Our payments from copyright licence fees are calculated using data sourced from sample surveys and other sources. We use the best data available to us, at a reasonable cost, about the copying and sharing of content under each of our licences.

We broadly categorise data for distribution as:

1. transactional licence data (information about a licence for a single work)
2. full records (information about each use under a ‘blanket’ licence)
3. survey data (information about usage by samples of licensees): 
4. indicative data (information from other sources about content available to a licensee class)

Sources of indicative data currently used include:

• supply of digital press clippings
• library holdings provided by the TAFE sector
• library holdings and lendings collated and provided by the National Library
• sales data from Nielsen BookScan
• information from rightsholders about their published works, available for copying by licensees.
