The book was packed with research papers but organized in a rather clear structure for easy navigation between knowledge graph research and agent (e.g. graph construction, indexing, and retrieval, memory, planning and reasoning, tool usage). I am reading the book in its early release format therefore there are quite a bit of stuff that read like confusion such as some repeated text, very sketchy demo code snippet. The papers also deserve better illustration as some of their description are scattered around so it is not so easy to follow. But overall it is great
