corpus contains more than billion words of
text from online magazines and newspapers in 20
different English-speaking countries from 2010 to the
current time (see sources). If you're interested in what's going on
in English up to and including right now, this is by far
the best corpus available.
When you purchase the
full-text data from NOW, you get all of the data up
through the month of purchase. You can also purchase an annual subscription, which will
give you another year's worth of data (typically about
1.7 billion words each year).
For example, if you
purchase both datasets on 15 July 2019, you would have
the data from Jan 2010 - June 2019 (which was released on
July 2; see the samples in #2 below), and an annual subscription would give
you the data for one more year: July 2019 - June 2020.
If you purchase just #1
above, it would be the price of
one corpus, and there would be a
discount for purchasing both
corpora (#1 and #2) at the same time.
Note also that the monthly updates will be
released at the beginning of the following month (at the
latest). You will be notified
as soon as the update is available, and you will have
ten days to download the data.
