The Wikibook is organized into Books in four sections, Chapters in books, and Topics in chapters.
The four sections are (1) General & Special topics pathology, (2) Clinical pathology / Laboratory medicine, (3) Histopathology / Anatomical pathology, and (4) Other Wikibooks.

Any user can create and edit a topic but must first log in to proceed. Once a topic is considered complete it can be locked by the Administrator for further editing. Individual wikibooks and chapters can only be created and edited by Administrators at pathpedia.com. Users can suggest creating / editing Wikibooks and chapters by emailing to the Administrator at admin@pathpedia.com. This allows for managed editing of wikibooks.
