Robo­Help 10 makes it much eas­i­er to gen­er­ate EPUB files, the most wide­ly accept­ed file for­mat for e‑books. EPUB files can be read on an array of devices includ­ing the iPad, iPhone, and smart­phones run­ning on Android.

What is an EPUB file?

An EPUB doc­u­ment is a zip file with the .epub exten­sion. You cre­ate EPUB files using Microsoft Word, Adobe InDe­sign, and help author­ing tools such as Mad­cap Flare and Adobe Robo­Help. This blog entry explains the major steps of cre­at­ing EPUB files using Robo­Help 10, which was released this summer.

Advantages of EPUB

* Easy to pro­duce. Cre­at­ing EPUB files are easy to pro­duce with new­er author­ing tools.

* EPUB con­tent reflows. In Eliz­a­beth Cas­tro’s book EPUB Straight to the Point, she writes: “If you’re read­ing it (an EPUB file) on an iPhone, the width of the page is a fair bit small­er than if you’re read­ing it on an iPad, or on some oth­er read­er. The beau­ty of EPUB is that it flows the text to fit what­ev­er screen it’s on.” In con­trast, the pre­sen­ta­tion of a PDF file stays large­ly sta­t­ic, regard­less if you’re using a PC, a Mac, an iPhone, or an iPad.

* Can be viewed offline. Once you down­load a EPUB file, you can view it with­out an Inter­net connection.

Disadvantages of EPUB

* Nav­i­ga­tion is not ide­al. The EPUB file for­mat sup­ports a table of con­tents at the start of the EPUB file. But if you’re want­i­ng to skim the table of con­tents, you need to jump to the front of the doc­u­ment. A tra­di­tion­al online help sys­tem always dis­plays the table of con­tents, mak­ing it easy to jump to anoth­er topic.

* Best suit­ed to lin­ear read­ing. The EPUB file for­mat is fine for tra­di­tion­al books in which you read lin­ear­ly. Users of tech­ni­cal doc­u­ments do not read this way. They skip from top­ic to top­ic in an effort to find the answers they need.

* Extra app required. iBooks, Apple’s e‑reader app, is not pre-installed on the iPad. Users first need to down­load the free app before they can read EPUB files. Not a huge deal but it is anoth­er step for users.

Writing EPUB content in RoboHelp

I assume that you are famil­iar with Robo­Help so I don’t try to explain every option and con­cept in the soft­ware. I focus on what’s new in Robo­Help 10 and how it can eas­i­ly cre­ate EPUB files.

Step 1: Write your content in RoboHelp

Write your doc­u­men­ta­tion in Robo­Help as you nor­mal­ly would.

Step 2: Generate your content as an EPUB format

1. In the Sin­gle Source Lay­outs sec­tion, dou­ble-click eBook.

Step 3: Select your options

General section

1. In the eBook Set­tings dia­log box, click Gen­er­al.
2. In the eBook For­mats sec­tion, select the EPUB 3 check box. You can also gen­er­ate an out­put file that is com­pat­i­ble with the Kindle.
3. If need­ed, make changes to your out­put fold­er and file name.
4. In the Options sec­tion, you may want to select the Val­i­date EPUB 3 Out­put check box. An open source tool called epub­check val­i­dates your EPUB file.

Content section

1. In the eBook Set­tings dia­log box, click Con­tent.
2. In the Table of Con­tents drop-down list, select the table of con­tents that you cre­at­ed in RoboHelp.
3. In the Index and Glos­sary drop-down lists, select an index and glos­sary if you set them up in RoboHelp.
4. In the Con­di­tion­al Build Expres­sion sec­tion, change your con­di­tion­al text set­tings if need­ed. With con­di­tion­al text, you can tag cer­tain sec­tions of your con­tent for dif­fer­ent audi­ences or deliverables.

Meta Information section

1. In the eBook Set­tings dia­log box, click Meta Infor­ma­tion.
2. In the Title box, type the name of the EPUB file.
3. In the Author(s) box, type the name of the author. This may be your name or the name of your department.
4. In the Publisher(s) box, type your com­pa­ny’s name.
5. In the Descrip­tion box, type a sen­tence or two that pro­vides a good sum­ma­ry of your document.
6. In the Cov­er Image sec­tion, select the image you’d like to be on the cov­er on your EPUB file.
7. Click Save and Generate.

Step 4: Download Adobe Digital Editions

Adobe Dig­i­tal Edi­tions free soft­ware offers a way to view and man­age EPUB files and oth­er dig­i­tal pub­li­ca­tions. I think of it as soft­ware to quick­ly test your gen­er­at­ed file before trans­fer­ring the file to an iPad.

This step is option­al but could save you time if you intend to gen­er­ate mul­ti­ple EPUB files. When Robo­Help fin­ish­es gen­er­at­ing the file and you click View Result, you can imme­di­ate­ly view your EPUB file in Adobe Dig­i­tal Editions.

If there’s a prob­lem with the file, you can fix the issue and then quick­ly regen­er­ate the content.

Step 5: Transfer the file to an iPad

After you have gen­er­at­ed the con­tent, Robo­Help cre­ates the EPUB file in a fold­er that you specified.

To syn­chro­nize the file to an iPad, ensure you have iTunes installed on your com­put­er. In addi­tion, you need to install iBooks, a free e‑reader on your iPad.

1. Con­nect your iPad to your computer.
2. In iTunes, click the Sum­ma­ry but­ton and select the Man­u­al­ly man­age music and videos check box.
3. Locate the gen­er­at­ed EPUB file on your computer.
4. Drag it to your device in iTunes.

iTunes syn­chro­nizes the file to your iPad.

Step 6: View the file in iBooks

1. Open iBooks.
2. In the Library in iBooks, tap the file you just transferred.
   The EPUB file appears. Here is an exam­ple of an EPUB file that is dis­play­ing in iBooks.
