Searching
Databases
Each database interface is
a little different from the next, but there are plenty of things they
have in common. Once you learn to look for these common features, you'll
be able to approach any new database interface with confidence.
The most obvious thing to
look for is the search box. This is the box in which you'll type in
your search terms. There may be a single box in which you type everything,
or there may be an option for an "advanced search" which has multiple
boxes. Choose whichever you prefer.
The next thing to be aware
of is the searching techniques which the database supports. This will
vary a little from database to database, but most have the following
features in common:
- Boolean Operators (and,
or, not). Note that in some databases, these need to be in capital letters
or they will be ignored as stopwords. This is true in the Britannica
Online and in many of the free government databases. If you are not
sure, put your Boolean Operators in all caps just to be safe.
- Nesting. Any database which
supports Boolean Operators should also support nesting. Use parentheses
to set off "or" phrases.
- Phrase searching. In some
databases, phrases are automatically treated as such. In others, you
may need to use quotation marks or proximity operators to indicate that
they are phrases. Check the help files or ask at the reference desk
if you are not sure how to do this for your database.
- Truncation and wildcards.
Most databases use the asterisk (*) as the truncation symbol, but there
are a few exceptions. Lexis-Nexis uses the exclamation point (!). Dow
Jones uses the dollar sign ($). DIALOG uses the question mark (?).
- Field searching. The methods
for doing this vary from database to database, but it is almost always
available in some form or another. Look for a pull-down box for various
fields, and if that is not available, check the help files or ask at
the reference desk.
- Limiting features. Look
for date range, record type, language and other limiters to help narrow
your search.
For an introduction to
the use of the above searching techniques, see Show
me how to improve my searching techniques.
Once you have a reasonable
number of records (called citations), you can go through them and
select the ones which most interest you. Most databases allow you
to "mark" records so that you can go back and print, e-mail, or download
just the ones you want after you are finished looking at them. Look
for a small box to click with your mouse next to each record. (Two
notable exceptions: Lexis-Nexis does not offer marking capability,
and DIALOG web only saves the marking from one screen at a time, so
you will need to print as you go.) Once you have marked all the records
you want, look for a button saying something like "show marked records."
This should display only the ones you have marked. At this point,
look for printing, e-mailing, or downloading options.
IMPORTANT: PLEASE LIMIT
YOUR CITATION LIST TO UNDER 50 RECORDS BEFORE YOU BEGIN TO LOOK THROUGH
THEM. SOMETIMES STUDENTS SPEND HOURS LOOKING THROUGH HUNDREDS OF RECORDS,
ONLY TO HAVE THE COMPUTER CRASH BEFORE THEY CAN PRINT OUT THE ONES
THEY'VE MARKED. WE DON'T WANT TO SEE ANY MORE EXHAUSTED TEARS FROM
THIS HAPPENING. LIMIT YOUR SEARCH APPROPRIATELY. THAT'S WHAT ALL THIS
TECHNOLOGY IS FOR. IF YOU NEED ASSISTANCE IN NARROWING YOUR SEARCH,
PLEASE ASK AT THE REFERENCE DESK.
Only a few databases have
the full text of articles online, and in many of the ones that do
have it, not all of the articles within the database are full text.
Don't limit yourself to articles which are full text online. You will
be cheating your research if you do. Some of the best information
is still only available in print or microform journals. If you find
a citation which interests you, see How do
I find journal articles on my topic? for steps to take in
order to see if Furman has it, and where to find it.
