also fund student travel grants, leadership training, and field camps. Journals, books, and newsletters SEG's publications program helps the society fulfill its mission of promoting the science of geophysics and the professional development of geoscientists by disseminating information about geophysical research and applications through a variety of channels. The reference publications program publishes a wide range of books, DVDs, CDs, videos, and slide sets in several series. These can be purchased online through the SEG Book Mart. Journals SEG publishes three journals. Geophysics, published by SEG since 1936, is an archival journal encompassing all aspects of research, exploration, and education in applied geophysics. The Leading Edge (TLE) is a gateway publication introducing new geophysical theory, instrumentation, and established practices to scientists in a wide range of geoscience disciplines. Most material is presented in a semitechnical manner that minimizes mathematical theory and emphasizes practical applications. SEG's newest publication, Interpretation, launched in August 2013, is a peer-reviewed journal co-published by SEG and AAPG for advancing the practice of subsurface interpretation. SEG Digital Library The Digital Library is SEG's online resource for the SEG research collection. SEG's online offerings include electronic versions of Geophysics and TLE; the Encyclopedic Dictionary of Applied Geophysics, fourth edition; SEG Technical Program Expanded Abstracts; the multisociety Digital Cumulative Index; SEG Technical Standards; SEG news; the SEG Extra e-mail newsletter; and the SEG Yearbook. The Digital Library also offers research collections from the Environmental and Engineering Geophysical Society (EEGS) and the Australian Society of Exploration Geophysicists (ASEG) societies. Professional Development SEG Professional Development consists of four programs: SEG Distinguished Instructor Short Course Continuing Education short courses Distinguished Lecturer Honorary Lecturer Distinguished Instructor Short Course (DISC) The SEG Distinguished Instructor Short Course (DISC) is SEG's primary professional development program. The DISC is a one-day course taught by a prominent geophysicist on a current topic of interest to a broad audience of geoscientists. The DISC visits over 25 sites around the world each year. Continuing Education The backbone of the SEG Professional Development program is Continuing Education (CE). These short courses, taught by industry experts, cover topics from the fundamental to the leading edge of geophysics. CE courses are held in one of three ways: public courses, section-sponsored courses, and contract (in-house) courses. Public courses are sponsored directly by SEG, a series of courses called an [Education Week] is offered four times per year, once in west Houston, once in New
