I have searched the fora for "Overdrive", please forgive me if I've missed the answer somewhere:

One of the things that most delighted me about my switch from Kindle Paperwhite to Clara HD was suddenly having Overdrive available. I was so excited to finally have access to a local library's ebook catalogue. Then I discovered that both local libraries I have membership cards for offer Overdrive - is there any way top access both? I looked into Libby, but it seems to be an Android app, hence presumably of little use for my Clara?
