Hiya! What (and how specific)should I write in an "motivation letter", what not? Is one page sufficient?

This link may help you.

Thank you very much Ann! In the meantime I have found very interesting sites.... on web.

more than sufficient! if it is more than one page it wont be a mottivation letter....it will be a boring letter!Be short and precise i think that is the most important! It is always nice to reffer to the work the lab is doing in the present!
