Query: An outstanding three-volume source on Application Frameworks

I would like to congratulate the authors of three volumes on Building, Implementing and Domain specific application frameworks on an extremely well done job. I found the three volumes to be an invaluable and comprehensive source on application frameworks. These volumes cover all aspects pertaining to frameworks including models of development, key technical and business issues surrounding building of frameworks, experiences, lessons learned and successful practices to mention a few.In my opinion the three volumes are a must read for any software engineer who has been using or developing frameworks and as essential for software designers who want to be introduced and train in this area. The building volume is in particular attractive as a textbook for an advanced course on application frameworks.
