Some iBooks Author Thoughts

I have been working in iBooks Author and finding it fairly good for basic tasks. However, the moment you want a bit extra from the program, it does fall short. Then again, the ePub 2 format also falls short in numerous areas.

The ".iba" (iBooks) and ".epub" formats are nothing more than standard compressed "zip" files containing various folders and files of HTML, images, fonts, and more. The structures are well documented, but not simple to edit and update without a good tool.

Let me acknowledge that some of the "problems" I experience with ePub/iBook formats are limitations that will require some re-imagining of the book format. The issues arise because eBooks in various formats are designed to allow the *reader* more control of content than the designer. The eBook concept is reader-centered, not designer centered.

The reader can change orientation (portrait vs. landscape), magnification, typefaces, font sizes, and screen colors (inverse, for example, when white-on-black is preferable than black on white). With everything a reader can do, the layout of a book is dynamic, not static.

My mind is already pondering how eBook generators could be improved.

A dynamic book, at least with current tools, cannot display footnotes or marginalia easily. My opinion is that references should "pop-up" the full citation, which for now means coding in HTML. I'd prefer an easier method that not only adds a pop-up, but it would be great to add citations to a bibliography and include links to works available via various booksellers.

I suppose a simple script can be added to the eBook pages, just like you might use for website pop-up definitions. I'll certainly be testing the idea for my current projects.

The dynamic pages also make indices difficult. You cannot link to "page numbers" because the numbers change. For now, creating links to anchors within the text is the best solution I can imagine. Links are not a perfect solution, but they are a solution.

Again, hand-coding links is not horrible, but can't this be automated? The programming logic is straightforward: given a word or phrase, find it and create a link. The text of the link could be the chapter and section numbers, since page numbers won't help readers. An example index entry might read: Fonts; Ch 1 Sec 2, Ch 2 Sec 1. It isn't as convenient as page numbers at first glance, but remember that these would be hyperlinks to the anchors. I plan to use this approach for a book we're converting at this moment.

To use the "anchor" approach, you do need to keep track of anchors somehow. I suppose the anchors would be something like this: "#fonts_1", "#fonts_2", and so on, incremented for each new occurrence of the indexed word and not associated with a chapter or section since text can be moved. The index generator would have to track locations, though.

Most eBook generators create decent tables of content, but they don't easily generate tables of figures or lists of tables. I'd like those features, too. Yet more "auto-generation" based on anchors, ids, and styles, I would suggest.

None of the missing features would be difficult to add to eBook generators. Already, iBooks Author includes a glossary tool. Why not add some of the other common textbook features?

Once the features are added, let's do something about the pain and misery required to create custom templates. Why don't the eBook tools, including iBooks, do a better job with the CSS they generate? I've used Pages, InDesign, Sigil, and iBooks to create eBooks. I've also used Scrivener. Without question, the bare minimum ePub generated by Scrivener was the best of the bunch — because it was simple. I used the Oxygen XML editor to tweak the CSS in a Scrivener ePub and was pleased.

We all mix-n-match software applications for the best possible results. We create images in Illustrator or Photoshop, edit long texts in Word, and finish the layout of a book with InDesign or QuarkXPress. But, I consider the CSS aspect of eBooks similar to the styles of InDesign or Word. Why should I need another program to tune simple CSS, with only a handful of styles?

In time, iBooks Author and similar tools will add the features I want. Even with fine-tuning and hand-coding, eBooks are much easier to create and distribute than traditional printed books.

What I Studied in Graduate School

Curiously, beyond the theses and dissertation, all my work is in economics of media and narrative. I ask what works and why when offering stories to audiences. What connects with an audience and can we model what audiences want from narratives? (Yes, you can model data on narratives and what "sells" and what wins awards and what nobody wants.)

Yet, my degree research projects all relate to design of writing spaces, as knowing what works is also key to knowing what could be "sold" to users.

Comic Sans Is (Generally) Lousy: Letters and Reading Challenges

Specimen of the typeface Comic Sans. (Photo credit: Wikipedia) Personally, I support everyone being able to type and read in whatever typefaces individuals prefer. If you like Comic Sans, then change the font while you type or read online content. If you like Helvetica, use that.

The digital world is not print. You can change typefaces. You can change their sizes. You can change colors. There is no reason to argue over what you use to type or to read as long as I can use typefaces that I like.

Now, as a design researcher? I'll tell you that type matters a lot to both the biological act of reading and the psychological act of constructing meaning. Statistically, there are "better" and "worse" type for conveying messages. There are also typefaces that are more legible and more readable. Sometimes, legibility does not help readability, either, as a type with overly distinct letters (legibility) can hinder word shapes and decoding (readability).

MarsEdit and Blogging

MarsEdit (Photo credit: Wikipedia) Mailing posts to blogs, a practice I adopted in 2005, allows a blogger like me to store copies of draft posts within email. If Blogger, WordPress, or the blogging platform of the moment crashes or for some other reason eats my posts, at least I have the original drafts of most entries. I find having such a nicely organized archive convenient — much easier than remembering to archive posts from Blogger or WordPress to my computer.

With this post, I am testing MarsEdit from Red Sweater Software based on recent reviews, including an overview on 9to5Mac.

Composing posts an email offers a fast way to prepare draft blogs, but the email does not always work well if you want to include basic formatting, images, and links to online resources. Submitting to Blogger via Apple Mail often produced complex HTML with unnecessary font and paragraph formatting styles. Problems with rich text led me to convert blog entries to plaintext in Apple Mail and then format th…
