Save collection in iOS app for offline viewing

It would be really useful if the iOS app could cache your collection, even it was just book titles and authors, so that you could view them offline. It would also mean that you don't have to download the whole collection again every time you open the app.

I agree this is Needed! LT, please consider adding the ability for users to download their library for offline use.
I was at a large used book sale in St. Louis yesterday, and there was no wifi AND I could not access my cellular signal, even outside the building. I could not check if I already owned the books I found. If I could download my library as a backup for book shopping times, when I may not have access to the Internet, that would be a huge help!

Offline access has always been requested but has never been a priority from the developers. You best bet would be to export to a spreadsheet and save it to your phone.
