In my previous couple worlds I noticed that I had a hard time finding anything other than biome pages. So my next world I made had Twilight Forest and Biomes O' Plenty disabled.
I found most of the non-biome pages quite quickly in that world. It looks like Mystcraft assigns an equal chance to each individual page and randomly picks one from the entire list when you find a page. So the more biomes, the harder it is to find anything else.
