Please tell me how to implement letter categories in blogs

e.g   

A - B - C - D - E - F - G - H - I - J - K - L - M - N - O - P - Q - R - S - T - U - V - W - X - Y - Z

If i click 'A' then it should display the blog sites starts with A.similarly for all the cases.
But by default it should display all the blog sites with Pagination
Thanks in advance
