Books in Library

ok so I'm in the library and why wont he pick up the books? which is the blue book he takes first ,what color are the other books it is in with? Hes got his hand open and I click and click and he just wont take the book. Help ,,what am I doing wrong!

I think that the first (blue) book is on the floor. Each time you a replacing a book with a book of the correct colour.
Once you have the blue, there should be a green in the blue set to swap with, and so on.

I'm having trouble picking up the first book behind the piler help. I have the stragey guild but does not tell you how to pick up the book.

I am also having a problem here. I got the blue **** and it gave me a green book. I can't put the book in with green books. I went back downstairs and moved around and went back upstairs and I still can't get rid of the green book. What am I missing?
