain access to EBSCOHost
and FirstSearch is available at the SE Library Reference Desk, and also is
on the proxy server.

3. How to narrow your search in these databases to just scholarly journals.
These periodical databases listed above index the content of both magazines and journals. When you do a search, then, you will get a list of article from both journals and magazines. How do you
do a search for just research articles? Most of the databases listed above are able to limit your search by type of publication, so you will be able to limit your search to just articles from scholarly, peer-reviewed
journals (ERIC, PsycARTICLES, PsychInfo, and PRofessional Development Collection in EBSCOHOst), or to just research articles (ERIC in FirstSearch). Limiting by this method will get rid of a lot of articles on your search results list that are from non-scholarly, magazines.
Step Four: Check to see if the the SE Library has the journal in paper

Step Five: Use InterLibrary Loan to obtain the article from another college library that has the journal that you want
1. Obtain an Interlibrary loan form from the circulation desk or go to an online InterLibrary Loan form at: http://www.se.edu/lib/illjournalreq.htm for a journal article and http://www.se.edu/lib/illbookreq.htm for Interlibrary loaning a book. 2. Fill out the form, take note that those fields of the form that have an asterisk in front of them are required fields that are needed to send the information via e-mail. Click submit after filling out the form. 3. The process of receiving something from InterLibrary loan takes about 4 days to two weeks, so if InterLibrary Loans are needed, you need to plan ahead.
When you do a research paper, the sources of your information need to be cited in your paper. There is a way to do this. There are specific rules that have been devised that explain how to do this. For journals, there are specific things that need to be in a citation. Here is an example of the parts of a journal citation using the APA style.
