DMOZ

DMOZ (Open Directory Project) is an open directory with various types of entries created by editors from all over the world. The entries are in various languages. A major advantage of DMOZ is that anyone can access the directory and the submission of new entries is completely free. It is also worth noting that all data is continuously checked and monitored through the use of automatic mechanisms that remove outdated entries. Each search engine analyses the data contained in the DMOZ.
