Treatises—in print or online—summarize the law, backed up with copious case citations in footnotes. They exist in all major areas of law, including banking, contracts, corporations, and employment law. Other practitioner materials (continuing legal education materials, manuals, deskbooks, etc.) are also useful.
Note that treatise publishers generally only license them to one online service, so you won't find the same treatise on, say, Lexis and Westlaw. Westlaw (owned by Thomson Reuters) has treatises published by Thomson Reuters; Lexis has treatises published by Lexis Publishing; Bloomberg Law has treatises published by the ABA, BNA Bloomberg, and others. Because of this lack of overlap, it is often worthwhile to search in more than one service (as long as your are a student and the library provides you with unlimited access to all three).
ALR annotations provide very brief summaries of cases, from around the country, on focused topics. ALR is available on both Westlaw and Lexis.
Legal encyclopedias summarize black-letter law, with footnotes citing zillions of cases. Am.Jur.2d is on both Westlaw and Lexis, but it is updated more frequently on Westlaw (quarterly versus annually) (because it's published by Thomson Reuters). C.J.S. is available only on Westlaw.
