Do you have the Dictionary of Occupational Titles?
We do have that title as an eBook from 2004. The link to the catalog record is below. From there, you will see a link that says eBook, click here to access to get into the book.
If you are off campus, you will have to log on with your last name and COM ID. If you don't have a COM ID, then you'll have to come to the library to access it.
If you want more current info from the Dept. of Labor, who produces this title, you can search their website directly. The link is below. The site tells what education is required, typical working conditions, salary outlooks, etc.
I've included a couple other useful links, both national and state.
