Karin,
General Studies student
"My chosen assignment was to find information on
the growth of the population in the Lismore area during
the 20th century. I found a local history book in the
library (a secondary source), and that
had some information, but that wasn't enough. The local
council had some statistical tables (a primary
source), which gave a lot more detail.
My teacher asked the class to list primary and secondary
sources separately when listing our sources".
