As a forewarning, I’m not going to go too far into the various bookstore formats, other than to say that at the least you’ll need to start with a Microsoft Word or ePub file. While Amazon and the like will accept a Word file to publish, to ensure your book converts to the various proprietary formats, I recommend creating an ePub file as your base. EPub is the most common ebook file standard, and I think you’ll have fewer problems starting with that. Fortunately, the ebook creation apps I’m going to tell you about all export an ePub natively. While there are Automator scripts to convert text to ePub, by using these packages you’re pretty much guaranteed to keep your document formatting.

One quick note up front: I’m not going to include Apple’s own iBooks Author tool. That’s because my goals for this piece were simple: talk about ebook-making programs that can be used in multiple bookstores and create files that aren’t just static images of a page. iBooks Author creates static pages that can only be used in the iBookstore. That’s great for getting an interactive textbook into the iBookstore, but not so good for other kinds of books.

Pages

Apple’s Pages app ($19) is probably the most straightforward and easiest way to create an ePub file. You will need to use a Word Processing template, not a Page Layout template. Other than that, you pretty much just type, type, type until your Great American Novel is done. You’re going to want to use consistent formatting, taking care to use document styles while typing away, or you’re going to have to go back and reformat the thing. Document styles are important because an ePub file is basically an HTML file with some CSS formatting applied. Therefore, using the Body style for your body text, and the heading styles for your headings will make your life a lot easier come file export time, especially if you need to create a Table of Contents. This support article by Apple has some handy tips for using Pages to create ePub files.

Scrivener

If you’re a serious writer, odds are you’re already using the wonderful Scrivener ($44.99) by Literature and Latte. Scrivener is a sort of Swiss Army knife of writing programs. It’s very flexible, and allows you to essentially merge and move around text files to create a piece of finished work (be it a printed manuscript, file, or ePub file). I’ve used it for some screenwriting, where I want to change the position of a scene. Rather than cut and paste, I could just drag that text file to the place I wanted it. While you could just use one text file for your entire body of work, laying out your file similar to the screenshot below will allow you to take full advantage of the program’s offerings. It’s a fantastic way to work on bits of chapters at a time without worrying about mucking the whole file up.

Once you’re done, just go to the file menu and choose Compile and then choose whether you want to create ePub, .Mobi, or .iBook chapters.

Adobe InDesign

Yes, that’s right: I’m recommending a $699 page layout program to create ebooks. No one is more surprised about this than I am. When I was offered a briefing from Adobe on using Indesign for this purpose, I tried to put it off due to my preconceived notion that using Indesign to create ebooks would yield a result similar to a Zinio magazine: a big honking static PDF-type file.

I was wrong.

Indesign, as it turns out, is a pretty powerful ebook creation program. In short, you can take a file you’ve created a smashing page layout of and turn it into an ebook. You can adjust the typography and create an ebook that looks almost exactly like a printed book. It’ll even fairly easily convert your initial drop caps into something the ePub file can understand. If you really need your ebook to look its very best, Indesign may be the best option.

But Lordy it’s not cheap. InDesign is a full-featured page layout program that designers use to create all sorts of material (ads, books, flyers, etc.). At $699 if your books are just text you’re probably better served with Pages or Scrivener because Indesign’s strengths are in layouts combining images and text.

If you’re working on an ebook that’s, say, a technical reference book with a ton of images and you want it to look damn good, InDesign is worth the expense. I was thinking of working on such a project a while back; had I gone through with it, I likely would have reached for my credit card quite happily.

InDesign also has a serious learning curve. It’s not a program you master in a weekend, or, say, a week before a deadline. In my case, I used to run a pre-press shop so my InDesign knowledge was pretty good, albeit rusty.

The app I use

Right now I’m using Pages, for the simple reason that it also runs on my iPad, meaning I can use my lunch breaks at work to write. Literature and Latte is working on an iPad version of Scrivener, but it doesn’t sound like it’ll see the light of day for quite some time. So, an app that I can use on multiple platforms and sync via Documents in the Cloud wins. It also helps that right now I’m working on short stories and novellas, which are well within Pages’ means to handle.

We anticipate that over the course of an hour or so Cook and a variety of other Apple executives will introduce us to the rest of the company’s holiday product lineup. The star of the show, of course, is expected to be a smaller iPad. But that’s not all: the Mac is also set to play a role in the events as well.

Om Malik and I will be bringing you live updates and photos of the event as it unfolds. We’ll kick things off a bit before the event started at 10 a.m. PT, so please join us below.

In a rare move, Apple will also be live-streaming the event from San Jose: as long as you own an Apple product. Owners of iOS devices running version 4.2 or later or Mac OS X 10.6 users running Safari 4 will be able to watch the event, as well as some Apple TV users, according to a webpage released by Apple early Tuesday morning.

In the meantime, here’s a preview of the event.

Here’s what has been announced so far:

• A new version of iBooks. It has continuous scrolling, and works better with iCloud.
• A 13-inch MacBook Pro with the Retina display, which Apple introduced earlier this year in a 15-inch version. It’s thinner and lighter than the current 13-inch MacBook Pro, and costs $1,699. It’s available today.
• A new iMac. It has a much thinner display than the current iMac version, and will come in 21-inch and 27-inch versions for $1,299 and $1,799, respectively. They’ll be available in December.
• A fourth-generation iPad. It has a faster processor and will work on Sprint’s 4G LTE network. It’s the same size as the original iPad, and costs $499, just like the current-generation models.
• The iPad mini. We’re a little surprised they chose that name, but hey. It has a 7.9-inch screen and a 1024 by 768 pixel display. It’s a Wi-Fi only device, starting at $329 for a 16GB version, and cellular-network versions will also be available.
