You can also open up the document style sheet. When you double-click on a chapter in the left navigation, it will open up in a new tab in the editing pane. Figure 2 illustrates each new chapter of a book. I also instruct Calibre to start a new page with every tag. For example: When I convert books, I always change the conversion wizard to search for the HTML tag to use as chapter headings. When you expand the text tree, you will see each chapter of your book (depending upon how you’ve handled the conversion). What’s important to note is, from within in the navigation pane, you can expand each tree to view individual entries. Preview pane (right) displays the contents of the book Work pane (center) is where you do the editing of the book To get to the editing window, right-click on the book you want to work with (from within Calibre’s main window-see Figure 1 above) and select Edit book.īook navigation (far left) is where you select what you want to view (chapters, styles, images, fonts, etc) With that said, let’s walk through the editing process of your book. I won’t go through the Calibre conversion process, so these steps assume you already have your book converted into the necessary format. azw3 formats (the Calibre editor cannot work with. Also, you must have converted your e-book to either. In other words, you’re not going to be editing a LibreOffice. The only caveat to this process is that it requires you have at least a basic understanding of HTML and CSS (as the editing pane works with both). You can even do the entire formatting within Calibre and bypass any errors introduced by a middle man. With this outstanding, open source e-book management software, there’s a lesser-known feature that allows you to edit your e-book, in real time, to remove those formatting (and other) mistakes with ease. However, that time-consuming process doesn’t have to be so frustrating… at least not when you have Calibre at hand. This can become quite tedious when you run into stubborn or numerous formatting errors that slip through the cracks. When you find issues, you then must reformat, save again, reconvert, and recheck. You format the book, save it, convert it, and check it out. If you’ve worked with e-books, you know that editing them can be a work-flow nightmare.
