Microcopy - The Complete Guide

The book covers very specific situations that are usually forgotten on most copywriting literature, like how to solve empty states on web forms. In that sense is simply great. It helps the writer to take good decisions on little details that you probably oversaw or took for granted when you started writing. Every chapter is documented with lots of real cases, and the arguments to support the advice are almost unquestionable. So you just have to "follow the instructions", so you spare a lot of critical writing time and efforts.
