There is no cost for basic access to the BYU corpora. But you might want to have a "premium account", which you can purchase by clicking on one of the two links below.

Month Year      Amount    (can be more than minimum, if desired)
$8.00 $25.00      $    

Some of the advantages of a premium license are the following:

1. More streamlined searches. You won't be bothered with the messages that appear every 10-15 queries, asking you if you want a premium license.

2. You can have increased access to the corpora.
Those who have premium accounts can have higher daily limits on the number of queries. "Non-researchers" can increase from 50 to 200 queries a day, and researchers can move from 200 to 400 queries each day.

3. 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 help 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...)

4. 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 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 that.

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