Digital Trends’ eReader Buying Tips:

Book stores and App stores

Making sure your device has an intuitive OS is important, but knowing that it has the books that you hope to read is vital. E-readers are tied to a single store. Before buying an e-reader, visit the Kindle or Nook websites to search for a few books you may want to read. Does your favorite device have the books you want? If not, consider the competition.

What are E-readers?

E-book readers are devices designed specifically for reading text. They’re made for people who enjoy reading novels and other long articles. Most e-readers have monochrome E-Ink screens, which mimic the look of ink on paper. E-Ink screens are great at displaying text and easy to read in the sunlight, but can’t pull off moving video. Most e-readers don’t have a backlight either, so nighttime reading requires a reading lamp. Long battery life, low prices, and simple e-book store access characterize the majority of these devices. The Amazon Kindle and Barnes & Noble Nook are the most popular options.

There are versions that feature full LCD touchscreens and video like the Nook Color. Though an e-book reader at heart, the device has a seven inch, full color touchscreen and runs on Google’s Android OS, a smartphone and tablet operating system. It offers moving video, slick magazines, fast web browsing, doc and productivity software, and a small app store.

E-reader Formats

E-book readers accept many different types of formats. When looking for your new e-reader maake sure that you find out which formats they do and don’t accept. Below is a handy guide to the various formats.


Epub was created by the International Digital Publishing Forum. It is supported by most e-readers, so this one you shouldn’t have to worry about. The benefit to this format is that it is reflowable meaning that text is not formatted for one specific page size. This means that text size and format adjustments won’t look odd if you change them. When doing your ereader comparison, this format is very important and should be sought after.


Most documents and files on the internet are in the PDF format. The downside to using the PDF format on electronic book readers is that lines are a fixed length when the e-book was created, so sometimes when it converts onto your e-reader, the lines may not display correctly. Depending on what you are reading on your ebook, this may or may not be important to you. PDF is quite useful as an additional format in eReaders and you may want to include it during your ereader comparison.

Plain Text (TXT)

Plain Text is very rarely used, though it does exist.

Amazon Kindle (AZW)

This is the format that was developed by Amazon to work with their Kindle eReader. AZW files work with the Kindle and are purchased from the Amazon book store. This format only really works on the Kindle.

eReader (PDB)

This was created for PALM hand-held devices. It is not standard with the newer e-books readers.
This format will probably not work with your e-book unless it specifically says so.

Sony Reader (BbeB/LRF)

BbeB is used by the Sony Reader and it isn’t really supported by other e-readers or PC reading, though it supposedly can be read on Linux computers.

TomeRaider (tr2, tr3)

Barnes and Noble Nooks use TomeRaider, which is available on PCs, Smart Phones, iPhone and other sources but isn’t supported by Kindle or the Sony Reader. The Nook also doesn’t support as many formats as the Kindle and Sony Reader.

Choosing an OS

It’s very important to choose an operating system that is easy to use and intuitive for you. In e-readers, this means trying out devices (if possible) to see if you like the way each device navigates between books, chapters, and pages. Some e-readers, like the Sony Reader, require a USB connection to a PC to download books. If this is a problem, opt for a different device. If you’ll want new books while on the go or travelling, opt for an always-connected 3G device, like the Kindle.
