»PIRS« (Personal Information Retrieval System)
P. L. Reichertz · Methods of Information in Medicine · 1968
»PIRS« is a personal information retrieval system for individual reference files. It has been designed to store and retrieve references by identification number, keywords and any string of characters in the name, title or bibliography section of the reference. The keywords have to be defined by the user and hence may be chosen according to his particular needs. The selected references may be printed with or without full text keywords. »PIRS« is available in FORTRAN II-D for an IBM 1620 and in FORTRAN IV-360 for 360 models.
