Briefly introduce the definition.
According to the definition of the General Administration of Press and Publication, e-books refer to publications that digitize information such as words, pictures, sounds and images, and handheld readers that integrate storage media and display terminals into or download digitized information such as words, pictures, sounds and images.
It consists of three elements:
(1), the content of e-books, mainly produced in a special format, can be spread on wired or wireless networks, and is generally organized by special websites.
(2) E-book readers, including desktop personal computers, personal handheld digital devices (PDA) and specialized electronic devices, such as Hanlin E-books.
(3) e-book reading software, such as ADOBE Reader of Adobe Reader, Glassbook of Glassbook Company, MicrosoftReader of Microsoft, S SReader of Superstar Company, etc. It can be seen that both the content of e-books, reading equipment, reading software and even online publishing of e-books have been labeled as e-books.
According to available data, China has become the second largest e-book market in the world. In 2009, the shipment of e-books in China reached 3.82 million units, accounting for more than 20% of the global total in the first half of 20 10, second only to the United States, and it is expected to reach 965,438+10,000 units in the whole year!

classify
E-books generally have two meanings, one is e-books, and the other is hand-held readers specialized in reading e-books. The main formats of e-books are PDF, EXE, CHM, UMD, PDG, JAR, PDB, TXT, BRM, etc. At present, many popular mobile devices have the function of e-books. The mobile terminal can support the reading format of e-books. Common e-book formats are UMD, JAR and TXT.
E-book is a portable handheld electronic device, which is specially designed for reading books. It has a large-screen LCD, built-in Internet chip, and can easily buy and download digital books from the Internet. The large-capacity memory can store a large amount of digital information, and it can store about 30 traditional books at a time. Specially designed LCD technology can make people read comfortably for a long time.
E-books are portable, easy to use and large in capacity, which is very suitable for modern life. With the development of digital copyright trade and internet technology, users of e-books can easily buy more books at lower prices, which lays the foundation for the popularization of e-books.
Will e-books really bring new reading methods in the network age, and can they really replace traditional reading methods?
function
At present, there are many PDA products in China, which can be roughly divided into three types according to their functions:
First, it focuses on learning, and there are various English-Chinese translations and dictionaries, such as Yi Lian and Su Lian.
Second, business games are the main functions, such as notepad, calendar, exchange rate, stock market, sending and receiving emails, games and so on. , such as business communication, managers, celebrities, etc. Third, PDA, wireless Internet access, WINDONSCE operating system ... At present, some PDA products have added the function of reading e-books, although it is still not perfect. After all, e-books are still in their infancy, and many of them are waiting to see, waiting for the opportunity and ready to go.
There are SOFTBOOK, ROCKETBOOK and MICROSOFTREADER abroad, but there is no complete e-book product in China at present. Can it be developed, can it be compatible with PDA, and can it be developed with reading as the main function? At present, domestic e-books mainly include Foxit e-Slickbook and Hanwang e-books.
Third, you can subscribe to a variety of electronic periodicals, books and documents, automatically download the latest news and periodicals from the Internet, display full-page text and graphics, and enhance the reading experience through search, annotation and hyperlink. The page turning system is adopted, which is similar to the page turning of paper books. You can download online e-books to e-readers at any time, and you can also store your books and documents in e-readers.
The difference between e-books and e-books
In short, e-books contain the functions of e-books, and there are other functions:
1. E-books can not only "read" but also "write". E-books generally have thousands of e-books, and also have the original handwriting function, which can annotate books, take handwritten notes, handwritten emails, remotely sign and so on.
2. E-books also have functions commonly used in mobile internet device, such as surfing the Internet, mobile office, stock trading, GPS navigation, playing games, chatting on QQ, showing movies and listening to music.
At present, Guangxuntong has launched an e-book before Microsoft.
Performance overview principle
E-books, also known as e-books, make the contents of books into electronic versions and sell them online. Buyers use credit cards or electricity.
After payment, the sub-bank can download and use a special browser to read offline on tools such as computers that can add reader applications, such as mobile phones and electronic paper. E-books are different from free online reading on the Internet. They are the latest books released simultaneously with paper plate making, and you have to pay a certain fee to read them. Unlike CD-ROM books, e-books are bought online.
Functions of e-books: You can subscribe to a variety of electronic periodicals, books and documents, automatically download the latest news and periodicals from the Internet, display full-page text and graphics, enhance the reading experience through search, annotation and hyperlinks, and adopt a page-turning system, which is similar to the page-turning of paper books. You can download online e-books to e-readers at any time, and you can also store your books and documents in e-readers. E-books are electronic versions of traditional printed books, which can be read by personal computers or e-book readers. E-books are popular because they allow operations similar to paper books-readers can bookmark a page, take notes, reverse select a paragraph, and save the selected article.
In addition, the e-book reader also includes a built-in dictionary, variable fonts and styles. The main formats of e-books are PDF EXE CHM UMD PDG JAR PDB TXT and so on. Many popular mobile devices now support its reading format. At present, there are many books in PDF format downloaded online. For example, electronic bookstores currently provide such e-book downloads. E-books on mobile phones are becoming more and more popular now. Most mobile phones with readers support reading e-books in TXT format. Some mobile phones without readers, such as Nokia 5300, can also support reading e-books by installing specific software such as "MOTO TXT". The download of TXT e-books is mostly in the form of forums, such as "Hero Forum", which is a community with relatively complete resources and convenient download.
With the popularization of PC and the continuous progress of network teaching, electronic teaching materials have become a development direction of e-books more and more obviously. At present, the popularity of portable devices is far from enough, so the development of electronic textbooks is concentrated in colleges and universities. The development of students' built-in e-learning platform for teaching and supporting e-books is becoming more and more mature. I believe that in the near future, we will see them active in online teaching in primary and secondary schools.

Format introduction electronic paper books and e-books
E-books in a broad sense include electronic paper books, but in a breakdown, the definition of e-books does not include electronic paper books. The specific differences are as follows:
Simply put, the "electronic paper book" is an electronic reader, an electronic terminal, and more specifically, a small digital appliance that can be read; It is a new digital reader with electronic paper display screen. You can read most online e-books, such as PDF, CHM, TXT, etc. Compared with traditional mobile phones, mid, umpc and other devices to read e-books, e-book readers using electronic book technology have the advantages of less radiation, low power consumption, no harm to eyes, easy to carry and so on. Its display effect is realistic and looks just like paper books.
Generally speaking, e-books refer to "e-books", that is, digital publications. You can also understand them as books in PDF, DOC, CEB, TXT or picture format, which can be more directly understood as digital text content.
The relationship between electronic paper books and e-books;
1. E-book is a display platform for e-books, and readers can read the e-books in their hands.
2. E-books can be displayed not only on electronic paper books, but also on computers, mobile phones, pda and other terminals, which means you can read e-books on computers, mobile phones and other terminals;
3. Electronic paper books are also called e-book readers.
compare
Txt e-books, in fact, are electronic texts without any processing, and are the simplest display texts. Their codes are divided into ansi, unicode, unicode big endian and utf-8, which can be browsed normally in the computer. In our computers, ansi codes are commonly used, but mobile phones are different. Mobile phones generally default to unicode coding, and garbled codes will appear if the coding is not recognized. Of course, with the gradual development of mobile phones, this situation will be improved. In short, the easiest way to make a txt e-book is to change the encoding to the unicode encoding form when "saving" the conventional encoded electronic materials.
The advantage is that it is small in size and is the original carrier of various e-books. The disadvantage is that it has no function and is not beautiful.
Exe e-book, which is one of the most complicated e-book formats to make, is also the most beautiful and practical. The process is to split the content text in txt format into multiple TXT texts according to chapters, then make an html collection (page illustration and e-book cover) respectively, and finally make an e-book file with suffix. Exe packages software through e-books.
The advantages are beautiful and multifunctional, and chapter contents, page scrolling and tidy typesetting can be realized without any reading software. Disadvantages: the size of txt is relatively large, so it can't be read on mobile phones at present.
Pdf e-books are generally made by Foxit pdf editor, and there are basically two kinds: one is the text version, and the other is to copy the full text of paper books directly into pictures, which is the pdf e-book.
The advantages are intuitive, chapter catalogue, average appearance and average function. Disadvantages: among all e-book formats, pdf e-books are the largest, so you can read them on your mobile phone by installing a pdf reader.
Jar ebook, in fact, is to transcode the txt electronic text into unicod code, and then improve the function and practicality again through the mobile phone ebook making software, which is basically equivalent to the upgraded version of txt ebook.
Advantages Compared with txt, the bookmark segmentation function is increased. Disadvantages: it is limited to viewing on mobile phones, and its size is slightly larger than txt format, so it cannot be viewed on computers.
Advantages and disadvantages of various e-books
Which format of e-books is good? In fact, nothing is absolutely good or bad. There is no best, only more suitable. If you like reading e-books on your computer, I suggest you read e-books in exe or pdf format. If you like reading e-books on your mobile phone, I suggest you choose txt or jar format. If you want more details, I suggest you choose jar format. If you are an e-book lover, I suggest you choose exe e-books. There are many kinds of e-book networks mentioned above, among which TXT is a dime a dozen, such as starting a point and adding fragrance to tea. Exe format has fewer dots, such as 58L e-books, or worry-free. With the development of the times, our mobile phones will be like computers, or mobile phones and computers are basically equivalent to the difference between small computers and big computers. I believe that by that time, the so-called exhibition of any form of e-books will be Ma Pingchuan, and there will be no media obstacles.
Storage form
Faced with numerous e-book content providers and reading devices, it is necessary for us to understand some common e-book file formats.
E-book formats commonly used on PC
TXT file format This is a popular e-book file format, which is favored by many people, and there are also the most tools to make this format. Its biggest feature is that it is easy to read and do, and the e-books produced are also pretty good. This format of e-books is embedded with reading software, which can be read without installing a special reader, and has no high requirements for the running environment.
Before 2004, e-books in TXT format were mainly used to read text books, but there were some shortcomings in this kind of e-books. For example, TXT files produced by most related production software did not support Flash, Java and common audio and video files, which required the support of IE browser.
However, since 2004, electronic magazines and digital newspapers have become popular, adopting EXE format without exception, and supporting FLASH, multimedia and even scripting languages. The content of the exhibition is richer and the production is quite exquisite, which has become the most popular electronic magazine format at present. At present, digital newspapers, periodicals and books provided by Leap, XPLUS, ZCOM and other manufacturers under Founder Apabi all adopt this format.
Reading software: embedded reader, no need for additional reading software.
PDF file format
PDF (Portable Document Format) file format is an electronic file format developed by Adobe. This file format has nothing to do with the operating system platform, that is, PDF files are common in Windows, Unix and Apple's Mac OS operating systems. This feature makes it an ideal document format for electronic document distribution and digital information dissemination on the Internet. More and more e-books, product descriptions, company announcements, online materials and e-mails begin to use PDF files. At present, PDF file has become the de facto industrial standard of digital information.
