The storage, description, collection, organization, and selection of legal information is central to a legal system, whether public or private, professional or lay person, structured or unstructured, textual or non-textual. The ability to get timely information where it is needed is as important to law as it is to any other field, given that law is a system of written rules and procedures. Ignorantia juris non excusat – ignorance of the law is no excuse. But where citizens seek to know the law and cannot find it, they have a right to question its legitimacy, at least as applied to them. The function of the reference librarian within a brick and mortar library, while still invaluable, does not scale to the magnitude of the problem. Technological information intermediation, such as a search engine, can thus be increasingly viewed as a necessary component of a modern legal system, and familiarity with the basic concepts is an important tool in the legal technologist’s toolkit.
