The data above were extracted from the Essential Science Indicators database of Thomson Reuters. This database, currently covering the period January 1999 to December 2009, surveys only journal articles (original research reports and review articles) indexed by Thomson Reuters. Articles are assigned to a category based on the journals in which they were published and the Thomson Reuters journal-to-category field-definition scheme. Both articles tabulated and citation counts to those articles are for the period indicated. Naturally, institutions publishing large numbers of papers have a greater likelihood of collecting more citations than those publishing fewer papers.

This ranking is by citations per paper (impact), among those institutions that have collected 25,000 or more citations in plant and animal sciences during the period. For papers with multiple institutional addresses, each institution receives full, not fractional, citation credit. Essential Science Indicators lists institutions ranked in the top 1 per cent for a field over a given period, based on total citations. For the current version, 887 institutions are listed in the field of plant and animal sciences, meaning that a total of 88,700 institutions were surveyed to obtain these results. Of the 887, 40 institutions collected 25,000 or more citations. The ranking by citations per paper (impact) seeks to reveal heavy-hitters based on per paper influence, not mere output. US institutions account for 11 of the 20, followed by two each for the UK and France, and one each for Japan, Germany, the Netherlands, Australia and Canada.

Recent controversy over the future directions of both Stanford and Melbourne university presses have raised questions about the role of in-house publishing arms in a world of commercialisation, impact agendas, alternative facts – and ever-diminishing monograph sales. Anna McKie reports
