Ranked among the best university libraries in the United States, the Harold B. Lee Library (HBLL) at Brigham Young University houses over 6 million items across 98 miles of shelving. Over 10,000 patrons enter the HBLL each day, from students and professors to alumni and community members. With so many users to serve, the HBLL requires powerful library automation software. BYU relies on SirsiDynix Symphony and BLUECloud to support their collection. Symphony is a powerful, dependable ILS, but in order to get exactly the solution they want, BYU sometimes chooses to make their own applications. That’s where SirsiDynix APIs and web services come in.
