There is no cost for basic access
to the corpora from
English-Corpora.org. But you might want to
have a "premium account", which you can purchase by clicking on one of the links
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. 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.
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...)
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 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.
