The authors can be sorted into four groups, according to the age group they write for: children aged 5-7, 8-11, 12-14 and 14+. Where an author writes for more than one age group, this is shown. These age groups are intended as a guide and should not be viewed as prescriptive. Our aim is to encourage children and young people to read as widely as possible, so we ask users of Who Next...? to bear in mind the preferences, abilities and needs of individual children.

The 14+ age group is not as comprehensive as the others but is an attempt to highlight other titles that are often overlooked. Some of the stories involve difficult and often controversial material such as eating disorders, suicide and fatal illness and, therefore, should be recommended with sensitivity. Adults’ authors that may be suitable for this age group can be found at www.whoelsewriteslike.com.
