These major tax publishers organize primary and secondary authorities into topical or subject formats. We invite researchers to improve their skills by using step-by-step instructions outlined in this research guide.
Find tax primary source citations to and/or full-text of the IRC, legislative histories, regulations, cases, and Internal Revenue Service (IRS) pronouncements such as:

Other features are topical indexes, IRC tables, and finding lists. Consult the "how to use" section in volume 1 for information on publication scope, organization, and indexing.
Use finding aids called citators for judicial history of a court case and subsequent primary/secondary references. (CCH and Thomson/RIA provide citators as part of their tax services.)
Publishers keep services current by sending weekly, biweekly, or monthly updates and supplements to subscribers. Updates are interfiled and outdated pages removed without jeopardizing the overall organization of the publication.
