Each entry starts with the person's first name. Then the year and street name and then the address on the street. The next column is marked if the address was a home address and the following column is marked if it is a work address. A few people had both addresses listed each year. The last column is the occupation listed for that person.
The occupation is very useful for tracing people with similar names. People generally stayed in the same industry or trade. They might have different jobs within the industry but most remained in that work group.
That knowledge has not always been very helpful to me. My great-grandfather Robert W. Smiley was a beamer and lived in Frankford. There was another Robert W. Smiley who was also a beamer who lived in Germantown. I have since found that he was a nephew.
Let me know if you find anthing useful here.
