What is different online book (IR) from ordinary e-book (EC), is becoming increasingly common in recent years?
EC comprise generally all the information (text, images). Therefore, the volume of these books is great, and during the transfer may have problems. Internet book meant to be read when connected to the Internet. Necessary files containing images downloaded from the Internet in the process of opening files from the main text. Therefore, the scope of Internet books considerably less than the volume of the electronic book. The necessary files are copied, not all at once, and in turn, it does not require high-speed transmission and a long continuous connection. After the first opening of the IR image files stored on your computer and read later, they are loaded from the disc, and you can see them even when off the internet.
Another advantage of this book is that it contains a large number of links, and as you read, you can switch to the original sites and supplement the information with information from primary sources.
