This document provides an introduction and overview of a sourcebook on corporate social responsibility and sustainable business. It discusses how companies are now expected to consider social and environmental impacts and operate sustainably. The sourcebook aims to highlight the current state of knowledge on CSR and the role of leadership through an annotated collection of academic and business literature from 2000 onward. It uses three methods to select relevant sources: a systematic keyword search, a random search, and reviewing reference lists. The sourcebook's purpose is to provide leadership insights from the literature on approaches to CSR, drivers of commitment, corporate identity/ethics, stakeholder partnerships, and organizational challenges.
