Thanks Duke, they definitely are and I checked quite a few out a while ago - it's great they've put that together. The direction I was going is access and ease of use. The museum is a Website not an app, which for some might make it less accessible, not to mention, to read any of them you have to download each book. Of course some might just prefer the website, which is fine, but others might see the app as much easier to navigate and convenient. The streaming of each really makes it nice. I know for my dad he hates having to wait for things to download and prefers streaming, but others probably don't mind at all.
Thanks again duke for the reply. Have a good day.
