I've started to study Behind Bars by Elaine Gould. "The definitive guide to music notation", according to the subtitle. And in a foreword Sir Simon Rattle affirms this view:

"Elaine Gould, in this wonderful monster volume, has written the equivalent of the Grove Dictionary for Notation. It is an extraordinary achievement, and if used by the next generation of composers and copyists will be a blessing for hard-working and long-suffering performers everywhere! Every chapter presents solutions and rules that will make our life easier, save rehearsal time and frustration, and will ultimately lead to better performances. What is important for a musician is to be able to spend rehearsal time on the music itself. I not only welcome her book unreservedly, but I would also pray that it becomes a kind of Holy Writ for notation in this coming century. Certainly nobody could have done it better, and it will be a reference for musicians for decades to come."

My first impression is also very promising. I'm sure I will post some more during my reading of it.
