Yes Joel... do a book. I bought two lay-flat photobook coupons (buy now, make book later) for Christmas. A 14"x11" and a 11"x8.5". I'm guessing you can do better. You've got so many high-quality shots of birds I'm sure you can get a bird book published.

Someone at work just bought an M-disc drive last week. He said it was surprisingly inexpensive. He got the one for 25GB disks, blu-ray BD-R compatible. Not sure what makes it special over other BD-Rs. A quick look at the MDisk site, and I see there are also 4.7GB (DVD size), 50GB (dual layer BluRay), and 100GB (quad layer bluRay). They're all rated for 1000 (roman numeral M) years, but I doubt you'll still find a compatible reader in 1000 years.

I see they're just over $100 on Amazon for one that's external, supporting USB3, and does BD-25, and DVD. The advantage of the external over SATA is that you can attach to PC, Mac, Laptop, whatever. The advantage of BD + DVD is you can give DVD discs to friends/family/clients who may not have a bluray drive.

That does seem like a decent option... but make yourself a book too.
