The Heart of the System

Designed and developed in partnership with some of the largest libraries in the United States and beyond, CARLSolution uses established, thoughtfully created design and development principles. It showcases libraries’ individual strengths, while freeing staff from routine functions. This UNIX and SQL/Oracle-based solution uses Web and MS Windows client software, CARLConnect and CARLX, to offer an array of services and features.

CARLSolution serves the needs of the largest libraries, but is scalable to handle the demands of consortia of any size, while preserving each library’s autonomy. These benefits are available whether you choose a cloud hosted solution, or prefer to maintain equipment on-site.

Open System Integration

CARLSolution is a true open system. In fact, TLC collaborates with countless other leading technologies and library partners to create the ideal user experience. The robust database structure and CARLSolution web service APIs offer a proven foundation to help your library deliver an unparalleled and ground-breaking experience to your community.

Leading-Edge, Flexible Modules

CARLSolution provides public libraries with a significant suite of unique, dynamic and configurable features including:

  • Real-time processing of activities logged
  • Automated bibliographic and item level suppression
  • Global update options with the staff client
  • Highly configurable library workflow and patron services such as claims returned, floating collections, outreach, and sophisticated email, phone and text notice features

  • Availability of demonstrated web API’s that expand options to integrate, extend, analyze, modify, and open data to meet the needs of today’s modern library

Beautiful and Powerful OPAC Software

CARLConnect Discovery constitutes the core of CARLSolution’s configurable, multilingual OPAC environment. CARLConnect Discovery uses a Lucene search engine to offer powerful search capabilities with easily accessed interfaces for diverse communities, and it can present any language, including those with non-Roman characters. It also provides outstanding integration and presentation of multimedia/multiformat metadata, including e-book, photo, audio, and video collections. Our open access to CARLSolution’s APIs and modular approach to OPAC functionality maximize your ability to customize your interface and build a portal that blends with your Web site.

Patrons may pay fines and fees using a credit card, create personal profiles, save favorite searches, register for RSS feeds, and receive program event alerts via e-mail. Patrons may create personal lists to save titles to their “bookshelf” to place holds or keep items in a Netflix-like queue.
