Intro to NY Courts
Great introduction to New York State and City courts, including their jurisdictions, claim amounts handled, etc. To find out where court decisions are published for each court, see the NYU Law Library Guide to NY Court System.
Some decisions (completed cases) can be found in LexisNexis Academic, others in the online NY Court Reporters. If the case isn't covered in either, you may need to go to the Law Library and use either the print Reporters, LexisNexis Pro, or a similar resource.
