Intersearch is the name given to our line of library management software: we have integrated our own specialist applications with the best of open-source offerings in the information management software space.


Our inter-library loans system, Interloans, is used by hundreds of libraries in the region including the GratisNet and ALIES networks.

Our flagship open-source services are the Koha Library Management System, choice of thousands of libraries around the world, and the DSpace repository for digital library holdings. These are teamed with Prosentient's own popular document delivery systems: Interloans and Interdocs.

 These applications are available as single products that can be configured and hosted for a low monthly fee or as a comprehensive package integrating with existing systems and workflow as required.

Common examples of integration include:

  • using Koha to index e-resources stored in DSpace to provide a unified catalogue of library holdings
  • integrating Koha with Interloans, allowing small libraries to band together and offer inter-library loans
  • integrating Interloans with Interdocs to facilitate document delivery

Case Studies

Koha, Interdocs and GratisNet in Northern Territory Health

The Northern Territory’s Health Library Network signed up for Prosentient System’s document delivery system and were impressed with the after sales service.  “We found Edmund to be very good to work with” explained Resources Management Librarian, Ruby Lindberg.  “No matter how many times we rang he was always patient and helpful.  After sales service and support is very important to us because we don’t have the technical in-house knowledge of the applications to do it ourselves”.  Their good experience with Interdocs soon led the library to join GratisNet, and then to take up the hosted Koha Library Management System.

DSpace: Australian Open Access Support Group

In this case study published by the Australian Open Access Support Group, Gemma Siemensma, Library Manager at Ballarat Health Services, describes the thinking and processes behind the introduction of their DSpace repository

Koha and DSpace in the NSW Parliamentary Library

When the Parliamentary Library of New South Wales began using Koha as its Library Management system and DSpace as its digital repository, the staff didn't do so to make a political statement about the viability of open source software. “This was just the software that fulfilled our requirements,” said Deborah Brown, Parliament’s chief librarian.

While having a physical collection, NSW Parliament library's lifeblood is digitized news media. Through their parliamentary copyright exemption they reproduce and store dozens of articles each day for the use of the Members of Parliament (and their staff) who make up their user base.
