The Slayer Handbook was a manual given to Slayers by their Watchers to instruct them on how to operate as the Slayer. One of these handbooks, titled Vampyr on a large leather bound tome was owned by Rupert Giles. The book was extraordinarily old; Dracula claimed this book was "the first attempt by man to record and codify the laws of magic." Giles presented it to Buffy Summers when she first arrived in Sunnydale. After meeting Buffy, Giles decided she wasn't one to follow rules and put the book away. It was presumably kept at his apartment in Sunnydale.
After his death, Giles left the book to Buffy. Though Faith was left with all the rest of Giles's possessions, she believed that Giles was trying to tell Buffy that she was the one true Slayer and he believed in her. It was last seen in the weapons chest in Buffy's bedroom in San Francisco.
After they teamed up, the Slayer Handbook was sought after by Severin and Simone. They believed it would help them successfully turn Simone into a vampire instead of a zompire, after which she would be able to defeat Buffy. Among its contents was the secrets of the Deeper Wellspring and how to access it.
After the new Seed of Wonder was formed, Buffy and Willow discovered, much to their shock, that the Slayer Handbook was now completely blank. Days later, some of the pages of the book had become filled again, but now described entirely new laws of magic. Newly written pages kept appearing as new laws of magic were being established, but it turned out the reverse was also true: writing new laws into the book would cause these laws to become true. However, it's possibly to have rules rejected with the ink squirting back into the scribe's face. Xander claims this is because the book doesn't like retcons or clichés.
