I'm assuming here that you are using Fortran 90 or 95 ( not 77 ). If you aren't using F90/95... I highly suggest that you start using it.
Fortran for Scientist and Engineers ( I think this is the title, my books at home )
by Lahey, Ellis, et al. This book is pretty good for beginners I think.
Fortran 90 Handbook by Brainard, Adams et al
Fortran 95 Handbook " " "
Upgrading to Fortran 90 by Cooper Redwine ( I don't have this one, but is very well
liked by others )
Fortran 90 Explained ( I think that's the title, I don't have this one either )
by M. Metcalf, this book is also very popular
