- Looseleaf service
A looseleaf service is a type of publication used in
legal research which brings together both primary and secondary source materials on a specific field or topic inlaw . For this reason they are sometimes called "subject-matter services".Looseleaf services are most commonly used for research in areas of law which change rapidly due to regulatory and administrative developments (such as
tax law ,environmental law ,financial regulation , andlabor law ). Looseleaf services are typically contained inring binder s to keep them updated, because they are published fairly frequently (at minimum monthly, sometimes weekly or bi-weekly) in order to keep the information therein current. Most law libraries have a subscription to several of these services, and many of the more popular services are available electronically as well.Types of looseleaf services
