What is Anne’s purpose in writing her diary?

Her Dad gave that diary to her for one of her birthday's and she often wrote in  it to express her hope as well as to document the experiences her, her family and friends had.

i would like to compare these two interpretations of the crucible : 1) eric christ's interretation and wade bradford's interpretation. the main differences between there interretaions is that in the first one you can notice direct link to joseph mccarthy whereas the second one represents how the town is filled with hysteria.the second interpretation shows that author believes that the story   about puritan town in salem is based on actual events while the first example shows the sencible reference to sort of bias.
