Westlaw would be another great resource for legal research. It provides excellent tools in reference to legal research. Their Shepard’s tool provides more in-depth discussion of the treatment and citation of cases. Furthermore, it outlines those cases which have received negative treatment. The primary difference is that they rank how strong the case has remained over time. Additionally, they provide links to west keys. This again allows ready access to the cases themselves. One major difference is that the schools that I have attended provide access to LexisNexis, but not to Westlaw. This may be due to agreement, licensing cost, or a myriad of other factors. The result is that you become more familiar with LexisNexis and, therefore, tend to prefer the one over the other.
