This is one of the books I recommend to my coworkers who are interested in operating systems - it teaches a surprising amount of things by telling you what an OS will do for you and therefore why you need it, instead of telling you how it works inside.

It also remains being very pleasant to read in spite of its very large size( I read the whole book cover to cover ). Obviously you can also read the classics ( minix book, tanenbaum, Bach , and probably modern references ) but this one somehow gives the operating system a purpose which I find absent in the others I’ve read .
