FYSOS: The Virtual File System (FYSOS: Operating System Design Book 2)

Can't believe this author isn't more well-known. There's a huge lack of practical low-level software development literature out there, and this guy has an entire series on developing an OS from scratch. Worth your time if you want to improve as an industrial programmer.

This book and the series that it is from are ideal to teach yourself some intricate subjects surrounding OS development. This author has taken several important steps to include relevant information and key ideas involving hard to find subjects and common things involved in OS development.I hope this series continues to expand sometime in the near future.Excellent value too!
