All it is is a 68000 with a 8-bit bus, but the instruction set seems to be the same, while the processor hides the 8-bit bus from the programmer by doing double 8-bit fetches in place of 16-bit fetches.... ....just in the same way as the 68000 pretends to be a 32-bit computer in spite of its 16-bit bus. Come to think of it, most 8-bit computers try to pretend half of the time that they are 16-bit anyway. But in this case, the 68008 is specifically designed as an 8-bit imposter for a 16-bit machine with full code compatibility. The book I have found really good for information on the differences on the 68000, -08, -10, -12, and -20 is one published by Osborne/McGraw Hill, called the "68k microprocessor handbook", SECOND edition, published 1986, but I bought my copy a couple of weeks ago at a bookstore in the backwoods (ie, Lexington KY). No one could sanely want to know more about the series than is in that book. So long, Alan Kennington.
