This is SEPM's oldest book series. The first book SP # 1, Bibliography of Otoliths, was published in 1929 and we are now approaching our 100th book in this series. The topic of a book in this series is usually very focused and most often has a team of volume editors and many invited authors contribute chapters on the topic. The more recent publications in this series are the results of oral and poster presentations from Research Conferences or Symposia or technical sessions on the specific topic. All of the chapters in a Special Publication are peer reviewed at the same level as SEPM journals and the quality of the science is matched by the production quality with professional copy editing and typesetting being required. Traditionally the "red books" are printed on high quality paper and hard bound but other media options are always being considered.
