LINQ best reference to read

My confusion comes from that I've read a book on ASP.NET it was Beginning ASP.NET 4.5.1 in C# and VB - Imar Spaanjaars and while reading it every time the author telling the readers that if they want to know about an issue or topic in more detail they can pick up another reference Professional ASP.NET 4.5 in C# and VB - Jason N. Gaylord, Christian Wenz, Pranav Rastogi, Todd Miranda, Scott Hanselman. When I checked that referred book, I found it indeed better and more detailed than the one I was reading from and containing topics the book I am using did not mention anything about them. If we compare the number of pages/chapters the first one is about 754 pages and 19 chapters while the second is 1331 pages and 35 chapters, in addition to, its appendix sections talking about useful topics too. Since that I am confused picking up any resource to read from not just in LINQ but in other things HTML5, CSS3, JavaScript, jQuery, ASP.NET Web API, Ajax, and even C# for example which better to read from C# 6.0 in a Nutshell or C# 6.0 and the .NET 5 Framework, 7th edition?. So I am trying to ask hoping that someone can giving an advice/tell me about which reference is better to use because it is more detailed or having that section explained better than others etc.
