Input: Consider Input: I was enchanted with this fascinating book on barn conversions. Barns are great relics from our past, conveying a sense of history, but many have been ruined by weather, time, and neglect. I didn't realize how many creative architects and owners have made barns useful for both residential and commercial use through renovation and restoration. The intrinsic character of these old barns brings an integrity and charm rarely seen in new construction. In many gorgeous illustrations, Rooney describes the history of barns, their adornment (who knew that it was all because of a 9th century pope that there are so many roosters on weathervanes?), and their use as gorgeous residences and fascinating commercial and establishments - including an architectural office, inns, and even a funeral chapel. One entrepreneur even used several to develop an office complex. If you love barns and if you like to see the past preserved in the present, you will love this book.

Output: Positive

Input: Consider Input: After all these reviews, it is difficult to not feel like I would be doing an injustice ... yet, I think that those who claim to like Lhasa would much prefer the originality and talent of Chavela Vargas. Indeed, Lhasa's raspy voice is deeply influenced by the cigarrette-smoking Vargas. What is called haunting voice, or passion, by other reviewers, is a mode of interpretation that Lhasa administers indiscriminately to every song in her repertoire, especially when the CD includes merry Chrismas songs.
