Doesn't seem to be obvious, does it? Imagine asking that question about a C
program. - Note that I am not saying that PSI is ideal for the Prolog 1000
database, especially because it might exclude users of other platforms.
(PSI can export in many formats, though, including Prolog-readable text.)

Still, using the publicity, from the ReadMe file of PSI (pronounced "psee"):

PSI is a handy system for the management and retrieval of your
personal data, be it addresses, CD collections, or bibliographic
references. It is intended for the non-commercial user. It may not
be as full-fledged as some data-base systems, but has some features
that you won't find in most commercial systems. Also, you may find
it easier to set up and faster to use. (Try the sample sessions!)
PSI is useful for a broad range of data. Indexing with descriptors
makes searching for the data you need fast, and the interface to
other data-base formats (import and export) is quite powerful.

PSI has been written in LPA MacProlog and is a "genuine 'double clickable'
Mac application". PSI runs on all Macs with System 6 or 7 in 1MB of main
memory. As LPA MacProlog isn't yet 32-bit clean, PSI isn't either. Exten-
sive documentation and some examples are included.

PSI is available by anonymous ftp from sumex-aim.stanford.edu, directory
info-mac/app, file psi-23.hqx. It was also available on a recent Nautilus
CD-ROM (if you happened to get it) and will be on the first Info-Mac CD-
ROM.
