title: The EM Program Package: A Platform for Image Processing in Biological Electron Microscopy
abstract: EM is a software package developed for image processing in the field of biological electron microscopy. After a brief summary of its history, an outline of the package is given, by describing some characteristic features rather than by a complete report of all facilities. New developments, connected with the introduction of a UNIX version and the advent of automated electron microscopy, are described in more detail.
