During the course of your research, it is important to consult a variety of sources, including print and digital. On-line resources are quick and convenient in that they can be accessed outside the library, but they do not represent the complete range of information available in any discipline. Many of the rich resources owned by the Library, both primary and secondary, are available in print. A librarian can help you locate appropriate resources for your topic.
Good researchers don't ignore a possible location or lead. Some sources you discover may not be available in Dickinson's collection. When beginning the research process, be sure to build in enough time to order materials through Interlibrary Loan.
A good researcher is defined by the willingness and ability to follow leads and being able to quickly evaluate a source for its reliability and usefulness. Clues to important and reliable information come from many places. Secondary sources are often good places to start the reserach project, as their footnotes and bibliographies can provide you with leads to primary sources and other important secondary works.
Primary and Secondary Resources
A primary source is an account by an eyewitness or the first recorder
of an event - or documents produced at the time an event occurred.
A primary source may be printed or electronic material and can include
diaries, letters, memoirs, personal papers, public documents, field
research reports, minutes of meetings, news footage, newspaper articles,
speeches, oral histories. Primary source material can also include
creative works such as poetry, music, or art, and artifacts such
as pottery, furniture, and buildings. Dickinson College owns primary
material in fields such as Native American and scientific history,
and the history of Dickinson College. The Library also has many
indexes and databases which will help you locate primary material.
A secondary source is a document which is derived from, or based
on, study and analysis of primary sources. These are works that
are not original manuscripts or contemporary records, but which
critique, comment on, or build upon these primary sources. They
interpret and analyze primary sources and provide the background
necessary to understand the primary sources. A secondary source
may be printed or electronic material and can include reviews, criticism,
editorials, analyses, encyclopedias, textbooks, histories, and commentaries.
Most scholarly journal articles are secondary sources which provide
analysis, interpretation, or evaluation.
How to Start
Looking for Sources
Keywords
Developing a list of keywords for your project is vital for
your bibliographic search, for your note taking and for shaping
your final paper. A keyword is simply an important word or
short phrase relating to your research. Keywords can be a
person's name, a book title, a place, an organization or a
subject. You can often use keywords to conduct a search of
the library's catalog, electronic databases, or printed indexes.
As you begin to reseearch your topic, you will discover additional
keywords that describe your subject.
Subject Headings
A subject heading is a specific word or phrase used to find and
organize books and articles by topic. Subject headings are different
from keywords in that they are specific terms assigned to a subject
by an organization. For example, the Library of Congress supplies
subject headings for books owned by Dickinson College (and other
libraries), and the company that provides the MLA database supplies
subject headings for the articles indexed in that database.
These subject headings, also known as subject descriptors, may not be what you would expect. You might, for instance, go to our catalog and search for autobiographies. The Library of Congress often uses the term "personal narrative' instead of autobiography.
Library of Congress Subject headings can often be found on the page of a book that provides the publisher's information. The subject heading can then be used to search for a book or article when copied exactly as printed. Another way to figure out what the key words or subject descriptors are for your subject would be to enter the title of a book on the subject that is in our library. Then look at the bottom of the record and find the subject descriptors.
In the library catalog and many electronic databases, an items's subject(s) will be hyperlinked, so that you can click on the subject heading to find similar items. You also might want to note the exact words for future use.
This is an example of a book in the library catalog with numerous subject headings:

Keeping Track of Your Searches
As you begin your research project take a moment and think about how to keep careful records of where you have searched (what catalog or database) and with what keywords. The system needs to be flexible and dynamic since your project may change focus and you need to adapt. What you want to avoid is repeating work (since you may not remember doing a search 1 month later) or leaving a hole in your research (e.g., by searching a database or site early on with one idea and then never returning after you have changed directions). You also need good recordkeeping from the start in order to keep track of your citations!
Expanding or
Narrowing Your Search
Words such as AND, OR, and NOT are used to combine search terms
to broaden or narrow a search in an electronic database. AND will
narrow your search; for example, the search "cats AND dogs" returns
items that contain both the terms cats and dogs (both terms must
appear in the record). OR will broaden your search; for example,
the search "cats OR dogs" will return items that contain either
the term cat or the term dog - both not necessarily both. NOT will
exclude specific items, thereby narrowing your search slightly.
For example, the search "Jasper Fforde NOT book review" will exclude
any book reviews written by or about Jasper Fforde, but will include
any other books or articles written by or about him.
