ITIL has recently undergone a refresh, and this page presents information about the newly published version 3 (ITIL v3), the core books for which were published on 30 June 2007. The major difference between v3 and its predecessor v2, is that v3 has adopted an integrated service lifecycle approach to IT Service Management, as opposed to organising itself around the concepts of IT Service Delivery and Support.

The Information Technology Infrastructure Library (ITIL) is a customizable framework of best practices designed to promote quality computing services in the information technology (IT) sector. As an IT Service Management (ITSM) framework, ITIL provides a systematic approach to the provisioning and management of IT services, from inception through design, implementation, operation and continual improvement.The processes identified and described within ITIL are supplier and platform independent and apply to all aspects of IT infrastructure. Since the mid 1990s, ITIL has been generally considered a de facto international standard for IT Service Management.
