Using the acronym CRAAP, we can carefully evaluate the effectiveness, authority, and credibility of a source. CRAAP stands for currency, relevance, authority, accuracy, and purpose.

Figure 1. Taking into account every aspect of the CRAAP acronym will help you to choose the most reliable and applicable sources which will increase your credibility as a writer.

Let’s take a closer look at each of these pieces below.

Currency: The timeliness of the information

Determining when information was published or produced is key to evaluating its relevance. The publication date helps assess its currency—how recent it is or how closely it aligns with your topic’s time period.

There are two aspects to consider:

1. Is this the most recent version?
2. Is this the original research, description, or account?

The importance of these factors depends on your research.

Key indicators of a source’s currency include:

• date of copyright
• date of publication
• date of revision or edition
• dates of sources cited
• date of patent or trademark

Relevance: The importance of the information for your needs

• Information sources with broad, shallow coverage mean that you need to find other sources of information to obtain adequate details about your topic.
• Information sources with a very narrow focus or a distinct bias mean that you need to find additional sources to obtain information on other aspects of your topic.

Some questions to consider are:

• Does the information relate to my topic or answer my question?
• Who is the intended audience?
• Is the information at an appropriate level (i.e. not too simple or advanced) for my needs?
• Did I look at a variety of sources before deciding to use this one?
• Would I be comfortable using this source for my college research paper?

Authority: The source of the information

• a formal academic degree in a subject area
• professional or work-related experience–businessmen, government agency personnel, sports figures, etc. have expertise in their area of work
• active involvement in a subject or organization by serious amateurs who spend substantial amounts of personal time researching and studying that subject area.
• organizations, agencies, institutions, and corporations with active involvement or work in a particular subject area.

Accuracy: The reliability, truthfulness, and correctness of the information

• Are the sources appropriately cited in the text and listed in the references?
• Are quotations cited correctly and in context? Out of context quotations can be misleading and sometimes completely erroneous.
• Are there exaggerations, omissions, or errors? These are difficult to identify if you use only one source of information. Always use several different sources of information on your topic. Analyzing what different sources say about a topic is one way to understand that topic.

In addition to errors of fact and integrity, you need to watch for errors of logic. Errors of logic occur primarily in the presentation of conclusions, opinions, interpretations, editorials, ideas, etc. Some indications that the information is accurate are:

• the same information can be found in other reliable sources
• the experiment can be replicated and returns the same results
• the documentation provided in support of the information is substantive
• the sources used for documentation are known to be generally reliable
• the author of the information is known to have expertise in that subject
• the presentation is free from logical fallacies or errors
• quotations are “in context”-the meaning of the original work is kept in the work which quotes the original
• quotations are correctly cited
• acronyms are clearly defined at the beginning

Some indications that information may not be accurate are:

• facts cannot be verified or are contradicted in other sources
• sources used are known to be unreliable or highly biased
• bibliography of sources used is inadequate or nonexistent
• quotations are taken out of context and given a different meaning
• acronyms are not defined and the intended audience is a general one
• presence of one or more logical fallacies
• authority cited is another part of the same organization

Purpose: The reason the information exists

Identifying a source’s intended audience helps determine its relevance, reliability, and level of detail. The audience influences the style, technical complexity, and depth of coverage.

Also, consider the author’s objectivity—are they trying to persuade? Do they present bias? While it is unlikely that anything humans do is ever absolutely objective, it is important to establish that the information you intend to use is reasonably objective, or if it is not, to establish exactly what the point of view or bias is. There are times when information expressing a particular point of view or bias is useful, but you must use it consciously. You must know what the point of view is and why that point of view is important to your project.

Determining the intended audience of a particular piece of information will help you decide whether or not the information will be too basic, too technical, too general, or just right for your needs. The intended audience can also indicate the potential reliability of the item because some audiences require more documentation than others.

Some indications of the intended audience are:

• highly technical language, complex analysis, and very sophisticated/technical tools can indicate a technical, professional, or scholarly audience
• how-to information or current practices in “X” are frequently written by experts for practitioners in that field
• substantive and serious presentations of a topic with not too much technical language are generally written for the educated lay audience
• popular language, fairly simple presentations of a topic, little or no analysis, and inexpensive tools can indicate a general or popular audience
• bibliographies, especially long bibliographies, are generally compiled by and for those doing research on that topic
