Over the years publishing models changed dramatically and the rise of open access journals has changed the way in which scholars use and share their articles. Changing publishing models, including the rise of open access journals, have reshaped the ways in which scholars share and use journal articles. It has also brought predatory journals into the research arena and therefore it is important to understand and know the criteria for assessing journal quality to ensure that research is published in a quality journal.
Traditional measures, such as peer review, impact factors, and the reputation of the journal will always be important measures to use when assessing a journal. New techniques of assessment have emerged and must be used in conjunction with the traditional measures. These include journal ranking and article-level assessment s (altmetrics) which tracks the relevance of scholarship through non-traditional sources such as blogs, social media, and other online systems.
