An odd, self-serving mix--part New York handbook, part explanation of recent state initiatives, part future campaign manifesto--from New York's governor (Diaries of Mario M. Cuomo, 1984). Cuomo may be much lauded for his rhetoric, but here occasional rhapsodies are subsumed in the bureaucratic discussion of what he calls ``the New York Idea: government using its resources to help create private sector growth,'' then requiring some of those who benefit to share with those less fortunate. Hardly original to New York. Cuomo goes on to skate lightly over such New York issues as immigration, multiculturalism, state lending programs, transportation, scientific research, and public higher education (he at once praises ``democratic access'' and plays down the impact of rising tuition at the state university). Section headings like ``Agriculture--One of Our Oldest and Most Valued Industries'' convey a cheerleading tone. As might be expected, Cuomo sometimes claims too much credit (such as for the Nehemiah project for low- cost housing in New York), but he sometimes plays down some of his administration's efforts, such as his massive prison construction program. His final section, expressing hope for the future, is followed by appendices with saccharine descriptions of New York regions (Long Island is ``alive with exciting attractions and activity'') and long lists of highlights and innovations from his reign. Perhaps Cuomo's future campaign committee will buy and distribute this book; it has little other purpose.
