PALNI Shared Systems

The PALNI shared system uses the Aleph integrated library automation software from Ex Libris to implement an online public-access catalog, local cataloging, authority control, circulation control, acquisitions, and serials control for participating libraries. By sharing a central system and union catalog, PALNI libraries are able to reduce overall system administration and maintenance costs. At the same time, Systems Librarians in each library have the flexibility to configure and customize the shared Aleph system to meet unique local library requirements.


The Aleph software runs on a Sun MicroSystems SunFire 6800 server with 10 processors, 24 GigaBytes of Main Memory, and 1.5 Terrabytes of online RAID disk storage. The shared server has been configured into two independent "domains", one functioning as the PALNI shared production sytem, and the second acting as a smaller test server. The production system is licensed to support up to 500 concurrent online users.

During the Summer, 2005, PALNI upgraded its Aleph implementation to the latest Version 17-2 release of the software. Each library is able to customize and maintain the shared system and Online Public Access Catalog to meet its own local campus needs. New Aleph software releases and system enhancements are installed as they become available from Ex Libris.

The PALNI online union catalog now includes 1.9 million unique bibligraphic records and 3.4 million item records representing the combined collections of twenty-two of the twenty-four PALNI libraries. The remaining two PALNI libraries maintain their own, independent stand-alone library automation systems, but participate in reciprocal borrowing and other resource-sharing arrangements with all PALNI libraries.

In addition to Aleph, the PALNI system offers students, faculty, and staff at PALNI institutions access to online reference services and databases through the MetaLib/SFX web-based library "portal". MetaLib includes standard OpenURL resolver capabilities, and can be customized by each PALNI library to provide access to its own local collection of electronic databases.

PALNI libraries also share a ContentDM digital library server to digitize, catalog, and provide web access to unique collections of images and other digitized content held by each library. PALNI's combined digital library collections include more than 30,000 digitized objects, are projected to grow to more than 100,000 objects over the next 12 months. PALNI is listed as an official "data provider" with the Open Archives Initiative.

The PALNI shared systems and project offices are located at the Indiana Cooperative Library Services Authority (INCOLSA) in Indianapolis, Indiana. The computer room at INCOLSA is fully secured and climate controlled, and supports reliable, round-the-clock, system operation. PALNI libraries are connected to the central system using the Indiana Higher Education Telecommunications System (IHETS) state-wide TCP/IP network and the Internet.
