What does we shall in Tail mean?? I dont understand the word "Tail" thank you

Busy weekend Today I went to department stores with my mum and cousin. We bought many stuffs. I enjoyed it but in my head, there was only word "essay". I have hand in the essay to my teach next thursday!. I think this essay will be the most difficult essay that I have ever done. Because I have to write it within 2,500 - 3,000 words and have to references more than 10 journal articles. The topic is quality service. It seems to be easy essay but in fact, it is not. How long time that you usually finish your 2,500 words essay? Now I am trying to search good journal articles which are related to quality service. Does anyone know good websites that I can find good one and free? Thank you :)
