The good folks at the Federal Judicial Center have a number of resources available that may be of use or interest to securities litigators. Two in particular are worth highlighting.
The first is a monograph, Federal Securities Law, authored by Prof. Thomas Lee Hazen. The text is meant as an introduction to the intricacies of the federal securities laws for federal judges.
Though it is a bit dated, having been published in 2003, it is nonetheless a good starting point for one looking for a broad overview of the federal securities laws - and the price (free!) is certainly right.
Prof. Hazen is the Cary C. Boshamer Distinguished Professor of Law at the University of North Carolina at Chapel Hill School of Law.
The second securities class action related resource from the FJC is the fourth edition of the Manual for Complex Litigation. The nearly 800 page tome is aimed at assisting federal trial judges in managing class and complex litigation. For those not wishing to download the entire manual, the table of contents here allows users to download smaller pieces. Though judicial officers are the intended audience, it is nonetheless a helpful resource used often by practitioners. Note that this is not the annotated version available from Thomson - West.
