2. e-book
An e-Book (short
form of electronic
book) is an e-text
that forms the
digital media
equivalent of a
conventional
printed book.

3. • An electronic book (variously: e-book, eBook, e-
Book, ebook, digital book, or even e-edition) is a
book-length publication in digital form,
consisting of text, images, or both, readable on
computers or other electronic devices. Although
sometimes defined as "an electronic version of a
printed book",many e-books exist without any
printed equivalent.

4. • Commercially produced and sold e-books are
usually intended to be read on dedicated e-book
readers, however, almost any sophisticated
electronic device that features a controllable
viewing screen, including computers, tablet
computers, and smartphones can also be used to
read e-books.

5. E-book reading is increasing in the US,
since by 2014 28% of adults had read an e-
book, compared to 23% in 2013. This is
increasing because 50% of Americans by 2014
had a dedicated device, either an e-reader or a
tablet, compared to 30% owning a device at the
end of 2013.

6. Michael S. Hart (1971)
Despite the extensive earlier history, several
publications report Michael S. Hart as the
inventor of the e-book. In 1971, the operators
of the Xerox Sigma V mainframe at the
University of Illinois gave Hart extensive
computer-time. Seeking a worthy use of this
resource, he created his first electronic document
by typing the United States Declaration of
Independence into a computer.

7. e-reader :
An e-reader, also called an e-book reader or e-book
device, is a mobile electronic device that is designed
primarily for the purpose of reading e-books and
digital periodicals. An e-book reader is similar in
form, but oftentimes more limited in purpose than, a
tablet. In comparison to tablets, many E-readers are
better than tablets for reading because e-readers are
more portable, have better readability in sunlight (if
they are e-ink readers), and may have longer battery
life.

8. E-reader applications:
Additionally, some of the major book retailers and
multiple third-party developers offer free (and in some
third-party cases, premium paid) e-reader applications
for the Mac and PC computers as well as for
Android, Blackberry, iPad, iPhone, Windows Phone
and Palm OS devices to allow the reading of e-books
and other documents independently of dedicated e-
book devices. Examples are apps for the Amazon
Kindle, Barnes & Noble Nook, Kobo eReader, and
Sony Reader.

10. e-Books are usually read on
personal computers or smart phones or
dedicated hardware devices known as
e-Book readers or e-Book devices.
Many mobile phones can also used to
read e-Books.

11. Comparison of e-Book with Printed Books
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.

12.  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.

13. 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 privacy is a significant drawback
for publishers.

14. 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.

15. 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 sense of the
book merely by sight.

16. 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.

17. 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
hazards as they are non-biodegradable.

18. • Physical discomfort for some users, including
eye strain.
• More expensive, whereas used books are cheaper
and most often only a few hundred rupees can
be lost or stolen at one time.
• A book will never break, but an e-book device
can break, and a lot of money can be lost at one
time.

19. • One will never read thousands of books really
well or over a short period of time, so the high
amount held on an e-book reader becomes
irrelevant.
• A book is safe from electromagnetic pulses and
overloads.
• A whole paper book is never broken beyond
repair, unless entirely burnt or decayed.

21. PRODUCTION OF E-BOOKS
Some e-books are produced simultaneously with
the production of a printed format, as described in
electronic publishing, though in many instances they
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.

22. Scanning a book produces a set
of image files, which may be
additionally be converted into text
format by an OCR programme.
Occasionally, as in some e-text
projects, a book may be produced by re-
entering the text from a keyboard.
