Cover Letters

Hi,
I have read through a lot of postings here about how to fix up and format resumes and cv's, but I have not seen much about cover letters. Is there any sort of "formula" or way you go about cover letters? Please share ideas on what you think they should be about, how long they should be, etc.

When applying to an online posting through an application system (whether it's Monster, CareerBuilder, Taleo, or that organization's system), if they do not recommend or give an opportunity for a cover letter, then it is not recommended to make one. When applying via email, you should always send one (it can be the body of the email) unless it is specified that you do not need one. If it is specified to send a cover letter, you should absolute send one every time. Some organizations will not consider you without one, and it may greatly improve your chances.
Cover letters are not as IT-specific as resumes, so formats you will find online from Google (you'll probably find a lot on About.com) will be suitable for IT work as well.
