As well as the existing index headers, he has provided an index of Book Reviews, of the Gazetteer of Flying Sites, and of people, and he has even provided a full serial search for aircraft photos – which is really useful!

While this work has made it much easier to search the index, it has revealed a few flaws. Sometimes there are multiple entries for the same term – for example the famous VC Captain W Leefe Robinson is variously reported as Leefe-Robinson, Robinson, WL and Robinson! We need your help to improve the index, so please feel free to report back to us any errors, duplicates or inconsistencies you come across.
