The impact factor, also known as the journal impact factor, is a numerical value that reflects the average number of citations received by recent articles published in a particular academic journal within a given year. It serves as a valuable tool for assessing the influence and significance of a journal within its respective field. Journals with higher impact factors are generally considered to be more prestigious and influential than those with lower values.
The concept of the impact factor was pioneered by Eugene Garfield, the esteemed founder of the Institute for Scientific Information. Through his groundbreaking work, Garfield established the importance of quantifying the impact of scholarly publications, thereby revolutionizing the way in which academic journals are evaluated and ranked. Today, the impact factor continues to play a crucial role in aiding researchers, publishers, and academic institutions in their quest to identify and recognize high-quality scholarly work.
