The Oxford Companion to American Law by American Law Reports (ALR) is an annotated law report that contain articles (called annotations) on narrow topics of the US law. Although similar to encyclopedic entries, ALR annotations differ in that they are not organized alphabetically, but in the order of when the leading case for the particular topic was decided. Each annotation discusses in-depth a very specific legal concept and provides cases from every US jurisdiction that have taken a position on that topic. Along with citations to cases, the annotations also provide references to statutes, digests, texts, treatises, law reviews, and legal encyclopedias on that topic.
Restatements of the Law are a set of highly regarded treatises on general principles of common law. The Restatements is an attempt to codify case law. They are created by the American Law Institute, a prestigious organization comprising judges, professors, and lawyers. Their aim is to distill the "black letter law" from cases, to indicate a trend in common law, and, occasionally, to recommend what a rule of law should be. In essence, they restate existing common law into a series of principles or rules. Although the Restatements are not a primary source of law, they are considered persuasive authority by many courts, especially the Restatement of Torts and the Restatement of Contracts.
The Law Library has a number of Restatements in print. Search "Restatement of the Law" in the library catalogue to see the full list. However, the most up-to-date Restatements can be accessed online via the Westlaw International and Lexis databases.

A common approach to finding a research topic is to examine an unresolved legal issue. Unresolved legal issues can occur when courts have split in their interpretation of the law, leaving the ultimate meaning of the law unresolved.
In the United States, this is known as a 'circuit split' because it is based on federal circuit courts interpreting the same legal issue differently. These sorts of issues are ripe for appeal to the US Supreme Court, the highest court in the land.
A research topic may describe the split, identify any issues that may be influencing the courts, and propose a way to distinguish the situations or resolve the discrepancy. These topics can be very timely and relevant. However, if the discrepancy is resolved before your paper is completed, the topic can be rendered entirely obsolete. Because these topics are so popular in the United States, there are resources dedicated solely to tracking circuit splits, including the following:
