We started the research by looking at news articles, which included Forbes, the Guardian and Publishersweekly, since these are likely to provide statistics on the yearly number of self-help books published. However, only a list of top self-help books and a guide on how to select those to purchase was available. Our next strategy was to look at reports and journals related to self-help book publications. We looked for this information on the websites for Book Publishing Report and International Publishers Association, but only information on the state of the publishing industry was available. We then expanded our search by looking at databases and market research reports of published books including Market Research, Statista, Worldometer and IBIS World. We found information on the CAGR and market size of the global publishing market. On Worldometer, we did find information on the books published so far in 2019.
We then searched the International Standard Book Number website to check if there is a section with self-help books so we could use the assigned book numbers to determine the number of self-help books published in 2018. Unfortunately, this attempt failed. We also checked catalogs where book lovers and buyers review and purchase books. These catalogs include Goodreads, Amazon and Barnes & Noble. However, we only found the details of popular books (including those of the self-help books) on these platforms.
We then decided to triangulate the number of self-help books published in 2018 by using the number of new books published in 2019. A back calculation was done using the CAGR growth of published books to get the number for 2018. We then calculated the percentage of global book publishing revenue that belongs to self-help books. This was then used to determine the number of self-help books published in 2018. The detail of the calculation is below:
Number of new books published in 2019= 2,022,530 (this is the value when the website was accessed)
Estimate for the whole year i.e 52 weeks (through extrapolation) = Number of new books published in 2019 x Number of weeks in a year/Number of weeks spent in the year= 2,022,530 x 52/40 = 2,629,289
Calculation on the number of books published in 2018
The estimated number of books published in 2018= Number of new books published in 2019 - (CAGR x Number of new books published in 2019)
CAGR of published books= 1%
The calculated number of new books published in 2019= 2,629,289
Therefore, the estimated number of books published in 2018= 2,629,289 - (1% x 2,629,289) = 2,602,996.
Percentage of book publishing market made up of the self-help books
Percentage of global books publishing made up of self-help books= Self-help books revenue/global book publishing revenue x 100.
Global book publishing revenue in 2018= $112 billion
Self-help books revenue in 2018= $800 million
Therefore, the percentage of global books publishing made up of self-help books= $800 million/$112 billion x 100= 0.71%
Number of self-help books published in 2018
Number of self-help books= percentage of global books publishing made up of self-help books x estimated number of books published in 2018 = 0.71% x 2,602,996= 18,481 books
