Lexis+ and Westlaw are vast databases that contain millions of documents and offer powerful search features. The library highly recommends obtaining at least some training on each service. Even a short orientation before diving in will save you a tremendous amount of time.
Each service offers training materials (note that you may need to be logged in to a service to access its training tools).
In addition, you can reach out to our Lexis+ and Westlaw representatives, whose contact information can be found on the front page of each service.
