The resume is the first step, your introduction to an employer. First impressions really do count. If you make a poor first impression, you'll never get to step two -- the job interview. To the purpose of your resume is to make a good first impression. In effect, your resume should tell the employer that you have good abilities and are truly interested in working. This report will help you make that good first impression. And it could very well help you to get the better job you're looking for.
As has been indicated above, the word resume comes from the French word resume meaning "summary". Leonardo da Vinci is credited with the first resume though his "resume" takes the form of a letter written about 1481–1482 to a potential employer, Ludovico Sforza. For the next roughly 450 years, the resume continued to be a mere description of a person, and included their abilities and past employment. In the early 1900s, resumes listed things like weight, height, marital status, and religion. It was not until 1950 that the resume evolved into something more than words written on scraps of paper. By then, resumes were considered very much mandatory, and started to include things like personal interests and hobbies. It was not until the 1970s, the beginning of the digital age, that resumes took on a more professional look in terms of presentation and content.
Make sure there are no misspelled words! Mistakes will create the wrong image. Make sure that the punctuation is correct. And make sure that all of your columns line up. See that all of your facts are correct. Don't say you attended 3 years of college, but only show two years worth of grades. Potential employers will note all inaccuracies and wonder why they appear in your resume.
Your salary requirements should not be listed in the resume, if you can avoid it. The reason is that if you put too low of a salary, you might be paid less than the real value of the job. If you put down a figure that's too high, you may not get considered for the job. If an employer likes you, it may be possible to negotiate a higher salary during the interview stage. Another thing that your resume doesn't need is your photograph. Potential employers can decide if they are interested in you after reading your resume. They can see what you look like during the interview.
