There is no cost for basic access to the corpora from English-Corpora.org. But there are several benefits of having an academic license for your university (or other organization), including the following:

1. Classes and academic departments can have more than 250 searches (combined) each day
2. Users will not see the messages that appear every 10-15 searches (to suggest upgrading to a paid license)
3. Individual users will have more searches each day -- 400 for faculty, 200 for students (compared to the normal 200 and 50)
(See full list from individual user, "premium license" page)
