Marc authored The Florida Civil Litigation Handbook: Actions, Defenses and Evidence and Rules, which was published annually by Matthew Bender & Co., Inc. from 1997 through 2000. He now publishes the original content of the Handbook, for which he owns the copyright, through his own publishing company, in an annual series entitled The Florida Litigation Guide (www.flalitguide.com). The Guide contains a listing of the elements of popular common law causes of action, citations for the most recent state and federal court cases listing the elements of the actions and various defenses to the actions. Lawyers from virtually every major Florida law firm, as well as countless practitioners from medium and small firms, solo practitioners and government attorneys, as well as members of the judiciary, routinely rely on Marc’s publication in Florida litigation matters.
