Good evening, I am currently taking a class which has combinatorial designs as the first topic, we are using Peter Cameron's book Designs, Graphs, Codes and their Links which I am finding extremely interesting. I am really interested in a rigorous study of combinatorial designs without their links now.Of course I plan to continue taking the class, but I would really like to read a textbook just on designs (I am especially interested in realizable designs (like the social golfer and Kirkman girl problem)).

Thank you very much in advance.

Regards.
