Each profession is superficially surveyed in double-page spreads containing a brief paragraph of flat prose and a color photograph often lacking sharpness. Terms such as [cf2]first aid, cement,[cf1] and [cf2]responsibility[cf1] are defined in footnotes, rather than being incorporated into the text. Each book concludes with a project. Bib., glos., ind.
