Every lawyer is familiar with key number legal research using the time honored West manual system.
The problem with manua l legal research systems is that the lawyer doesn't have the time to extract relevant research from every book on the shelf. Thus, the first and primary advantage of CALR is the use of the computational power of the microchip to examine large numbers of l egal resources for relevant search terms. Generally, Boolean logic systems are used to extract information from legal resources. The West search engine allows serious researchers to examine legal res ources using connectors that will locate search terms within one word of each other. As an assumption, then, let us presume that paper libraries are obsolete, and that CALR is the way to go.
