We compare the distribution of authors of papers published in GEOPHYSICS during 1975-76 to SEG membership distribution in 10 employer classifications. Also, paper distribution is compared to membership distribution in 9 disciplines.A disproportionately large percentage (43.2) of authors are in academic institutions which employ a small percentage (5.6) of Society members. Percentage of authors in government agencies (20.6) and in service companies (5.8) also are larger than percentage of members in these two employer classifications (6.7 and 2.4, respectively). Percentage of authors in petroleum companies (19.2) and in contracting companies (2.3) are considerably less than percentage of members in these two employer classifications (50.8 and 14.6, respectively).Percentage of papers (55.6) in the four potential field disciplines (gravity, magnetic, electrical, and electromagnetic) far exceeds the percentage of SEG members (30.5) in these disciplines. By contrast, percentage of papers on the seismic method (30.6) is appreciably less than percentage of members (56.5) in this discipline.
