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 below.

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

Messages			Messages every 10-15 searches, asking if you want a license	No more messages; uninterrupted searching
Searches (click for explanation)			Basic access (per day)	With premium license
		# searches	20	200
The number of searches for strings (e.g. *ism, fast NOUN, VERB to VERB) or collocates that you can do each day.
		# KWIC lines	2000	20,000
The number of Keyword in Context (KWIC) / concordance lines (the word in context) that you can view each day.
		Word pages (COCA / iWeb)	20	200
The number of "word pages" that you can view each day ("main" word page, topics, collocates, clusters, KWIC, etc).
		Browsing (COCA / iWeb)	150	1,000
The number of distinct words that you case see each day as you're browsing through the word list.
		Analyze texts (COCA)	10 searches / 250 words each	100 searches / 5,000 words each
The number of times that you can submit a text to be analyzed (by word and phrase) each day, and the maximum length of each text
Saved lists			# lists	(Explanation)
The following features are primarily reserved for those who have a premium account (for individuals), or through an academic license (from your university). But even those without a license can create a few lists -- kind of like a "taste test", to see how they work.
		Virtual corpora	5 (per corpus)	1,000
Maximum number of Virtual Corpora that you have created for a given corpus (e.g. COCA or NOW)
		Saved KWIC lines	5 lists / 100 lines (per corpus)	1,000 lists: 20,000 lines
# of concordance lines (words in context) that you have saved.
		Saved words / phrases	5	1,000
Number of words and phrases that you have saved.
		Customized word lists	5	1,000
Number of customized word lists that you have created.
		Search history	20 searches	10,000 searches
Number of entries shown from your search history

In addition, with a premium license:

You help keep the corpora financially viable. The corpora are now accessed by more than 75,000 registered 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.

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.
