Sources for Reading Material for Your BlackBerry PlayBook
The Kobo Books Reader is intended for use with titles that are downloaded from the Kobo site. That doesn’t, however, mean that this is the only possible source for reading material for your BlackBerry PlayBook.
Read PDFs on your PlayBook
To begin with, you can download copies of thousands of public domain (out-of-copyright) books that are stored as PDF files. When you get a book in PDF format, store it on your PlayBook in the Books folder. Then use Adobe Reader (one of the free apps that comes with the PlayBook) to open and read the book.
Here, you can see the famous opening chapter from Herman Melville’s Moby Dick, downloaded from a website called Planet PDF.
You may find it easier to search for and download PDF files using your personal or laptop computer and then use the USB cable to drag and drop the file over to the Books folder on your BlackBerry PlayBook.
Digital Rights Management files on your PlayBook
Other sources for books include public and private libraries, research institutes, and publishers that send their wares directly to the public. In many cases, files from these suppliers are given with Digital Rights Management (DRM) encoding attached.
DRM is used for several reasons:
To limit the transfer of a file. A license for a DRM file may state that it can only be used on a single computer or tablet and can’t be transferred to another person or device.
To set a time limit on use. As public libraries begin to offer digital downloads, many publishers are requiring the use of DRM schemes to prevent redistribution of a file and to limit the amount of time a book may be borrowed by a user.
Why put a time limit? For centuries, libraries have allowed users to check out a book and then asked for its return so that other readers can use it; a time limit on a digital file accomplishes the same thing, de-authorizing or erasing the file after a period of time.
To enforce copyright restrictions. A DRM license may keep someone from copying or changing a file, one of the key elements of a copyright placed upon it.
