Directory of Open Access Journals. DOAJ is a community-curated online directory that indexes and provides access to high quality, open access, peer-reviewed journals.
Calculated using 3 years of data.
2016 Impact Factor = # of citations to all items published in 2014 & 2015
# of articles & reviews published in 2014 & 2015
Median age of the articles that were cited in the JCR year. Half of a journal’s cited articles were published more recently that the cited half-life.
EIGENFACTOR The Eigenfactor calculation is based on the number of times articles from the journal published in the past five years have been cited in the JCR year, but it also considers which journals have contributed these citations so that highly cited journals will influence the network more than lesser journals. References from one article in a journal to another article from the same journal are removed, so that Eigenfactors are not influenced by journal self-citation.
ARTICLE INFLUENCE The Article Influence determines the average influence of a journal’s articles over the first five years after publication. It is calculated by multiplying the Eigenfactor by 0.01 and dividing by the number of articles in the journal, normalized as a fraction of all articles in all publications. This measure is roughly analogous to the 5 year Journal Impact Factor in that it is a ratio of a journal’s citation influence to the size of the journal’s article contribution over a period of five years. The equation is as follows 0.01 x Eigenfactor Score X Where X = 5 Year Journal Article Count divided by the 5 Year Article Count from All Journals. The mean Article Influence for each article is 1.00. A score greater than 1.00 indicates that each article in the e journal has above-average influence. A score less than 1.00 indicates that each article in the journal has below-average influence.
Far from being duped, researchers with few resources are turning to “predatory” journals to publish articles and polish resumes.g the main
Open-access academic publications were supposed to lower the barriers to knowledge. But when the walls came down, opportunists came in.
" I used to use Google Scholar when I was looking into an area that was new to me. But now that I know that Google Scholar does not vet the journals it lists [emphasis added], I avoid it."
The article discusses why University of Colorado at Denver librarian Jeffrey Beall deleted a list of other 1,000 academic journals he deemed untrustworthy. IT uggests this may have been due to pressure from other university librarians, the college administration, or publishing companies. The article goes on to look at how the incident reflects challenges associated with researchers sharing and collaborating on work.
