Not too much Dandy in books

Presumably like a lot of researchers, I have been spending time browsing the vast collection of materials on Google Book Search. You can learn about it here.
However, instead of searching the millions of scanned pages for "economic theory," "common themes in Elizabethan comedy" or "home brewing ales" like the rest of the researchers, I have been searching for topics such as "Sheffield Wednesday," "Seijun Suzuki" and "UK reggae music."
It was in pursuit of information in the latter category that I recently searched for "Dandy Livingstone."
From the hundreds of thousands of volumes on display, my search resulted in a mere five books. Only five books contained any mention of Dandy Livingstone!
Is this apparent oversight a big deal?
One of the five books, "Writing Black Britain, 1948-1998: An Interdisciplinary Anthology," explains why it might seem an unfair lack of published information.
The book describes Livingstone as "the first British reggae star to gain national recognition."
So, why so few references in books?
Born Robert Thompson in Jamaica, Livingstone moved to the UK when he was 15 and by the early 1970s was creating a much-admired body of work:
* The Specials paid homage, covering his classic "Rudy, A Message to You."
* The Bodysnatchers covered his "Let's Do Rock Steady."
* UB40 covered his elegant take on the deejay phenomenon, "Version Girl" (Livingstone released it under the guise of Boy Friday).
Apart from well-respected songs given new life by others, Livingstone also scored a pair of Top-30 singles in the UK:
* "Suzanne Beware of the Devil" reached No. 14 in September 1972.
* "Big City" reached No. 26 in January 1973.
So, if Livingstone was so well-respected and successful, with enduring songs that left a lasting impression on succeeding generations of British musicians, why are there so few books about him?
Maybe I should take a year's sabbatical in London, research his life and career, and write my own book about Dandy Livingstone!
