SCENARIO
Integrated Library Board [ILB]

The Integrated Library Board (ILB) was established on early 90s, to spearhead the transformation of library services in Singapore in the Information Age. Its mission is to expand the learning capacity of the nation so as to enhance national competitiveness and to promote a gracious society. By developing a relevant and responsive library system, which caters to the needs of its people, the ILB will help in creating enlightened individuals who can compete confidently in all sectors.

ILB is creating a network of borderless libraries linking all publicly funded libraries in Singapore to overseas libraries and information services through computer networking. By bringing libraries closer to the public, the ILB places the wealth of knowledge and information within easy reach of all Singaporeans. The vast and continually growing collection of books and multimedia materials allows the library to be one of the most extensive warehouses of information. Through its links with local and overseas information databases, the ILB provides users with global access to information anywhere in the world. The ILB is continually developing and offering new and improved services to its diverse users, and expects to realize its goal of becoming a highly respected information hub in the 21st century.

In order to serve better, ILB segmented and divided into Regional Library, community Library, children library. Addition to the services they also have managed vendors who are suppliers and as well publishers who help them to replenish book and stationary orders (ILB have subsidiary called ILB stationary which sells stationeries.). ILB also caters members and non-members with sophisticated user interface. ILB supports different language section. ILB also has mutual understanding with overseas leading libraries in the world to share resources, complement strengths and develop new programmes and services for mutual benefit.
