For those of us for whom a positive response to the question "to read or not to read? "Evident" now have to answer another question: "how to read? ". And the thing is that modern digital technologies have reached and this seemingly conservative areas of life, and traditional books, slowly but surely supplanted by electronic books. Of course, for true bibliophiles value of good old books will never be lost. Nevertheless, the reader (book-reader) more confident win back his place in the sun, and the answer to the question "how to choose an e-book" is not just topical, and even burning.

Thanks to his Majesty "Internet" we have the opportunity to use digital libraries, and access to a wealth of relevant and interesting books and magazines. But how to read from the screen is not very convenient (and habits affect) people invented a special device such as a reader, through which electronic text to read and user-friendly, and nice. But sadly, nothing is perfect, and readers (like the rest of digital technology) is no exception. Any electronic device has its advantages and disadvantages, and want to buy high-quality item. Therefore, let us learn that represent a book-reader, and how to choose an e-book, given its key features and characteristics.

What is a book-reader?

Beech-reader - a digital device for reading electronic texts. It is a device we call already familiar term "electronic book". And the name is a literal translation of the English term «Electronic Book» abbreviated «eBook». Any digital device performs certain functions. The main tasks of book-reader - the storage and reproduction of text and illustrations. Therefore, in the first case beech reader performs the digital information storage device, and the second - a conventional paper sheet displays this information (in this case, the text and pictures). In addition, a spoiled modern consumer wants a device has also added features that make reading comfortable, affordable price and guaranteed quality.

According to the basic book-reader tasks are defined and the criteria by which this device is selected:

• appearance, the overall size and weight;
• the size and brightness of the screen;
• formats text display;
• memory cards;
• the ability to download information;
• Long battery life;
• the ability to markup and bookmarks;
• Russification;
• ability to access the network;
• Price.

This is a major, but not all of the criteria for selecting the e-book. And, of course, that would have to choose, not all at once, and that was the most significant for you as a reader. And because the screen reader is intended to replace the book page, it is with him and begin.

Screen size

How to choose an e-book with a convenient screen? Choosing a reader, you have to decide by how big screen you need. First, the value of the screen determines the size of the page that it is able to display. Incidentally, unlike the pages of a traditional book, electronic page size is measured in words, not in inches. It is therefore preferable to start with the selection of book-readers, the screen of which accommodates at least one paragraph of text. It explained this requirement is very simple. We read, in contrast to the first-graders, no spell or even the words. An adult simultaneously reads multiple words, and even entire lines of text. That is why reading is convenient to see the multi-line text.

Equally important is the geometry of the screen, that is, its size in inches. These parameters determine the resolution of the screen. The most popular sizes screen reader six to eight inches with a resolution of 600x800 pixels. As a rule, this is quite enough. But if you have a need to read magazines with illustrations or texts in PDF-format, it is wiser to purchase a large-screen reader. It is important that when you scale the font is not distorted, and the text is clearly visible and readable.

Display Settings

In addition to the size of the display to the reader important selection criteria may also include a large angle of view, the anti-reflective coating, adjust contrast and brightness, and background color. These criteria have to be guided by choosing the type of screen: e-Ink or LCD (liquid crystal). E-Ink technology makes it possible to approximate the (visual) screen reader to the page of ordinary books. These screens even called electronic paper. Its advantages over LCD:

1. Significant energy savings, which spent only on "flipping" pages. "
2. A wider viewing angle than LCD TVs.
3. Less strain on the eyes.

One important caveat - this screen must be protected from direct sunlight. Otherwise, the image may disappear altogether.

The main advantage of the liquid crystal display can be called a backlight, which gives the opportunity to read the screen in the dark, and relatively low cost. But the eyes of these screens get tired faster, and the energy they consume much more. However, no backlight for the screen, there are special lamps for reading electronic books. In general, the screens without backlighting should have a good anti-reflective coating, in any case, more substantial than a backlit screen. Because the anti-reflective coating is necessary to ensure that the reflected light from the screen of the lamp or the sun is not blinding.

The background color of the screen - not unimportant parameter when choosing an e-book. Here the choice is determined solely by the personal preferences of the reader. Pure white background, of course, enhances the contrast, but at the same time can be annoying and even dazzle the eye. It is therefore preferable to select the reader not with white background of the screen, and with beige, gray, green, blue, short, comfortable for you.

The viewing angle should be such that it was not necessary to change the position of the screen while reading. The larger the screen, the larger the angle it should have.

Type of control

Type of control reader can touch (with touch screen) or mechanically. The touch screen makes the device more ergonomic, minimizing the number of buttons and keys. With such a screen is very convenient to make notes while reading, highlighting the necessary information directly on the screen. Therefore reader with touch controls can be recommended to those who buy it to read the special and educational literature.

For regular readers choosing newsreader artworks preferred device with mechanical control (keys, buttons or a joystick). After all, they are unlikely to be necessary taking notes in the selected text, and in terms of the reliability of these readers considered to be more durable.

Format conversion and Russification

The reader supports more formats, the better for you. Enough for a full reading deemed formats djvu, txt, rtf, fb2, html. Most readers perceive a limited number of file formats (text and graphics). This is done in order to help users share content and difficult they would be forced to buy e-books. However, some of the latest models of e-books make it easy to read texts such simple formats like txt or html (but the text of this format are no styles). Graphic formats presented in the book-reader, quite different from the standard, but almost all of them support the most common format is jpeg. There are e-books, which open the archived files (zip). There are readers who support audio formats, which is useful for language learning and listening to audiobooks.

To transfer files from one format to another (conversion) is a good program converters, which can make e-books (eg Book Designer). In addition, there is always the opportunity to transfer text from one format to another (supported by the reader) on the desktop.

Have Russification in the reader - is also one of important parameters. Russification function allows e-book to understand and reproduce the Cyrillic text, and also to represent the Russian-speaking menu.

With regard to the pdf-file on the reader, they are difficult to read. This is not because these devices are bad, but because of the peculiarities of pdf-format that is not designed specifically for reading. Files in this format often display an A4 page, which is larger than the screen e-book. So the reader is unlikely to correctly display these files, you will have to get used to reading ordinary text files.

Capacity and duration of the

Modern e-book reader equipped with built-in memory that can hold a small library. So, if one book "weighs" on average from one to five megabytes, then the reader with a 512 MB memory can store from hundred to five hundred books. I agree that this is not enough. And besides, most reader has the opportunity to expand the internal memory with additional maps.

As for the length of battery life, choosing reader, ask for a number of "flipping" pages he designed. Or, when it comes to models with LCD screen for a number of hours is calculated battery.
Additional features and accessories

By and large, all of the additional opportunities for e-books - is excesses, which only increases the cost. As shown, the more add-ons (often unnecessary), the lower the performance of the device. However, they need to know about (and suddenly come in handy!). So many, many modern electronic books allow you to:

• rotated text on the screen is rotated (function G-sensor);
• use the built-in dictionary;
• listening to FM-radio;
• use the recorder;
• connect to the network via Wi-Fi, and download information, bypassing the computer;
• search, bookmark, and rename files by using the QWERTY-keyboard.

So decide for yourself how these or other advanced features you need, and without which it is possible to do.

Choosing an e-book with all its additional features, be sure full equipped accessories:

• headphone (if the player);
• Charger;
• port for connecting to a computer (USB 2.0);
• cable for connection to a computer;
• Quick Start Guide;
• cover;
• Stylus (touch for some readers);
• memory card (if supplied);
• warranty card.

Appearance and dimensions

According to these criteria eBooks choose not difficult. If you buy a reader for reading electronic books in a very homey and comfortable atmosphere, its substantial size and weight do not matter. The main thing is to meet the requirements of the screen. However, read in the more extreme conditions, for example, in transport, choose thin and lightweight reader that is easy to hold in your hand and place in the bag.

As for the design and colors of the modern reader, it can be called perfect. Your choice will appear and business models in strict black color covers and elegant model, light colors and elegant and even extravagant design e-books.

Knowing how to choose the right e-book, pay attention not only to the main technical parameters, but also on its structural condition. The main thing that it was almost perfect. Because even minor damage can be fatal for your purchase, and you need a reliable and high-quality reader capable of replacing a solid library bookshelf.
