So I'm loading my iPad Mini with favorite stories. Stories that are on AO3 are easy: I download them as ePub files and then I can open them in iBooks.
Stories that aren't on AO3 were a bit more challenging. But then I discovered Pocket. Pocket captures HTML files and puts them on your mobile device so you can look at them when you have no connectivity. I've downloaded four files, and it seems to work like a champ. One of the great things about it, from my point of view, is that it downloads them as clean HTML with minimal layout, graphics, etc.
One problem is, it uses whatever the HTML page title was. This is not always a good thing: if the LJ or DW entry with your story was titled something generic rather than the actual title of your story, then the Pocket copy will be titled that way too. And there's no way to edit the titles, although that seems to be something that lots of users are requesting, so maybe someday.
Anyway ... this ends my commercial for Pocket. We'll see how it pans out when I put, say, all 27 chapters of "Cupidity" on the Mini.
