We talked about the famous directories like Librarian's Internet Index ( LII) and Internet Public Library ( IPL), but we never mentioned DMOZ, the Open Directory Project with 4,616,309 websites organized in 590,000 categories by 83,367 editors.
From the beginning, the directory data has been offered free of charge to site owners who would like to use it to enhance their own site.
If this is your first time here, welcome! It's worth pointing out that our volunteer editors select sites for inclusion in the directory based on unique content, so a stroll through the directory can provide an excellent overview of a particular topic.
DMOZ serves as a base for Google Directory, other websites are also allowed to use the data on their pages.
Since DMOZ is quite extensive to browse, that is why I always use the advanced search features and limit my search by category or site.
