When world building, do you often use non-fiction sources? If so, what types of sources do you turn to?
Miles Lacey said:In my work in progress the technology etc is the 1920s and 1930s so there is a lot of information about it.
One of the most useful things I have is a 1934 German encyclopedia that is useful because it shows how things worked and it has illustrations of contemporary things like buses, motorcycles etc.
