Finding
Good Information Resources: Primary v. Secondary
2.1
Successful Searches start with knowing your information sources
One of the first steps to take in a successful search is to determine
what type of information you need and where to find that type of
information. Two main types of sources are Primary and Secondary
sources.
Primary
sources capture a first-hand experience
in some way; Secondary sources analyze or reflect on primary sources,
or give an indirect account of events. Primary sources might include
informal personal accounts, like diaries or personal interviews,
or more public, formal accounts of an event, like a log-book or
news-reporting. Some examples are noted below.

|
Primary
Sources: offer a first-hand account of events
autobiographies,
diaries, letters
photos, maps, plans
newspaper articles on direct account of events
science experiments/data
official records, memos, logs

Maritime Museum) |

|
Secondary
sources: provide a second-hand or interpreted account
of events
biographies (Pictured: biography by Diana Preston)
historical books and articles
literary criticism articles
articles discussing experiments
expository books |
Secondary
sources are often a bit easier to trackdown, because there is generally
only "one" primary source or original record. Primary
sources might be re-produced in a book, in a journal or on the web,
but you might also consult with your librarian to find archival
material or a collection that specializes in housing primary sources
for your topic.
