To enable OskiCat to remember your checkouts for you, please follow these directions. Please note, that if you do not opt in your history will NOT be saved.

  • In My OskiCat, find the button labeled My Reading History at the end of the row of buttons to the right of your name.
  • If you select the My Reading History button, you’ll go to a new screen which also has your name and other information in the top left, but which has a button labeled Opt In. Below this will be the sentence No Reading History Available.
  • Press the Opt In button and it will change immediately into a similar button labeled Opt Out with a red X.
  • You have now turned on the Patron History functionality and OskiCat will remember your checkouts.

You will also find four buttons:

  • Delete selected: Check the box to the left of the item.
  • Delete all
  • Opt out: In order to opt out, you must first delete all your entries. Deleting the entries cannot be undone. By deleting your entries and opting out, you will effectively erase all traces of your checkouts from the system.
