A little history:
A Wander-Buch is a work record for a journeyman. A journeyman must first complete an apprenticeship as they went from Master to Master to learn their trade. It was a record the journeyman
could use along with letters of recommendation or accomplishment from those various masters to earn their own master in their trade.

The Wanderbuch is usually a work record for a journeyman craftsman, but in this case Johann Jacob seems to have used it mainly a personal diary.

Another use of the word Wanderbuch was used in the Catholic Kolping Society. It was mostly called a Gesellenwanderbuch but it also documented the travels of members of the workers society as they
travelled from place to place while staying at local Kolping houses in the various cities they traveled through. It served as an admission card from one place to the next.
