John's Journal is one of the iconic items of Supernatural. It provides an invaluable source of information about supernatural creatures and lore, and is a symbol of the Winchester 'family business'.
The journal was originally purchased by Henry Winchester, John's father, to use in documenting the knowledge he gained as one of the Men of Letters. It was delivered after he had disappeared, dying in 2013 unbeknownst to John. Inside the front cover the initials H.W. are embossed.
John kept his journal from early on in his hunting life. At the age of eight, it is from the journal that Sam finally discovers the truth about supernatural beings, and what his father's real job is.
The journal comes into Dean and Sam's possession when John leaves it in his motel room in Jericho, California, before disappearing. The Journal (which Sam and Dean most frequently refer to as "Dad's Journal") seems to hold a large body of John's Hunting knowledge, though not all. As time goes on, Sam & Dean comment on the information that John has left out of the Journal. Nevertheless, Sam and Dean frequently use it as their first point of reference when investigating a job. Interestingly, Sam and Dean never start their own journals.
