You can easily enter past reading in the mobile app by following these steps:
1. Tap the + symbol in bottom center of the screen, select Reading, and select the accurate reader(s) if there are multiple readers on the account.
2. Then, search, select, or scan the appropriate title, and select Log Reading.
3. On the logging screen, click Change next to "Logging reading for Today" to select a past date. If your library or school restricts back-dated reading, you can only select dates up to 90 days in the past.
4. Select the correct completion status, enter the time and/or pages of reading, and tap Done.
