    What are Standard Adobe eBooks?

    Standard Adobe eBooks are Adobe .pdf or .epub files and can be supported on many different platforms. Most handheld devices (Kindle, iPad, Nook, etc.) have an eBook reader installed that supports .pdf and ePub files. We recommend Adobe Digital Editions or Bluefire Reader. Follow the directions for downloading Adobe Digital Editions and/or Bluefire Reader for an Android/I Pad, Pod, Phone, or Kindle Fire.

    Standard Adobe eBooks are still copyrighted. Each eBook purchased is licensed for one customer at a time and may not legally be shared with other users.

    What are Secure Adobe eBooks?

    Secure Adobe eBooks are pdf or ePub files protected with Adobe eBook Digital Rights Managment (DRM), which is the industry standard eBook security platform used across a wide variety of booksellers and public libraries. Secure eBooks are restricted for use on up to 6 computers/devices, including Windows PCs, Macs, i Devices (iPad, iPhone, iPod Touch), Kindle Fire, and Android readers. Some secure eBooks (depending on the publisher’s requirements) are further restricted to not allow printing or the use of copy/paste functions. These restrictions, if they exist, will be noted on the description page of each eBook.

    Before downloading a secure eBook, you must install and authorize the free Adobe Digital Editions on your PC or Macintosh. Your eBook will then open on your device that your personalized copy of Digital Editions exists. For clear instructions, please see your individual device listed above.

    Why are some eBooks secure?

    In order to prevent file sharing and unauthorized usage, some publishers require their eBooks to be protected with a Digital rights Management system (DRM). For those books which are secured, consider it a condition of sale from the publisher. The book would not be available in digital format if it were not for this system.

    How do I know if my eBook is Secure?

    The product description of each eBook in our catalog states whether that book is secured and which publisher restrictions apply. You can also check your email receipt to see if your eBook is secure. If the title of the eBook you purchased includes the words ‘SECURE EBOOK’, it is secured.

    What is the difference between ePub and PDF eBooks?

    ePub is an ideal format for handheld devices because of its reflowable nature, which means that when you increase or decrease the text size, the text will arrange itself to fit your screen. It works well on PCs and Macs and will require you to open the file in the free Adobe Digital Editions software.

    PDF is a standard format for reading eBooks and retains the original design of each page, so you see on your screen exactly what the book designer intended. While a nice feature for technical eBooks with embedded tables and figures, it can be difficult to read on handheld devices with small screens because the text size can not be modified without zooming in/out on each page.

    A summary: Here’s a table that summarizes the differences between PDFs and EPUBs (as of 9/6/2011):

    FeatureEPUBPDF (viewed with a PDF Reader)
    Reflowable textEPUBs automatically reflow (and hyphenate) and are well suited for mobile devices.PDFs are written in concrete – remember, they’re based on printed pages, typically 8½ by 11, and (with many PDF readers) they do not reflow when enlarged. This can make PDFs difficult to read on smaller mobile devices. Note: Adobe Reader X and a few other readers give users the ability to reflow text; however, this feature is typically not automatic.
    Change the font and specify a particular font sizeEPUBs can do this.PDFs cannot do this on many PDF readers.
    Page turningTo turn the pages of an EPUB, users swipe horizontally.To turn the pages of a PDF, users scroll vertically, and because of bottom page margins, there are typically larger gaps between pages.
    Complex tablesWith EPUBs, complex tables can be problematic, and content or coding often needs to be tweaked to make these types of tables work.With PDF, although complex tables may not require tweaking, they are often difficult to read on smaller devices and pose problems (horizontal scrolling) when enlarged.
    GraphicsOn small mobile devices, graphics can be difficult to read in EPUBs.On small mobile devices, graphics can be difficult to read in PDFs.

    Can I return my eBook if I am unhappy with the product?

    eProducts are satisfaction guaranteed. If you do not like it, or it is not what you are looking for, it may be returned for a refund within 30 days of purchase. If your dislike of the eProduct is due to technical issues, we do ask that you allow us to help you troubleshoot to solve the issue before we process the return. Also note that with secure eBooks, a 7% license fee from Adobe Systems is included in it the purchase price. Because that license is not cancelable, your total refund will be 93% of the eBook’s price.

    Can I read my eBook when not connected to the internet?

    Yes. Both standard Adobe eBooks and secure eBooks can be read offline as soon as you download the programs and files.

    Can I change my allowed computers?

    Unfortunately, no. There is NO WAY to issue additional downloads, so please make sure you follow the above instructions before downloading your eBooks. You are allowed 6 computers/devices authorized to your personal Digital Editions. There is no way to add additional licenses, so please be careful when downloading your eBooks. Your devices will remember your previous location and any notes you might have written.

    Can I purchase secured eBooks for others?

    Yes, BUT remember that the first time the eBook is downloaded and authorized with an Adobe ID in Adobe Digital Editions, it belongs to that user. You can not switch users after the eBook has been opened the first time. Please make sure that before you click the eBook download link, Adobe Digital Editions is installed on that computer and authorized by the correct user. We can not reassign eBooks due to the nature of the software.

    Can I network eBooks or put them in a shared system?

    Unfortunately no, secure eBooks cannot be accessed via a network.
