BRADFORD METHOD Meaning and
Definition
-
The Bradford method is a technique used in bibliometrics and library science to determine the value and relevance of scientific and scholarly articles. It was developed by Samuel Clayton Bradford in 1948. This method is employed to organize and evaluate scientific journals based on their citations and impact in a particular field.
The Bradford method follows the principle that in any given field of study, only a few journals hold significant value and are frequently cited, while the majority have relatively low citation rates. The method provides a framework for identifying the core journals and categorizing them into three zones called Bradford zones. These zones are based on Bradford's Law, which states that journal articles in a given field are distributed across a few core journals and a larger number of less influential ones.
The first zone consists of a small number of core journals that are responsible for the majority of citations in the field. The second zone comprises journals that receive a moderate number of citations, and the third zone includes a large number of journals with relatively low citation rates.
The Bradford method is valuable for information professionals and researchers to identify the most influential journals within a specific discipline, allowing them to focus their research efforts and allocate resources effectively. Additionally, this method aids in the collection development process for libraries, as it helps in determining the important journals to be included in their collections.

Etymology of BRADFORD METHOD
The term "Bradford method" refers to a specific method used for protein quantification in biochemistry. The etymology of the term can be understood by exploring the history and development of this method:
The Bradford method was first introduced in 1976 by Dr. Marion M. Bradford, who was a researcher at the Department of Clinical Chemistry at the University of Georgia. In his publication titled "A rapid and sensitive method for the quantitation of microgram quantities of protein utilizing the principle of protein-dye binding", Dr. Bradford outlined this novel protein quantification method.
The name "Bradford method" arose from the fact that Dr. Bradford was the one who developed and introduced this technique. As researchers and scientists began to recognize the effectiveness and wide applicability of this method, it became popularly known as the "Bradford method" to honor its creator.
