Databases: How do I find magazine and newspaper articles? Developed by Connie Fly, COS Librarian Once you have defined your topic, the steps involved in finding information from magazines and newspapers are:
1. Select an appropriate periodical database What is a database? According to Webster’s College Dictionary a database is “a collection of organized, related data, especially one in electronic form that can be accessed and manipulated by specialized computer software.” What are the types of databases? Since we are learning about databases provided by libraries they will be our focus. COS Library Databases are not discipline specific rather they cover a broad range of subject areas. The types of databases found in the College of the Sequoias Library are: Bibliographic - A bibliographic database provides lists of source materials. Each item in a database is referred to as a record. This record describes the book or article but does not contain the complete text of the source material Examples: Library book catalog Full-Text- A full-text database provides the complete text of some if not all of the source materials Examples:
Another type of database is Numeric which can contain statistics, financial data, census data, etc. These types of databases are sometimes found on the Internet. Examples: FAOSTAT contains multilingual databases currently containing over 1 million time-series records covering international statistics in the following areas: Agriculture, trade, nutrition, etc.. The database is located on the Internet at: http://apps.fao.org/default.htm State and Country Quick Facts - This new handy reference resource from the US Census Bureau allows users to access frequently requested Census Bureau information at the national, state, and county level. The database is located at: http://quickfacts.census.gov/qfd/states/06000.html
Advantages of Databases · Ability to review your search history · Ease of starting over · Ability to switch easily from one database to another · Ability to re-execute a search in another database · Ability to mark particular records, and print, download, or e-mail results.
Disadvantages of Databases
In order to develop a search strategy it is important to understand the difference between Subject or Controlled Vocabulary Searching and Keyword Searching? Subject or Controlled Vocabulary Searches A subject search retrieves designated subject headings only, as listed in the subject headings field of each record in the database. A subject search often seems the place to start when searching for material on a topic. However, in most databases you have to know the exact subject headings for your topic (the controlled vocabulary), which may or may not be the words you are using to describe your topic.
While many subject headings are words and phrases that may be familiar to you,
many times they are not. Subject headings are assigned to database records from
predetermined lists. The predetermined list that is used depends on the
database. In the case of books and other library materials, most academic
libraries use the Library of Congress Subject Headings (LCSH) as their official
subject list. Journal indexes may use a list created by their own indexers. · Synonyms · Different spellings · Acronyms Example Question: Is human cloning likely to to be able to produce healthy and normal children? Example of Subject Search in the InfoTrac Periodical Database
A Subject Guide page appears after a successful Subject Guide search. The
InfoTrac Database lists all subjects in which the words you searched for occur
and the number of references found for each. Entries are displayed in groups and
in alphabetical order within each group. First are the entries in which your
search word(s) comes first. Next are the entries in which your word(s) comes
second, and so on. To select a Subject Guide entry, select its link. Referring to the InfoTrac figure below: A. A main Subject Guide entry leads to a list of citations B. A Subdivision link leads to another Subject Guide page with a list of specific aspects of the main entry. Subdivisions are specific aspects of the subject with which they are associated. C. A Related Subject link leads to another Subject Guide page with entries for the related subject. D. Some Subject Guide entries do not have a direct link to citations but are followed by one or more entries that start with the link "See" followed by a subject heading. The Subject Guide's thesaurus associates phrases that aren't actually indexed as subjects with subject headings that are indexed, so that even if what you type isn't in the database you'll be shown equivalent entries.

Selecting to
Keyword Searching A keyword is any word or phrase that is significant or meaningful in a topic statement. Usually, a keyword is a noun or an adjective, although sometimes a verb may also be useful. Keyword searching and search operators are available in nearly all electronic databases, so learning how they operate is essential for taking full advantage of the capabilities of this search method Before choosing keywords, you must carefully determine your information need. You must have a clear idea of your topic and what, if any concepts of the subject area you wish to focus on. Example: Is human cloning likely to be able to produce healthy and normal children?
Here the key words are: human cloning children Now carefully examine each of your significant words or phrases and consider synonyms or related terms for each.
How do I connect Keywords/Concepts in my search query? Use logical (Boolean) operators – OR, AND , NOT —to connect the words/phrases and concepts which you have listed in your Keywords above. Operators are words or symbols that are inserted between keywords to instruct the computer about the relationship between the terms within each record. The most common types of operators and symbols are:
A-B. Boolean Operators and Truncation Boolean Operator OR Within each concept connect keywords/phrase with the OR operator. The operator - OR broadens a search by specifying that any of the listed words can appear in the same article. You will normally retrieve more articles with this operator.
Boolean Operator AND Connect different keywords/concepts with the AND operator. The operator - AND will retrieve records in which BOTH of the search terms are present. You will normally retrieve less articles with this operator
Boolean Operator NOT Connect different keywords/concepts with the NOT operator. The operator NOT - we retrieve records in which ONLY ONE of the terms is present. You will normally retrieve less articles with this operator.
C. Use quotation marks "" to search for a phrase
D. Use parenthesis () to nest similar keywords/concepts together with Boolean operators.

Additional Ways to Limit your Retrieval is by:
full-text, refereed publications and by date.

3. How do I interpret an individual record citation? Look at the record citation below and notice that the record provides information about the title of the article, author, date, beginning page and text. Each of these components describes a particular aspect of each magazine or newspaper article. These aspects are called fields. These fields are the parts of each magazine record that are searched within the database.
