Bradford's Law

Bradford's Law describes how information and knowledge is distributed across different sources, such as books or journals. It suggests that a small number of publications contain most of the valuable information on a subject, while many others have less relevant content. Specifically, it illustrates that if you divide all relevant sources into "zones," the first zone has a few key sources that provide the majority of useful information, while subsequent zones contain many more sources with decreasing relevance. This concept helps researchers understand where to focus their efforts when searching for valuable knowledge.
