January 2019 Sources: 02/02/19
January I primarily focused on my own books, ones purchased in 2018. Secondarily was research. Finally there were some due library books. As it's a new year, there were some newly published books too.
Despite there being four newly published books, all but one were for research, thus keeping my ROOB score good.
January 2019 is right in the middle for all Januarys, though it is the lowest one in recent years.
My average for January dropped slightly from -2.37 to -2.39
