The Boston Public Library is counting down the final days to a major computer systems upgrade. The new system from Polaris will replace the 12 year-old implementation of our Horizon Integrated Library System or ILS. The ILS is the system that staff use to run the library, from checking in and checking out books, doing catalog searches, maintaining inventories of items, catalog data, and patron data and helps provide secure access to patrons for other services from wifi to printing and remote access over the web. It is also used for purchasing, acquiring, and processing new books, for filling patron holds and routing books throughout the system. The BPL ILS also services 8 other libraries throughout the Greater Boston Area as part of the Metro Boston Library Network, which also includes several Boston Public School Libraries. For specific information about the migration and its impact, please check here or keep an eye on this blog for upcoming posts with more background information.
