The question of how to work and Apple iBook on an iPad is really the question of how to utilize an e-book within this format. iBooks acts as an app for presenting and purchasing e-books, and you can either sync them from another source or download them from the iBooks Store. The basic issue of how to work them is then how the individual book is read and controlled within this format. This really breaks down to understanding how an e-book works and how it would work within the iBooks software and the iPad hardware. Here is a look at how to work an Apple iBook so that you can easily browse your favorite books.
The assumption here is that you have already been able to sync or download a book into your iBooks library. This is presented as a bookshelf and will have one or more titles there that you have available. To get started simply select the e-book title that you want to read. If your iPad is in landscape view it will pop up with two pages at a time, and if it is in the portrait view then it will simply do one page at a time in a larger presentation.
The logic of the e-book in iBooks is based on the logic of actually interacting with a regular physical book. When you press on the right edge of the page it will begin to turn, and you can see the other side of the page and the one following it. If you pull it quickly the page will flip quickly, and if you draw it slowly it will do so at the relative speed. This allows you to flip through pages at your own pace and will reflect the way you may flip through a physical book.
If you tap on the screen once you will get a series of different command options. In the upper right hand corner you will see an icon that is to letter As, one larger than the other. This will give you options to make the screen dimmer or brighter, change the size of the text, change the theme of the page presentation, or change the font. The intention of this section of settings is simply to make it easier for you to read, but does not change the functionality of the book.
Next to the As will be a magnifying glass, and if you choose this you will be able to enter in a word or a page number. This is intended to act as a search function that will allow you to find, and jump to, different parts of the book. This is very similar to how you may search a web page for a specific phrase. Within this you will also have the option to search the internet or Wikipedia if it is not found.
One of the most interesting functions is to the right of the magnifying glass, and looks like a little bookmark. When you press it a red ribbon will appear in the upper right hand corner of the page, and this will signify where you are in the book so you can easily jump back there when you leave and return.
The upper left hand corner has a link both to the Library where your books are stored and a little list icon, which takes you back to the Table of Contents. When you are in the Table of contents there will be a Resume button in the upper left hand corner that will take you back to where you were in the book. In the Table of contents you will have different options depending on the book, but often you will have the contents, a place to jump to the different locations where you have put the bookmarks, and then a place for notes. When you select a section in the Table of Contents it will jump to that place in the e-book.
At the bottom of the e-book presentation, as you are reading, it will list what page of how many you are and how many pages are left in the chapter. There are no page standardizations in the iBook world since you can change theme and text size, which can alter the number of pages there are. There will also be more pages in a book when it is in the landscape view than when it is in the portrait view since the pages are much smaller.
PDFs do not have such a wide range of features since they are essentially documents that are just made viewable through iBooks. iBooks makes these documents easier to read because of its presentation, but the detailed controls are not available since they are not actually e-books. You will still be able to control things like screen brightness, but not text size. You can also easily email or print them using a built in share button. Bookmarking and searching will work, but will be more open to error and will be less specific than with an e-book.
This is really only a very basic understanding of how to work an Apple iBook since many books add different features and many are becoming interactive because of the new creation tools available through the Apple App Store. This is the basic functionality of how to work one of these books, and it is important to remember that they can be opened up and put down at random since they stay saved to your iPad and accessible through the iBooks app.
