Our friend Google indexes billions of websites spread all over the planet. However, some information cannot be accessed from Google or popular search engines because it is found on the deep web. Databases containing often confidential information should be searched directly on specific sites. Some people do not want to be identified when sharing information with everyone, or they do not want certain authorities to have access to this information. It only takes a little curiosity to learn to browse the deep web (or the "invisible" web).
Steps
Part 1 of 2: search for hidden information

Step 1. Search for databases
You can search for "hidden" databases or "hip-hop" databases with traditional search engines. However, it will be practically impossible for you to find the information you are looking for, because it is not indexed by the search engines (there are no links and the "bots" of the search engines have not indexed it).. So you usually have to write the direct URL, but sometimes the search engines will direct you to the home page of the site which you can crawl using the internal search bar.
Some free deep web sites are particularly interesting, for example the National Library of France or the libraries of the University of Pau

Step 2. Do a specific search
If you don't have a specific address, you can use some search engines to search the deep web. The majority of these search engines are in English like Infomine or the superb WolframAlpha, but there are some search engines accessible in French of excellent quality like BASE, WorldWideScience, Secouchermoinsbête or DADI.

Step 3. Go to the libraries
Libraries, more particularly those attached to universities or grandes écoles, pay to have access to databases with specific information that are not accessible from common search engines. Some university search engines are accessible online, such as that of the University of Paris Sud, but you can access the search engines by connecting to the Internet from a computer in a bookstore. The site Many offers a search engine by categories.

Step 4. Browse the archives
Some information and sometimes videos or digital files have gone missing because the site that hosted them is closed or the information has been deleted. You can find some of this information, videos or music files (and even copies of early video games) on The Internet Archive Project, which collects and aggregates a wide variety of digital files for safekeeping. for posterity.
Part 2 of 2: Use TOR

Step 1. Use TOR

Using this network is bordering on legality (it actually depends on how you use it), but TOR is used by many journalists to preserve the anonymity of their sources as well as individuals. wishing to browse the web in a confidential manner.
Access to the Deep Web or the Invisible Web is perfectly legal. The activities to which you devote yourself may, on the other hand, be less so

You may sometimes have to wait hours or days before you can connect to certain websites.
- You can use TOR with an Android system or from an iPad or iPhone. This is not recommended, however, as there are compatibility issues, especially with applications. The TOR browser offered on the Apple App Store would also be a malicious program.

Step 3. Protect Your Identity

Step 5. Use a specific search engine

Some sites are more specifically dedicated to the underground world of the Web, this is the case with this website and this collection of digital books.

Step 7. Communicate with users
The deep world of the Web is in constant motion. This is due on the one hand to the lack of budget of the people building the sites and having to ensure their maintenance and monitoring, it is also because of the many illegal activities that take place there. Some sites are closing and there are constant changes in the corridors of the Invisible Web. You can keep up to date with the movements of the Deep Web by talking with other users on OnionChat.
