Libby app
Upon first logging into the Libby app, the timeline will be enabled by default, whether the reading history is turned on for the account or not. This will record any checkouts borrowed through the Libby app. Any future checkouts made by that user account outside of Libby, such as through the OverDrive website or directly through the MHLS online patron catalog, will be synced in the app to have a complete list going forward. There is not a way to restore activity to the timeline from before the patron installed the Libby app.
If the user does not want their activity tracked, they must opt out – see this page for more information. The user may also wish to clear their existing activity by using these steps.
OverDrive website (mhls.overdrive.com)
To access reading history on the OverDrive website (mhls.overdrive.com) the patron must opt-in. This can be enabled at any time, however, it will only keep track of checkouts from that point forward. There is no way to retrieve reading history from earlier if the setting was not yet turned on.
