The authors run Career Blazers, Inc. and have more than 10 years' experience in lining up first jobs for new college graduates. Little hometown kids with those bigtown dreams would benefit from the briskly written hard facts, for the book deals with the sought after, so-called ""glamor"" careers to be had in advertising, TV, public relations et al, which are mostly metropolitan centered. The cautionary advice deals with the grubby starts these fields provide for the richly educated, under-experienced liberal arts graduate with no specific, certified skill. The message is: Girls! Take heart and take typing -- the young ladies get off to a start from clerk-stenography. Boys! The way to the executive suite starts in the mailroom. Beginning salaries that seem designed for slow starvation are charted by occupation. Helpful hints on the organized approach to job-hunting, letters of application and what resumes are made of are gone into at briefly informative length. It's all quite true and as shaking as a cold shower bath in a cap and gown. The optimism comes from the thought that starting so low, there is no place to go but up.
