While ebooks have been around for many years, recent rapid improvements in the versatility and affordability of e-readers and tablets, along with increased access to broadband internet, have lead to a dramatic rise in household ownership of these devices. Between 2012 and 2013, the proportion of children responding to the National Literacy Trust's annual literacy survey who owned an e-reader rose from 20% to 30%, while tablet ownership increased from 38% to 65% and smartphone ownership from 38% to 70%. A 2013 Ofcom survey found that tablet use at home by children aged 5 to 15 almost tripled between 2012 and 2013, rising from 14% to 42%,. Electronic publishing has also developed during this time, allowing readers access to an ever-growing range and quality of ebooks, whenever and wherever they happen to have their portable device to hand. Academic and media interest in the difference between reading in print and reading on screen has grown as devices and software facilitating reading on screen become a greater part of everyday life, leading to a growing field of observation exploring the relationship between children's reading on screen and their reading skills and behaviour. While, until recently, the quality and quantity of ebooks for children has not been sufficient to provide material for large-scale longitudinal studies, many aspects of reading on screen have been explored in a range of international and national research. This rapid review draws together findings from studies related to children's screen reading behaviour, enjoyment and skills, both from secondary sources and in (as yet unpublished) findings from the National Literacy Trust's annual literacy survey 2012, which included questions examining the interplay between children's use of technology and their reading habits. National Literacy Trust survey sample characteristics are appended.
