The Project Management Institute sells its "Project Management Body of Knowledge" online. Known as the "PMBOK Guide," it is also available from retailers such as Amazon.com, Barnes & Noble and Wal-Mart.
The Project Management Institute offers the "PMBOK Guide" on its website's marketplace. The group's members receive bonus materials with purchases, such as the "Project Management Process Groups Interaction and Processes" poster available with the guide's fifth edition, as of 2015.
The organization releases new editions every few years, compiling changes in best practice for the project management profession and additions based on methodologies from relevant knowledge areas. The group also releases interim errata sheets for changes made between versions. Because the guide is the basis for the Project Management Institute's Project Management Professional certification, it is important to purchase the currently supported version.
Amazon.com offers the "Project Management Body of Knowledge," along with books based on the guide, including study guides, overviews, lab manuals and industry-specific extensions. The book consistently ranks in the number one best-seller category for professional test materials. Amazon offers a rental option for the book and gift cards for used copies.
Barnes & Noble offers new, used and rental options for the guide. In-store pick-up is available upon ordering.
Walmart.com sells the book in paperback and offers free in-store pick-up at certain locations.
