• Annotated Bibliography
  • This database is a digital version of Medina's (1996) compilation of the SRER history and all known publications made between 1903 and 1988 about work completed on the SRER and by SRER researchers. The bibliography can be accessed at http://ag.arizona.edu/SRER/history.
  • The bibliography includes over 450 citations with short annotations about their content. The citations are given in alphabetical order. Four appendices list soils, vertebrates, and plant species known from the SRER, and annotated historical maps.

• Update Log
  • This update log records the date and information regarding revisions made to the database.
