System calls, by definition, are part of the operating system. If the source code for your operatnig system is available, you can download and browse it. Similarly for the C library, you can download the source for e.g. GNU glibc.

For more tutorial expositions, in addition to Lions, there's the BSD devil books (different books for 4.3BSD and 4.4BSD) and a book by Plauger about the standard C library. Quick googling also brought up The Linux Kernel: The Book
