Feng Shui: The Lost Island
Group with access to excellent records, a storehouse of knowledge, or an advanced computer system have this schtick. A Library can be a pile of scrolls from an old temple, a stack of computer disks, a room full of three-ring binders, or whatever. Every schtick in Library grants 5 skill bonuses to spend onInfo skills kept in the Library. Any character may access the Library, add her own Intelligence score to the bonuses in a given subject and make a skill check. This takes however long the GM says it does, but usually at least a couple of hours.
A Headquarters with a Library is nice, indeed.
