Bookshelf One of Many

Some of the books on this shelf sum up my main passions - theatre (especially musicals) and walking (especially Cumbria). There are even a couple of titles in there that combine the two - The Blue Box - The Story of the Century Theatre 1947-1983 and Encore! - Ten Years of Theatre By The Lake.

This shelf is representative of the books in these two categories. Elsewhere in the house are shelves laden with musical scores, sheet music, librettos and scripts; maps and atlases and of course a set of Wainwright's Pictorial Guides (although these 'officially' belong to Husband of Mine).
