It's my own fault really. Not understanding the technology, I shouldn't have assumed; I should have checked the list of devices that I could use to read ebooks from my local library.
Kindle, my Christmas gift from my husband, is not one of them!
The Book Depository, my favourite online bookstore (because it has free shipping to Australia), also does not sell ebooks that can be read on Kindle.
I rarely buy books - the exceptions to this are gifts and craft books: I prefer those in printed versions so I can look at them over and over, in colour. Yes, I got one craft ebook for Christmas - I read that on my PC because the screen is larger so I could see the images in full colour but I would have preferred a "real" edition! (BTW, I'm not being ungrateful - I chose all four of those Christmas gifts myself and the ebook was the only format I could get of that particular book)
I had pictured being able to carry several books when I travel without the bulk of actual books. But I never planned on buying them: that's what my library membership is for, especially now I can download both audio books and ebooks (without leaving home).
So, what will I do with my Kindle?
