dotEPUB is a super-handy little tool that lets you quickly turn an article on a website into an EPUB file for reading as an ebook. I discovered it when I was looking for a way to store a Science article (behind paywall) for later reading. Worked like a charm. Just drag the bookmarklet to your browser toolbar and you’re good to go. There is an option for keeping images or leaving them out. My blog post on halos has too many images to be included, but otherwise the blog posts look great as well.
