Many thanks for all the suggestions as to how to describe my new publication on the 1922 Committee. The entries were on a par with a caption competition (but without the prize!). I rather liked the suggestions of describing it as a treatise or a monograph. Both would apply, but they would not solve the problem in that using either would not create a discrete category of publication: a number of my books are treatises and monographs. A booklet would create a distinct category, but may not quite do justice to it in terms of length. I did think of creating a category of ‘short monographs’. I think I may go with that. I would thus have separate sections for books, short monographs, pamphlets, book chapters, articles etc. Then again, I think Jana and D F Rostron may have a point. I could treat it as a short book – it has an ISBN – and include it as a book. I will wait until it is published and then decide (if it looks like a book, feels like a book…). Watch this space.
