help regarding combinatorics I want to know if there is any good book or material that fully explains and fully covers all combinatorics.I even did not find even Kenneth H.Rousan for this.So can anyone tell me any Discrete Mathematics book or any material to fully  explain Combinatorics even to advance level.that provide classification to combinatorics problems(most important).
You say in a comment:


  I am interested in combination problems that contain-distribution of distinct/indistinct objects to distinct/indistinct people,also with type of partition not defined,unordered partition etc advanced level problems


It doesn't sound to me like you want a book that covers all of combinatorics. Combinatorics is a vast subject, which includes enumerative combinatorics, probabilistic combinatorics, extremal combinatorics, graph theory, and several other subdisciplines. It sounds to me like you are interested in a subarea of enumerative combinatorics.  

Richard Stanley's two-volume series on enumerative combinatorics is quite good, and I suspect it contains the material you want.
