Answer 2

Perhaps you are unable to comprehend the size of the World Wide Web. If you did, if you understood how many web sites exist, you would understand that it is improbable there will EVER be a web site that lists all web sites and what they contain.

Here's a little excercise in mathematics for you, to help you understand what I'm saying. I'm going to be talking about powers:
think of the number 1. singular.
now you see the dot that comes after the one?
Now imagine there is an infinite number of zeros after the dot, and before the one, like this:
0000001.00000 recurring forever.
A power is when that dot is moved.
so, 1 times 10 to the power of 1 is equal to 1 times 10, which equals 10. 1 times 10 to the power of 2 is equal to 100. 1 times 10 to the power of 3 is equal to 1000.
2 times 10 to the power of 3 is equal to 2000.

according to Wikipedia, "According to a 2001 study[7], there were more than 550 million documents on the Web, mostly in the "invisible Web". A 2002 survey of 2,024 million Web pages[8] determined that by far the most Web content was in English: 56.4%; next were pages in German (7.7%), French (5.6%) and Japanese (4.9%). A more recent study which used web searches in 75 different languages to sample the Web determined that there were over 11.5 billion web pages in the publicly indexable Web as of January 2005.[9]

sourced from: http://en.wikipedia.org/wiki/World_Wide_Web#Statistics

11.5 billion pages equals 115 times 10 the the power of 7

now here's the volume of information that includes what is not accessible to the public.
A recent study still ongoing by a task force assembled by the united nations to combat communication between terrorist cells in different countries revealed that the total number of pages on the web is increasing by several thousand per day, and is roughly 1 times 10 to the power of 1000 (only round numbers could be used, because it is merely a calculated estimate). Thats 1000 zeros with a 1 at the beginning. Didn't I tell you it is more pages than can be imagined.

Answer 3

If you do a Yahoo or Google search that will list most of the sites which relate to the search criteria

Answer 4

check 'Directories' in any major search engines
