An e-book (short for electronic book, also written eBook) is the digital media equivalent of a conventional printed book. Such documents are usually read on personal computers, or on dedicated hardware devices known as e-book readers or e-book devices. An eBook is an electronic version of a traditional print book that can be read by using a personal computer or by using an eBook reader. (An eBook reader can be a software application for use on a computer, such as Microsoft's free Reader application, or a book-sized computer that is used solely as a reading device, such as Nuvomedia's Rocket eBook.) Users can purchase an eBook on diskette or CD, but the most popular method of getting an eBook is to purchase a downloadable file of the eBook (or other reading material) from a Web site (such as Barnes and Noble) to be read from the user's computer or reading device. Many mobile phones can also be used to read eBooks. Generally, an eBook can be downloaded in five minutes or less.
Although it is not necessary to use a reader application or device in order to read an Ebook (most books can be read as PDF files), they are popular because they enable options similar to those of a paper book - readers can bookmark pages, make notes, highlight passages, and save selected text. In addition to these familiar possibilities, eBook readers also include built-in dictionaries, and alterable font sizes and styles. Typically, an eBook reader hand-held device weighs from about twenty-two ounces to three or four pounds and can store from four thousand to over half a million pages of text and graphics. A popular feature is its back-lit screen (which makes reading in the dark possible).
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 2008, new marketing models for e-books are being developed, formats are beginning to homogenize, and dedicated reading hardware has been produced. E-books have achieved global distribution, and electronics manufacturers are releasing more e-book readers for general consumer use, such as Amazon's Kindle model or Sony's PRS-500. E-books have seen tremendous market growth in
Advantages
- Text can be searched automatically and cross-referenced using hyperlinks, making the e-book format ideal for works that benefit from such functions.
- E-books can allow non-permanent highlighting of books.
- Less physical space is required to store e-books, and hundreds or thousands of books may be stored on the same device.
- A single e-book reader containing several books is easier to carry around than several print books.
- Because they require little space, e-books can be offered indefinitely, with no going out of print date, allowing authors to continue to earn royalties indefinitely.
- Readers who have difficulty reading printed books can benefit from the adjustment of text size and font face.
- Text-to-speech software can be used to convert e-books to audio books automatically.
- E-book devices allow reading in low light or even total darkness by means of a back light.
- An e-book may be more comfortable for some to hold because it need not be held open like a physical book and can also be set down and read without needing to be held open.
- An e-book can automatically open at the last read page.
- It costs little to reproduce or copy an e-book, which makes it ideal for archival and backup purposes.
- While an e-book reader costs more than one book, the electronic texts are generally cheaper.
- It is easier for authors to self-publish e-books.
- Ease of distributing e-texts means that they can be used to stimulate higher sales of printed copies of books.
- Although they require electricity to be read, the production of e-books does not consume the paper, ink, and other resources that are used to produce print books.
- 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).
Disadvantages
- If not viewed on computers, e-books require the purchase of an electronic device and/or peripheral software which can display them. If they are to be viewed on a personal computer, it may require additional software
- Not all publishers produce the e-book equivalent of their print books. In other cases, e-books are given a lower priority in terms of the publisher's resources, resulting in a disparity in product quality, release dates and the like. This problem is not endemic to every publisher, but has an effect on the quality of the overall pool of merchandise available.
- All e-book devices require electrical power, resulting in the consumption of electricity.
- Looking at a screen for a long time may cause eye trouble and sometimes headaches.[citation needed]
- Certain e-book formats may become obsolete and incompatible with future devices.
- E-book readers are more likely to be stolen than paper books.
- E-book readers are more fragile than paper books and more susceptible to physical damage.
- As an e-book is dependent on equipment to be read, it can be affected by faults in external hardware or software, such as hard disk drive failure.
- E-books can be 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.
- 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.
- Screen resolution of reading devices may be lower than actual paper, making it difficult to read e-books.
Equality
With the pervasiveness of the Internet, both e-books and print books can now be purchased from electronic stores such as Amazon.com and do not require going to a bookstore.
Production
Some e-books are produced simultaneously with the production of a printed format, as described in electronic publishing, though in many instances they may not be put on sale until later. Often, e-books are produced from pre-existing hard-copy books, generally by document scanning, sometimes with the use of robotic book scanners, having the technology to quickly scan books without damaging the original print edition. Scanning a book produces an image file, which must then be converted into text format by an OCR program.[5] Occasionally, as in some e-text projects, a book may be produced by re-entering the text from a keyboard.
As a newer development, sometimes only the electronic version of a book is produced by the publisher. Usually, it is possible to convert electronic book to a printed book by print on demand.
E-book publishing as an industry is growing in the double digits yearly, according to the quarterly reports put out by IDPF. Among the first Internet-only publishers of new e-books were Boson Books, Hard Shell Word Factory and Online Originals, all founded in the mid-1990s. Each pioneered different aspects of what has since become common practice amongst e-book publishers, e.g. the support of multiple formats including PDFs, the payment of much higher royalty rates than conventional publishers, and the online presentation of free samples. Hard Shell Word Factory set the first professional standards for commercial e-books and pioneered author-friendly contracts. Online Originals was the first e-book publisher to win mainstream book reviews (in The Times) and a nomination for a major literary prize (the Booker Prize).
Since the late 1990s, the many newcomers to e-book publishing have included most major print publishers. At the same time, many established e-publishers started to offer print versions of some of their titles. Thus the line between the two is fast blurring.
There are some parts of the industry where there are particularly notable leading firms. In the general field of science-fiction and fantasy, Baen Books, an American publishing company established in 1983 by science fiction publishing industry long-timer Jim Baen (1943-2006) has a well-established position. It is a science fiction and fantasy publishing house that specializes in space opera/military science fiction and fantasy (though it does not restrict itself to these subgenres). It is notable for releasing books without DRM in a variety of formats, before hard-copy publication, and pre-releasing ebooks in parts before the hard-copy release. Many older titles are available for free, especially the first book in a series.
