E-prints are scholarly and professional works electronically produced and shared by researchers with the intent of communicating research findings to colleagues. They may include preprints, reprints, technical reports, conference publications or other means of electronic communication. Preprints, those selectively shared pre-published documents or articles going through the publication process, have long been recognized and utilized by peer groups throughout the scientific community. Recent technological advances, however, have incorporated preprints with other forms of peer communications to establish an information genre in its own right. Therefore, the more inclusive term e-prints is more appropriate to use currently in describing this rich and valuable source of scientific and technical information that now reaches beyond the scope of pre-published information.
