Data entry has been going on for more than thirty years. Initially the system ran in batch mode on an IBM mainframe. Later, from 1979, it
usable in a time-sharing mode from terminals on the Bar-Ilan campus, as well
as from a growing number of terminals off-campus. At that time this was no small technological feat.
following the development of the CD-ROM, the immense database was
compressed into a single compact disk, and presently the system can be installed on almost any personal computer.
Version 1.0 of the new system was
completed in late 1992, and new versions have been issued more-or-less annually,
with the latest version, 23+, issued in January 2015. Each version includes new texts
the Responsa databases and improvements in the retrieval software.
In 2007, the Responsa Project was awarded the
prestigious Israel Prize for Torah Literature.
