Where can I find a guide to the Library Quests? I keep losing money on them. Thanks!

Idk about a guide, but I usually don't go over 5,ooo x the # of items.

i rarely do those, and only one item, and if it doesnt go over 5k....

i only try it for the tiered achievements for it :P

I hate the Library Quests. sometimes he gives me more sP than I spend, but a lot of times he gave me like 800 and I spent...2000? Ugh
