MMPA 6116 Week 3 Discussion: Home


For your Week 3 Discussion, you have been asked to find a peer-reviewed article from an international journal, and to consider the advantages and disadvantages of peer review. This guide will help you locate the resources you need to complete your post. 

After reviewing this guide, you will be able to:

  • use peer-review limiters in the Library databases
  • access and link to peer-reviewed articles from an international journal 
  • explain the importance of peer review 

The importance of peer review

While peer review is an important part of scholarly research and publishing, there are other non-peer-reviewed sources of information that may be useful in certain situations. 

Sources that are not peer reviewed may include:

  • popular press resources, such as magazines and newspapers
  • dissertations 
  • government information and websites, such as the CDC website or Census Bureau data
  • industry or trade publications aimed at practitioners in a field, such as Harvard Business Review or NEA Today

Want more information about peer review, and how you can determine if an article is peer reviewed or not? Learn more with our Peer Review guide.

Would you like more information about evaluating resources? Find evaluation criteria and tips for the scholarly researcher on our Evaluating Resources guide.     

What if you find an article mentioned elsewhere or from outside the Walden Library? Find out how you can verify if a journal is peer reviewed or not with information from our Verifying Peer Review guide

Find peer-reviewed journal articles in international journals

Persistent or permanent links

A persistent link is a permanent URL to a specific journal or article within a database like ProQuest or EBSCO. Database vendors may have their own persistent link system or they may use the DOI link system and OpenURL.

A persistent link allows you to access a specific journal or article without having to search for it again. Persistent links for Walden Library databases will require your Walden user name and password. 

Some other names you might see are: 

  • permalink
  • PURL (permanent url)
  • stable link 


Do not assume that the URL in the browser address bar is a permanent link. That URL may:

  • change in the future
  • include session information causing the URL to only be valid for a single user session
  •  be a temporary Find@Walden full-text service URL that is not stable.


Every database is different in how they provide persistent links, and some do not. Below are examples from two of our main databases. If you have questions about other databases, please contact the Library. 

Example of a permalink in EBSCO databases

In EBSCO databases follow these steps.

  1. Click on the title of the article you want.
  2. On the Detailed Record (abstract page), select Permalink from the options on the right. The persistent link (permalink) will appear at the top of the article title. 

  3. Copy the link displayed in the Permalink box. 

Example of a persistent link in ProQuest

Follow these steps to find the persistent link in ProQuest databases

  1. Click on the title of the article you want. 
  2. Select the Abstract/Details tab. 

  3. Copy the Document URL near the bottom of the record.

Think about it

1. How easy was it to locate peer-reviewed articles in the database search you tried? 

2. Try the same search, but uncheck the peer review limiter box. Looking through these results, how easy is it to determine if an article is peer reviewed or not? What differences do you notice in the search results?

3. Can you think of a situation where it might be better to use resources that are not peer reviewed?
