Book editors do much more than checking grammar and spelling and if necessary asking writers to cut out pages of text.
They're also painstaking fact checkers.
On Standing Room Only last year Lynn Freeman interviewed Andi Buchanan about their novella From A Shadow Grave that's set in several different time periods.
Andi talked about their editors picking up on the fact that teabags and types of makeup they'd assumed were around in the 1930's, actually weren't.
Lynn tracked down the two editors who were students on the Whitirea Publishing course in Wellington last year...Christine Cessford and Gem MacDuff.
