Rothman and Greenland; Modern Epidemiology 2nd ed 1998 .Lippincott Raven

I think there may now be a 3rd ed.

actually the 1st ed is also very instructive in fundamentals.

I can highly recommend"

Advanced epidemiology: Epidemiology: Study design and data analysis by Mark Woodward 

thank you mr adrain,james and kahled,but the books that you reccommend was not acess freely.

Melese Linger , you can download it freely but to read it only online I think in CDC you can`t with this book because it exceeds 5 Mbs

well your best literature depends on whether its academic discourse or you have a specific problem you wish to study. for most epidemiology study look the field epidemiology course by CDC online ( centres for disease control)it will give you theory and current experiences in the field
