Primary school libraries are a vital part of the education system. A well-resourced primary school library not only supports literacy levels but has a positive effect on the mental wellbeing of pupils. Despite their numerous benefits, there is currently no statutory requirement for primary schools to have a library and even before the COVID-19 pandemic, primary school libraries were operating under pressure. This report draws together evidence from across the sector and submissions from teachers to give an idea of the current situation in primary school libraries; the benefits they bring to pupils and the challenges that they are facing. If the link between libraries, books and outcomes is as strong as the evidence in this report leads readers to believe, then there must be support for primary schools so that all pupils can benefit. The author calls on the government, public, private and charitable sectors to take on board the recommendations made in this report and bring in measures to support primary school libraries across the country.
