Many law departments struggle with knowledge management. Sun Microsystems has put a big dent in the problem using wikis. 

Legal Departments, Law Firms Weighing Wikis (The Recorder, 25 Sep 2008) reports “Between January and the start of September, there had been 1,200 articles published internally [on the wiki] at Sun with over 8,000 edits among them”. It also reports that global sales and services law group built a library of common legal clauses in a specialized wiki, reducing the time the project would otherwise have taken from months to weeks.
