How to Evaluate Secondary Sources
You can use the ACT UP method when assessing and analyzing secondary sources. Consider the following when you're evaluating those sources:
- AuthorityIs the author(s) of the work listed? Can you determine their expertise? With what organization are they associated? What are their credentials?
- CurrencyIs this up to date or outdated information? Can you tell when the information was created/revised/published? Are dates given for when it was created and last updated? If it's a website, is it up-to-date with working links?
- TruthCan the information be verified? Are the arguments backed up by clearly cited evidence and statistics?
- UnbiasedDoes the language, tone, or treatment of its subject give the information a particular slant or bias? Is the work objective? Is it designed to sway opinion? Does its organizational affiliation indicate bias?
- PrivilegeWho is missing from the research? Do authors of different backgrounds (ethnic, gender, socioeconomic, etc.) agree with or push back on this work?
Evaluating Books
Title
Words used in the title can often give you clues about a book's intended audience or purpose. Scholarly books usually have titles that sound more formal. For example, books with titles like Complexity and Evolution: Toward a New Synthesis for Economics have a much greater likelihood of being scholarly as compared to books with titles like Business Cat: Money, Power, Treats.
Publication Date
Timeliness and currency are important when selecting a book for your research. Whether or not a book is considered current will vary greatly depending on the discipline and the particular topic. Additionally, since it can take years to write and publish a book, if you're looking for the most up-to-date information available, you may need to consult other types of sources that have a faster publication cycle.
Citations
Authors of scholarly books cite their sources using formal citation styles like Chicago, MLA, APA, or others. These references may appear as parenthetical citations, footnotes, endnotes, or bibliographies. When evaluating the quality of a scholarly book, it's often useful to examine these citations to get a better sense of the relationship between the book and other scholarly work on the topic.
Tone and Language
The text of scholarly books will usually have a more serious tone and use formal or technical language that may not be easily understood by a general audience.
Author/Editor
Scholarly books are almost always written by professors or researchers affiliated with universities or research institutes. Some scholarly books, often called edited books or edited volumes, are co-authored by a group of people who are each responsible for a particular chapter. The editors of edited volumes are also professors or researchers.
Most scholarly books list their authors' and/or editors' credentials (i.e., affiliations with universities or research institutes, previous publications, and sometimes academic degrees). This information can be useful in determining whether someone is considered an authority on the topic they're writing about.
Publisher
There are several different categories of publishers, each specializing in particular types of book. Understanding who published the book will help inform your analysis of the book's content.
Evaluating Journals
Professors often suggest that students include articles from scholarly, refereed, or peer-reviewed journals as resources for their research papers. These articles are authored by experts in their fields and reviewed by peers before getting accepted for publication. See the information below to help you distinguish between the three main types of periodicals.
You can also look up a journal or any periodical in UlrichsWeb to determine whether it is peer reviewed, also called "refereed".
Scholarly Journal
e.g. Journal of American Studies
Appearance: Sober design, little advertising, mostly text with some graphs and tables.
Audience: Students, researchers, scholars, specialists in a particular subject.
Content: Scholarly journals contain original research, theoretical issues, and new developments in the subject discipline.
Articles:
- Present the results of original research performed by the authors; often include a review of existing literature on the topic.
- Include specialized vocabulary of a subject discipline.
- Written by subject specialists identified by name, with degrees and academic affiliation usually given.
- Generally medium-length to long (5-20 pages or more).
- Meticulously documented; extensive references and/or footnotes.
- Most often peer-reviewed by other authorities in the field to validate findings.
Trade Journal
e.g. Steel Times International
Appearance: Visual; some advertising related to the field, photos.
Audience: Members of a particular trade, profession or industry.
Content: Trade and professional journals contain news, trends, technical and practical aspects of the trade, profession or industry.
Articles:
- May present industry news and/or original research.
- Include specialized vocabulary of a trade, profession or industry.
- Written by staff writers and freelancers, usually professionals in the field.

- Evaluated by editorial staff that may include experts in the field, but not peer-reviewed.
Please note that not all articles found in magazines, or journals, will contain the noted characteristics. Use careful judgement in determining if an article in a scholarly journal actually presents in-depth, original research, or if an article in a magazine or trade journal goes beyond presenting news and current trends.

Audience: General readership
