Document Review and the High Cost of Civil Litigation
-----------------------------------------------------
Despite soaring discovery costs, the legal industry has by many accounts been slow to adapt to  
the 21st century.  Legal discovery refers to the initial phase of litigation during which the  
disputing parties exchange information relevant to the case.  Today, the majority of material  
gathered consists of electronically stored information (ESI).  ESI is an umbrella term used to  
describe all electronic data, including e-mail (Outlook, Entourage, EML / RFC-2822) and e-docs  
(PDF, plain text).  

Traditionally, ESI has been reviewed in what is called a *linear* fashion.  This means teams of
