# Harry S. Bluston

I have previously expressed my interest in using Sinclair computers for more serious work and not just playing games. I’ve been collecting any Sinclair related books that are more into the scientific side.

While digging around the book archive of the “World of Spectrum” website, I found a couple of books that led me to the author, H. S. Bluston. In the early 1980’s he wrote some books for the ZX81 and Spectrum that looked interesting.
