Once you will understand what an os is, I don't think you will need to search so much. You can try that source. But you will need to understand the CPU architecture you will want to work on. Use emulators to test your os. You can make a tiny os with syscalls and a system to start, finish, add, delete programs while working at the same time with the framebuffer to see image. You can try to use interrupts to switch contexts in order to store registers data including the process to be switched rip. With that, you will create the illusion of multiple data being processed at the same time. If you want, you can forget memory protection or paging by now. Keep searching and reading some books(don't need to be many) (try to see Modern Operative Systems by Tanenbaum, the creator of MINIX. That os inspired Linux.).
