how do i delete a recommendation for purchase.
Thanks for asking! There is no mechanic for deleting a suggestion for purchase. If, after listening to it, you found the title wasn't particularly good - there's a reason why recommendations are reviewed by our collection development staff before purchase. And at any rate, there may be other users who would be interested and enjoy the title regardless of its quality.
If you're asking because you've hit your five recommendation cap for the month in MyOPL, your count will reset automatically with the turn of September - so it's just a few days anyway. If you were using the Overdrive suggest a purchase in ebooks.omahalibrary.org or your Overdrive app, there's no cap and no harm in leaving it be.
Thanks for using AskOPL!
