I have been hearing a lot about a legal research website called Casetext, so I thought I would check it out.
Casetext is a website in Beta that combines legal research and social media. How you ask? The site offers users full text case law along with the ability to add annotations.
The annotations can include related cases, relevant journal articles, and general commentary. For individuals who choose to add related cases, the citing references they contribute can be to the entire case or a particular paragraph.
Researchers can search by keyword, case name, or citation for free. The entire decision, along with any contributed annotations, is available.
If you would like to print the case as a .pdf, copy selected portions of a case with citation information or save cases, the cost appears to be $20 per month.
Coverage includes U.S. Supreme Court decisions and a significant portion of federal cases. Currently, circuit court decisions go back to 1 F.2d, while District court cases go back to 500 F. Supp.
