What about reference sources?

reference source

• Any publication from which authoritative

information can be obtained, including but not

limited to reference books, catalog records, printed

indexes and abstracting services, and bibliographic

databases. Individuals and services outside the

library that can be relied upon to provide

authoritative information are considered

resources for referral.

And reference books?

reference book• A book designed to be consulted when authoritative information is

needed, rather than read cover to cover. Reference books often consist

of a series of signed or unsigned “entries” listed alphabetically under

headwords or headings, or in some other arrangement (classified,

numeric, etc.). The category includes almanacs, atlases, bibliographies,

biographical sources, catalogs, concordances, dictionaries, directories,

discographies and filmographies, encyclopedias, glossaries, handbooks,

indexes, manuals, research guides, union lists, yearbooks, etc., whether

published commercially or as government documents. Long reference

works may be issued in multivolume sets, with any indexes in the last

volume. Reference works that require continuous updating may be

published serially, sometimes as loose-leaf services.

Know your reference books

When you pick up a reference book:

• Note the author and publisher, and perhaps the author's

credentials.

• Check the copyright date. Given the type of information the

tool covers, is it likely to be current enough?

• What is the purpose and scope of the book (check for

preface)?

• Review the table of contents. What is the scope of the

material? Is it biased toward one viewpoint?

• Review the index (if there is none, is that a significant

drawback?). What approaches does the index use?

More know your books

• Page through to see what special features may be there. Are there photos? Charts and graphs? Appendices?

• What is the level of the book? Who is the intended audience?

• Make up a short “test” for the book. Think up some questions that you feel, based on the review you've done, that the book should be able to answer. Does it?

• Has anyone else on the staff had experience with this book? How do they feel about it?

Arrangement of

Reference Books

Alphabetical order

There are two methods of alphabetizing. The letter-

by-letter system ignores punctuation and spaces

between words. The word-by-word system organizes

by the first word, then the second word, and so on.

Here is an example:

• Letter-by-letter Word-by-word

Bookcase Book club

Book club Book fair

Bookend Bookcase

Book fair Bookend

Critical Evaluation of Resources

How do you make sense of what is out there

and evaluate its authority and appropriateness

for your research?

• Suitability

• Authority

• Other indicators

• Reference Sources

Suitability

Scope

• What is the breadth of the article, book, website or

other material?

Audience

• Who is the intended audience for this source?

Timeliness

• When was the source published?

Scholarly vs. Popular • http://guides.lib.berkeley.edu/evaluating-resources#suitability

Authority

Who is the author?

What are his or her credentials?

• Sometimes information about the author is listed

somewhere in the article. Other times, you may

need to consult another resource to get background

information on the author. Sometimes it helps to

search the author’s name in a general web search

engine like Google. • http://guides.lib.berkeley.edu/evaluating-resources#authority

Other indicators

Documentation

• A bibliography, along with footnotes, indicate that the author has consulted other sources and serves to authenticate the information that he or she is presenting.

Objectivity

• What point of view does the author represent?

Primary vs. secondary research

• In determining the appropriateness of a resource, it may be helpful to determine whether it is primary research or secondary research.

What about Tertiary Sources?

You’ll find some

differences in

interpretation about

these examples. As

you see, some would

consider encyclopedias

secondary sources.

See this guide from the

University of Illinois,

for example.
