Bradford in 1934 that estimates the exponentially diminishing returns of searching for references in science journals. One formulation is that if journals in a field are sorted by number of articles into three groups, each with about one-third of all articles, then the number of journals in each group will be proportional to 1:n:n². There are a number of related formulations of the principle. The Bradford Factor is calculated as follows: S² × D where: S is the total number of spells (instances) of absence of an individual over a set periodD is the total number of days of absence of that individual over the same set period The 'set period' is typically set as a rolling 52-week period.
