This letter should be short and will be addressed to the Contact Person in the Personnel or Recruitment Committee.

You should also include an extended abstract of your Thesis (about one page long) together with your job market paper. If you have other finished papers, you should also send copies of them. Here you can find some interesting suggestions on how writing a summary of your dissertation.
Applications usually ask for between 2 and 4 letters of recommendation from people you mention as reference in your CV or people best able to write a strong letter on your behalf. Make sure you ask for the letters early enough to the deadlines!
