200 years is not much for getting good books. You'd think 1 generation would be enough but it isn't. 200 years will produce a few great works, and with some luck a few masterworks as well, but the vast majority of books on the dwarven and human caravans will be amateurish, or good but not quite good.
300 years of worldgen and upwards will see more and more great and masterwork books.
In other news: year 12, 26 dwarves, 43 pets and livestock, no guests (those spies that dripped in despite no visitor locations stopped coming after two atom smashings, possibly related to the elf civ declaring war on me).
FPS still at 72 out of 72. Amazing. Caverns not breached. (I have to admit, when the dwarven and human caravans are pathing to and fro my depot, my FPS drops to 68-69)
I suspect my constant clearcutting of the surface trees might be a big contributor, as well as not breaching the cavern with all it's trees.
Sometimes I wish there was a side branch to the DF releases that still had the old 2d trees, for those of us without supercomputers.
EDIT: ofcourse the fact that EVERYTHING in my fortress is neatly quantum dumped into carefully designed mine cart operated quantum stockpiles with take from link only orders, and I have no storage bins or barrels at all also helps a lot.
EDIT: oh one question there: Is it possible to quantum dump stockpiles with filled containers like dye bags, and honey jars?
