The New York Times has an article about the status of ebooks in the library, both in the limitations that publishers are putting on circulations and a how-to for getting the books to your devices.
The author of the article talks about one trilogy having 193 holds. For a physical book, like the Hunger Games or the Gallagher Girls, that doesn’t seem like an insane wait list (when those first came out, my library had at least that many holds). It’s a long wait, but not insane. What makes it more interesting is that the article is talking about digital copies. There are no physical limitations here, just policy that the publishers are dictating.
