The 100th title in the Poyser series (see our review of The Common Buzzard on p. 183) is a notable milestone in ornithological publishing. The Poysers, with their distinctive white dust jackets, are one of the most iconic series of natural history books ever published in Britain (and, with a few exceptions, they are specifically bird books, many of them being monographs). The name reflects the two founders of the series, Trevor and Anna Dorothy Poyser, sadly no longer with us, but the imprint continues under the custodianship of Bloomsbury. Jeremy Greenwood’s obituary of Trevor Poyser (see Brit. Birds 111: 292–294) provides a good summary of the series. The first Poyser I ever saw was Bird Observatories (which I borrowed from my local library and copied out the chapter on Gibraltar Point longhand) and the first one I bought was the first Breeding Atlas, now nicely yellowed with age and slightly tatty. As I’d never had ambitions to collect the whole series, it was a surprise to discover that there are over 80 Poysers on the shelves in my office; and I bet many BB readers have a similar collection and can remember their first too. According to our reviewer, Ian Carter, the 100th volume is a good one. How appropriate that it deals with a species that has increased so dramatically over the publishing lifetime of the Poyser series.
