⭐⭐⭐ out of 5
This is a must-have for every children's writer or illustrator, but most of this years book seems to cover other countries and stuff. For such a huge volume there are only maybe 50 pages of agents and publishers in the UK which is OK if you are looking for contacts around the rest of the world and by the time it was published most of the information was out of date.
In previous years I'd got a lot more UK agents and publishers on my spreadsheet, but only about 10 entries *combined* out of this one. It's good that they cover the world's agents and publishers, but it seems to be at the expense of the UK unfortunately.
I've never got this every year (last year I bought this was the 2016 yearbook in 2015) and have always valued it covering every agent and publisher of children's books in the UK but seemingly not any more.
If you've never bought the yearbook before, or you want to find worldwide agents and publishers then this yearbook will hopefully help you, but if you've bought it in the last few years, save your money on this one because more things have been taken out of the UK part than put in!
