I just found a possible name for what I was looking for: Piano Bookholders.
Here is one, which requires drilling:

Can you not simply use plastic/wooden clips - something like
this? I rarely have problems with music not staying open (I generally use force until they do

), but these do the trick (and they're cute!

)
Oh these are so so so sweet! I know they are regular clips, and work the same way as the clothes pegs mentioned by fabnt, but oh how cute!! I would love to have the fish and the cat. Too bad I am not in UK, but you have given me an idea... I could look at the stationery shops for similar clips. But they don't really hold the thick books open, do they? How large is each clip?

I'm afraid my solution is to be fairly brutal with the book and 'break' the spine so that the music lies flat. It is fairly useless otherwise. I have occasionally taken a book to pieces and reassembled it with a comb binder (a bit drastic I know, but it works...) I would rather adulterate the music than my piano!
I have thought about it... but I don't have the heart to. The fact is, my books usually disintegrate within a few years of intensive usage. I am a very careless and clumsy person. So I am actually trying to keep the books intact, rather than rip them apart.
I realise that Schirmer's books are really good, as they lay quite flat. Of course, they are prone to ripping apart. SueHM, have you already de-spined a couple of Schirmers? My Czerny's School of Velocity is already in 3 pieces, due to natural forces ...
I just had an idea while looking through my stationery. Eldatom, shall we try these out?Office Foldback ClipsMy guess is that if we have two of the above clips clamped to the front of the music desk, with the top metal "leg" lifted up, maybe they can stop the books from closing/flipping. I haven't tried yet, as what I have at home are too tiny.
I foresee a few problems:
1) The "legs" might not be stiff enough to resist thick books. They are likely to fold back, unless some modification is done to limit folding back. Maybe some plasticine at the hinges?

2) Clamping something metallic to the music desk might scratch the polished surface. What I can think of would be small pieces of soft felt to protect the music desk.
3) Always a problem would be turning of pages. Theoretically one hand will be sufficient, since the "legs" can be folded back. Practically, who knows?
OK, just another of my crazy ideas... Are there any more similar clips with springy/bouncy extensions/legs i.e. will spring back to the "lifted" position after being pushed down during a page turn?
