<Title>What is Lorem Ipsum?</Title>
<Paragraph>
Lorem Ipsum is simply dummy text of the printing and typesetting
industry. Lorem Ipsum has been the industry&apos;s standard dummy text
ever since the 1500s, when an unknown printer took a galley of type and
scrambled it to make a type specimen book. It has survived not only five
centuries, but also the leap into electronic typesetting, remaining
essentially unchanged. It was popularised in the 1960s with the release
of Letraset sheets containing Lorem Ipsum passages, and more recently
with desktop publishing software like Aldus PageMaker including versions
of Lorem Ipsum.
</Paragraph>
<Title>Where does it come from?</Title>
<Paragraph>
Contrary to popular belief, Lorem Ipsum is not simply random text. It
has roots in a piece of classical Latin literature from 45 BC, making it
over 2000 years old. Richard McClintock, a Latin professor at
Hampden-Sydney College in Virginia, looked up one of the more obscure
Latin words, consectetur, from a Lorem Ipsum passage, and going through
the cites of the word in classical literature, discovered the
undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33
of &quot;de Finibus Bonorum et Malorum&quot; (The Extremes of Good and
Evil) by Cicero, written in 45 BC. This book is a treatise on the theory
of ethics, very popular during the Renaissance. The first line of Lorem
Ipsum, &quot;Lorem ipsum dolor sit amet..&quot;, comes from a line in
section 1.10.32.
</Paragraph>
<Paragraph>
The standard chunk of Lorem Ipsum used since the 1500s is reproduced
below for those interested. Sections 1.10.32 and 1.10.33 from &quot;de
Finibus Bonorum et Malorum&quot; by Cicero are also reproduced in their
exact original form, accompanied by English versions from the 1914
translation by H. Rackham.
</Paragraph>
<Title>Why do we use it?</Title>
<Paragraph>
It is a long established fact that a reader will be distracted by the
readable content of a page when looking at its layout. The point of
using Lorem Ipsum is that it has a more-or-less normal distribution of
letters, as opposed to using &quot;Content here, content here&quot;,
making it look like readable English. Many desktop publishing packages
and web page editors now use Lorem Ipsum as their default model text,
and a search for &quot;lorem ipsum&quot; will uncover many web sites
still in their infancy. Various versions have evolved over the years,
sometimes by accident, sometimes on purpose (injected humour and the
like).
</Paragraph>
<Title>Where can I get some?</Title>
<Paragraph>
There are many variations of passages of Lorem Ipsum available, but the
majority have suffered alteration in some form, by injected humour, or
randomised words which don&apos;t look even slightly believable. If you
are going to use a passage of Lorem Ipsum, you need to be sure there
isn&apos;t anything embarrassing hidden in the middle of text. All the
Lorem Ipsum generators on the Internet tend to repeat predefined chunks
as necessary, making this the first true generator on the Internet. It
uses a dictionary of over 200 Latin words, combined with a handful of
model sentence structures, to generate Lorem Ipsum which looks
reasonable. The generated Lorem Ipsum is therefore always free from
repetition, injected humour, or non-characteristic words etc.
