I tell people all the time that they should keep a journal, even if it's just, 'I had a terrible day today and I don't want to talk about it, love Stevie,' or 'I dreamt last night...' Even if it's just three sentences because at the end of five or six days, you would have created a habit and you will find that over a month that you have a whole story growing. Whether it's just for your own memories, so you can go back at any age, or if you are a writer or a singer, or some part of the creative business. You can be creative ~ anyone can be creative if they want to ~ you just have to want to.
Stevie Nicks, Musicians in Tune by Jenny Boyd, 1992
Seconds–
The breeze that sends the blinds softly rippling and the short breath, sudden spritz of the air freshener
–At the same time, on their own time.
The Time Traveler's Bible is just the regular Bible, but read by a time traveler, which by the very nature of time travel changes the history of an object. While this is true of any book, the peculiarities of the Bible make it particularly useful for time travelers to consult for guidance. The Bible is omnipresent in a real sense--it is everywhere, in most major households, in libraries, institutions, and of course... hotel rooms. This always-there nature means that time travelers can almost always depend on it, and thus have almost always depended on it.
Every time traveler changes a book in a different way, but for books that are touched by many time travelers, the changes all compile together, becoming a sort of master codex of time travel. A time traveler will read not the Bible's passages but the changes in them, note the subtle differences in the text that existed in various other time travelers' worlds before any of them touched it, and note the changes that one's own self introduces to the canon. This produces a mental map of many human-traveled temporal variants.
The limitations of this method are largely in the limitations of the book utilized. The Bible is, of course, dominant in its own web of realities, and thus it is unwise to grow dependent on its structure. Other branches of timespace require other books, some require anchors that aren't books, and to access many, many more requires possession of a thing even more daunting for the well-read to acquire:
A lack of literacy.
Not every reality is one that humans learn to read in. There, you will find not just a lack of Bibles, but the utter absence of any books and the knowledge to make, read or write them.
