Also check with your local County Extension Agents, they often have great literature on tree i.d.
I will echo the sentiments from others about peeling white woods immediately and sealing the backs. Shellac, wood glue, cheap latex paint (buy dented cans, mis-tinted cans, returns, etc...always the cheapest!), shellac, polly-you're-insane, or anything like this will do the job. No need to blow big bucks, just something to slow down the evaporation of moisture from the ends or the back.
Pick the worse stave of the bunch, and start reducing it to clost to bow dimensions. It will dry faster that way, and with less experience under your belt who cares then if it gets boogered up!
Good luck, MuffinMan.
