You help keep the corpora financially viable. There are now more than 130,000 unique users of the corpora each month, and it takes a lot of money and effort to make them available. The income from premium accounts helps maintain the corpora. We also need to be planning for changes that will take place in the near future, so that the corpora can stay online. (more...)

You help those less fortunate. Without the income from premium accounts, we'd probably need to move to a paid license for everyone, like some other corpus sites. Unfortunately, this would probably exclude some lower-income students or teachers at universities in developing countries. The income from your purchase of a premium account helps provide access for those who cannot afford one.

Note that your university can also purchase an academic license, which allows multiple users from your university to have all of the advantages shown above.
