Bradford's law is a pattern first described by Samuel C. Bradford in 1934 that estimates the exponentially diminishing returns of extending a library search.

Here is how it works. Suppose that a researcher has 5 core scientific journals for their subject. Suppose that in a month there are 12 articles of interest in those journals. Suppose further that in order to find another dozen articles of interest, you have to go to 10 journals. Then that researcher's Bradford multiplier bm is 2 (ie 10/5). For each new dozen articles, that researcher will need to look in bm times as many journals. After looking in 5, 10, 20, 40, ... journals, most researchers quickly realize that there is little point in looking farther.
