This series is essentially the same as the Short Course Notes series, except that the contents are specifically focused on using cores. Thus the publications contain extensive core photos. This book series was the result of SEPM Core Workshop instructors, who wanted to officially publish their workshop contents, often when they felt that they would be teaching the workshop multiple times and did not want recreate the handouts each time. The first book in this series was published in 1980 and the most recent one was in 2008. Many instructors use one time handouts and exercise materials, often relying on "fair use" to avoid copyright violations of some of the non-original material they use in their course. However, to officially publish in the Core Workshop Notes Series, authors must follow the same copyright guidelines as all of the series. This means that any content that is from another copyrighted source will need a release. Likewise, releases from companies may be needed to publish core photos. Because of the time frames involved when workshops are planned, this series is not peer reviewed, professionally copy edited or typeset beyond desk top publishing standards. Usually SEPM receives a "finished" product, which is reviewed by SEPM staff for any obvious errors. Core Workshop Notes have been published in both print (usually soft bound) and digital formats and in more limited numbers than SPs or CSPs. Notes Series' authors do not have to actually teach the workshop prior to publication.
