``This book gives a comprehensive introduction to the theory of coherence of analytic sheaves as developed by Oka, Cartan, Grauert and many others. The exposition is aimed at beginning graduate students, is based on lectures given by the author in Tokyo, and follows an unusual order in presenting the material, which should particulary benefit beginners. .............. Overall the book is extremely readable and yet detailed and clear. Its novel viewpoint on Okafs theory, essentially inverting the order in which the main theorems are proved, ......... This book is destined to become a classic on the topic of coherence in complex analysis.'' (by V. Tosatti)
