Almost a decade ago I had the pleasure of meeting and first working with Olivier Serrat from the Asian Development Bank. We worked together on a range of initiatives for ADB including developing a series of courses on learning in organisations. During that time Olivier wrote nearly 100 short and readable papers on issues related to organisational learning, knowledge management and leadership. In 2010 he brought these together in a single volume and it has been a constant and valued companion to me in my work. More recently, Olivier has added to the already comprehensive list of topics he had covered in his original publication and has now published a new collection of 126 of his articles in e-book form. Knowledge Solutions comprises an encyclopaedic resource on learning in organisations and is a significant contribution to the field. In an extremely welcome gesture of generosity his publisher – Springer – has made all of this content available Open Access which means we can download all the chapters free.
