I started collecting hard cover gardening books before the internet was what it is today. These books have given me endless pleasure and ideas over the years. The internet can't be beat for rapidly honing in on specific information, but I still love to curl up with my hard cover gardening books. Now with Amazon, as you mentioned, you can find them at bargain prices. I don't know how I've missed Christopher Lloyd all these years and will probably get 'The Cottage Garden" and a few others that look interesting. I have a big reference picture book on Irises, but can't remember the name. I remember that I got it years ago at a book store that was a short walk from the surgery center where I had taken my brother in law for knee surgery. It was in/out ACL repair, but it was most of the day, and perusing that Iris book was a good way to spend the waiting time.
