Another great post from Bobby Owsinski –

I’m not sure how this directly applies to music but it sure is fascinating. We think of the Web as everything that Google can find, but did you know that there’s a huge amount of data that’s not indexed or searchable?

It’s estimated that the size of the searchable Web is 167 terabytes (a terabyte is 1024 gigabytes) while the so-called “Invisible Web” or “Deep Web” is 91,000 terabytes!! Wow, that’s a lot of data that can’t be easily found.

Why isn’t this data available via Google? Google sends out spiders to regularly index websites, but there are some that require a password that just won’t allow that kind of access. These include private networks and library sties, which have huge amounts of information.

There are a number of ways to access the data of the “invisible web” though, and here are 10 search engines that are expert in just such a task, thanks to a great article on MakeUseOf. I’ll give you a brief overview here, but see the entire article for more detail.
