Got this question in the comments yesterday, and since it’s an inquiry I get often, I thought I’d pull it up into a post here:
“Why have the Martha, Charlotte, Caroline and Rose books gone out of print? As a huge fan of Laura’s books I read all the books and the books about her family. Now being older I want to purchase them all for my own collection as the libraries are getting rid of them. It does not help that I am Canadian and have a hell of a time of even finding them! Do you know of any places that still carries them?”
When a publisher allows a book to go out of print, it pretty much always means one thing: the book isn’t selling very well anymore. Warehouse space is extremely expensive, and there’s a certain point when it becomes more costly for a publisher to store books that are selling slowly than to just remainder them.
The decision to shutter the Little House prequels and sequels happened before social media took off, so if HarperCollins ever decides to bring them back (particularly as ebooks, which has been discussed but doesn’t seem to be happening anytime soon), we’d be able to give them a nice big push and I think they’d do very well.
You can sometimes find used copies on eBay or Amazon Marketplace, but they tend to be extremely expensive in those outlets. (I don’t get royalties on used book sales, so please know those crazy prices don’t have anything to do with me!)
