First of all, very thanks to you for your suggestions. But I think, you do not know about me and my difficulties and also my problems. I am basically from Pure Mathematics not from Applied Maths nor physics. I wish to read good books on Cosmology, thats why I have requested for such books. One another thing is that I like to read hard copy of books and I do not know which book is basic on cosmology. Also, Google is not as believable as books ( in my opinion). Unfortunately, I was not seen my question before asking that it is grammatically incorrect. Further, I request you that if you can not help some one in a proper manner then please not give a silly suggestion. Thanking you.
....got it from google only, and the information given is completely correct! See attached two links. Another method is to browse the "amazon.com" webpages of the respective books and go through the reader's feedback and rating. And, then pick as per your suitability. That is a better place to figure out your queries than posting such questions in a "research" forum.
However, your query is wisefull, although suggestion for google search "only" is not good suggestion. I think that there are many search engine.But my opinion is that a person who read some books on cosmology is more expert than google. He is able to tell that a particular topic has better explanation in a book and which topic has not been better explained in the same book.
