Its six top-level subject categories are Agriculture Sciences, Arts & Humanities, Basic Sciences, Biomedical Sciences, Engineering & Technology, and Social & Management Sciences with a three-layer hierarchy to find more specific subjects. The last of these subject categories include Law with materials on Arbitration, Banking Law, Constitution and Judicial System, Corporate laws, Crime, Criminology and Law Enforcement, Domicile and Immigration Laws , Environmental Law & Policy, Foreign Trade & Commercial Transactions, Industrial Relations Law, Insurance Law, Intellectual Property, Investment Laws, Regional and International Law, and Taxation Law.
