Determining Use
What type of information is best to use:
print vs. electronic forms of information
With easy access to electronic resources, one can
understand why students might think of the research process as beginning and
ending with computers. However, there is no "one-stop shopping" when it comes
to doing quality research. A good researcher knows how to find information in a
wide variety of formats.
Not all information is available in
electronic format
Many information sources in academic disciplines
are not yet available electronically. In addition, computerized databases have
only emerged as a research tool since the 1960's, so the bulk of information in
libraries is in a print format, as it has been since the invention of the
printing press in 1465. It is inconceivable to believe that all of this
historical knowledge will be transcribed into an electronic format.
Advantages and disadvantages of print and
electronic formats
Advantages of electronic online
searching:
- Speed. It can take minutes
(sometimes seconds) to search one or more databases while a comparable search
in print indexes takes much longer.
- Flexibility. You can link
words or search terms in a way that can never be done manually, often with
better search results.
- Variability. Truncating
(shortening) terms allows you to search for all the variations of a term. For
example, using the truncated term "colleg#" will retrieve "college,"
"colleges," "collegial," and "collegiate."
- More resources. Online
searching provides access to many more resources than are available in our
library. Books and magazine articles can be requested from the PALS databases
by using the interlibrary loan function.
- Currency. Online databases are
updated more frequently than printed sources.
Disadvantages of electronic online
searching:
- Volume. You tend to get back
an enormous number of search results, particularly if you are searching the
Internet. Here is where the importance of formulating a good search strategy
becomes essential.
- False hits. Any search in an
electronic database will frequently result in a number of false matches of your
keyword search terms. For example, a search for information on "AIDS" may
easily turn up "false" hits such as "study aids" or "visual aids."
- No cross references. Perhaps
the greatest disadvantage of online searching is the lack of cross references
that take the researcher from a poor choice of keywords to terms that will
result in a higher rate of success. This is particularly true if you make a
typographical error or spell a word wrong. No online database so far will pop
in with a spell checker to lead you to the correct spelling. And if you happen
to use a misspelled word on the Internet, you will often get hits on the wrong
word since the people who wrote the Web pages spelled them wrong in the first
place. Try looking up "mathmatics" in the Internet search engine AltaVista, and
compare the results with a search for "mathematics." AltaVista will locate
information using the misspelled word as well as the properly spelled word.
Compare this with the library's online catalog for the same keywords. The
online library catalog will locate material on mathematics only when the proper
spelling is used. What important searching principles do you think are
demonstrated by this example?
Advantages of print resources:
- Cross references. One area
where print resources are more helpful than online databases is the useful
cross references between subject headings. If your topic is broad, the "see
also" references will suggest more appropriate headings. If you haven't
picked the right subject heading, the "see" references will lead you
to the subject heading in actual use.
- History. Since many online
databases only index articles published after 1980, you will need to use print
indexes to locate older articles. If you plan to do research in the humanities,
or in history, you will most likely consult information published prior to
1980. For instance, if you wanted to do research on the formative years of rock
'n roll you would want to find magazine articles from that time period. To
locate articles on rock 'n roll from the 1950's and 1960's you would consult
print magazine indexes like Reader's Guide, or Humanities
Index, which were published in the 1950's and 1960's. Most online
databases would not be able to help you with this type of research because they
only index articles back to the 1980's.
