Nielsen BookScan has been a data provider for the book publishing industry, owned by the Nielsen Company up to 2016, though it is still in use via the NPD Group. BookScan compiles point of sale data for book sales.
Following the success of Nielsen SoundScan which tracked point of sale figures for music, the Nielsen Company decided to launch a similar service for book sales. Nielsen BookScan was launched in January 2001. Previously, tracking of book sales, such as by the New York Times Best Seller list, was done without raw numbers. The New York Times would survey hundreds of outlets to estimate which books were selling the most copies, and would publish rankings but not figures. Only the publisher of a book tracked how many copies had been sold, but rarely shared this data.
Nielsen BookScan relies on point of sale data from a number of major book sellers. In 2009 Nielsen BookScan's US Consumer Market Panel covered 75% of retail sales.
Use of BookScan
BookScan was initially greeted with skepticism, but is now widely used by both the publishing industry and the media. Publishers use the numbers to track the success of their rivals. The media uses the figures as a reference to gauge a title's success. Daniel Gross of Slate has noted the increase of pundits using the figures to disparage each other.
BookScan also provided previously unavailable metrics on books published by multiple publishers, such as classic novels in the public domain which may be published by many different houses. Previously, no single entity had figures for the sales of these books; publishers and bookstores only knew their own sales. Slate noted that Jane Austen's Pride and Prejudice was available from Amazon in 130 different editions; prior to BookScan there was no way to tabulate total sales. By summing BookScan data, however, Pride and Prejudice was reported to command sales of 110,000 a year, nearly 200 years after being published.
BookScan records cash register sales of books by tracking ISBNs when a clerk scans the barcode. BookScan only tracks print book sales, thus excluding ebook sales from major e-tailers such as Amazon Kindle, Barnes & Noble Nook, Kobo, Apple, and Google Play. BookScan likewise does not include non-retail sales through channels such as libraries, nor specialty retailers who do not report to the service.
BookScan and other services, as Pubtrack Digital, PubTrack Higher Education, PubTrack Christian, Books & Consumers, PubEasy und PubNet belong to The NPD Group since January, 2017. NPD has acquired these services from Nielsen’s U.S. market information and research services for the book industry. These services will be part of NPD Book, a new U.S. practice area.
Nielsen will offer these services furthermore in 9 countries outside U.S., named "Nielsen Book".
