Hi all,
I just discovered today that the Library of Congress has created an app that allows you to browse their digital collections on your iPhone or iPad (their site says an Android version is due later this year). You can read more here:
https://www.loc.gov/item/prn-20-032/ and find the app on your iOS devices by searching for Library of Congress collections. The app doesn't differ too much in functionality from their online digital collection site though there is a favorites section that allows you to save items from the collection for easy access.
