Non-fictionPublishing is a weird industry, a retail supply service where every day hundreds – thousands – of brand-new, untested products are launched, each one a little bit different to the last. The long-haul career trajectory of most writers is increasingly difficult to maintain with incomes nosediving, as evidenced by multiple surveys. The road is cluttered with novelists brought down by ‘bad track’, their new books rejected because of the poor sales of previous titles. But as readers we still need help to discover good books, to figure out what to read next. As book pages, magazines and newspapers shrink or disappear altogether, it’s no longer clear what impact book reviewers can have on a career. The endorsement of someone whose work – critical or otherwise – you admire remains important to many writers.
