This book is packed full of magnificent music, and has been a standard in my choir for many years. Like previous editions, the pages are well bound and stay open with ease. From new, it can be opened on a surface ranging from flat to 70 degrees and no page will float up.
Unlike previous editions, however, the paper is thinner, and renders it harder to precisely thumb through - riffling to "Page 245" takes longer, and if your hands are dry, the final approach to the page itself can be frustrating. Corner-folding is less robust, since the fold will not stand proud for so long.
The print quality is as good as previous editions, but again, thin paper means that in some lights, some pages suffer from slight transparency.
For gentle use, such considerations are minor - I certainly do not want to subtract more than one point from the rating, but it is only fair to warn that in this edition, certain musical works may put the paper under strain. 'Quam Gloriosum' has several page-turns at moments of high intensity, polyphonic pieces are responsible for desperate page-flipping amongst the lost and unrehearsed, and, when hand-holding the book, the white knuckles and vice-like thumbs of basses bellowing, "Inaestimaaaaaaabile sacramennnnnntuuuuuuum!" in Bruckner's 'Locus Iste', impose their own form of jeopardy. Within my attempt at humour is the serious point that this edition imposes risks and difficulties when navigating in the heat of rehearsal or performance.
