ABOUT E-BOOKS
An e-book (short for electronic book, also written eBook or ebook) is an e-text that forms the digital media equivalent of a conventional printed book, often protected with a digital rights management system. E-books are usually read on personal computers or smart phones, or on dedicated hardware devices known as e-book readers or e-book devices. Many mobile phones can also be used to read e-books. Early e-books were generally written for specialty areas and a limited audience, meant to be read only by small and devoted interest groups. The scope of the subject matter of these e-books included technical manuals for hardware, manufacturing techniques, and other subjects.
Numerous e-book formats emerged and proliferated, some supported by major software companies such as Adobe's PDF format, and others supported by independent and open-source programmers. Multiple readers naturally followed multiple formats, most of them specializing in only one format, and thereby fragmenting the e-book market even more. Due to exclusiveness and limited readerships of e-books, the fractured market of independents and specialty authors lacked consensus regarding a standard for packaging and selling e-books. E-books continued to gain in their own underground markets. Many e-book publishers began distributing books that were in the public domain. At the same time, authors with books that were not accepted by publishers offered their works online so they could be seen by others. Unofficial (and occasionally unauthorized) catalogs of books became available over the web, and sites devoted to e-books began disseminating information about e-books to the public.
As of 2009[update], new marketing models for e-books were being developed and dedicated reading hardware was produced. E-books (as opposed to ebook readers) have yet to achieve global distribution. Only two e-book readers dominate the market, Amazon's Kindle model or Sony's PRS-500. However, not all authors have endorsed the concept of electronic publishing. J.K Rowling, author of the Harry Potter series, has stated that there will be no e-versions of her books.
Advantages
* Text can be searched automatically and cross-referenced using hyperlinks.
* A single e-book reader containing several books is easier to carry around (less weight and volume) than the same books (or sometimes even a single book) in printed form. Even hundreds or thousands of books may be stored on the same device. Using removable media even more can be carried around easily.
* Also at a fixed place such as at home it can be an advantage that an e-book collection requires very little space.
* Mobile availability of e-books may be provided for users with a mobile data connection, so that these e-books need not be carried around.
* E-books can allow non-permanent highlighting and annotation.
* Font size and font face can be adjusted.
* E-books may allow animated images or multimedia clips to be embedded.
* E-books allow for greater fidelity in colour reproduction compared to CMYK colour printing (although some e-book readers have only monochrome displays).
* Depending on the device an e-book may be readable in low light or even total darkness. For devices for which this applies, energy consumption for reading without daylight is less than that of a lamp needed for reading a printed book.
* An e-book can automatically open at the last read page.
* While an e-book reader costs much more than one book, the electronic texts are generally cheaper. Moreover, a great share of books are available for free, without any charge at all. For example, all fiction from before the year 1900 is in the public domain.
* Text-to-speech software can be used to convert e-books to audio books automatically.
* An e-book can be offered indefinitely, without ever going "out of print".
* Depending on possible digital rights management, it may be easy and cheap to produce a back-up for the case that the e-book is lost or damaged, and/or it may be possible to get a free new copy if that happens.
* It is easier for authors to self-publish e-books.
* A free e-book can stimulate the sales of the printed version.
* The production of e-books does not consume paper, ink, etc.
Disadvantages
* Reading e-books requires an electronic device and software. Even in the case of reading it on a personal computer one already has, it may require additional software.
* A small book is easier to carry around than a typical e-book reader.
* E-book readers require electrical power; in the case of mobile use, the battery can get exhausted.
* E-book readers are more fragile than paper books and more susceptible to physical damage.
* E-book readers can malfunction and e-books can be damaged due to faults in hardware or software.
* E-book readers are more likely to be stolen than paper books.
* Depending on the device an e-book may be difficult to read in bright sunlight.
* Most publishers don't produce the e-book equivalent of their printed books. In other cases the product quality is lower or it is released later.
* E-books can be easily hacked through the use of hardware or software modifications and widely disseminated on the Internet and/or other e-book readers, without approval from the author or publisher. This ease of piracy is a significant drawback for publishers.
* If an e-book device is stolen, lost, or broken beyond repair, all e-books stored on the device may be lost. This can be avoided by backup either on another device or by the e-book provider.
* There is a loss of tactility and aesthetics of book-bindings. Also lost is the ability to very quickly riffle through the pages to search for a particular section or to get a sense of the book merely by sight.
* Screen resolution of reading devices may be lower than actual paper.
* Due to the digital rights management reselling or lending out an e-book may have complications.
* Some books available as e-book cannot be read on some e-book readers because they are not supplied in a format those readers allow.
* While printed books remain readable for ages, changing technologies and less durable electronic storage media require e-books to be copied to a new carrier after some years.
* E-book readers require various substances to produce, and are an environmental hazard as they're non-biodegradable.
