I was wondering if anyone has any information about falsification of history and the annulment of the past in 1984 by Orwell.

In 1984, the main character Winston
Smith, plays an employee of the government whose job is to partially annul the past. He
receives strips of paper, scraps of paper, documents and pamphlets that are his job to
destroy. He is able to read them or look at them, but the telescreens prevent him from
recording them or noting anything interesting about them. He seems fully and completely
aware of what he is doing as the story is told from a perspective that sees his
thoughts. Winston knows that this is wrong morally, but legally according to the laws of
this land he does the right thing and destroys the documents that would lead people to
believe anything other than what "Big Brother" wants them to
think.

The way you phrase your question makes it unclear as
to exactly what you are looking for, but 1984 is certainly a
storyline that suggests a reconstructing of history which is indeed falsification. The
Party destroys any document that would make them sound bad and presents information,
even if it is not true, to people that makes the government sound good. Consider the
connotation that goes along with "Big Brother". Instead of saying "Mean Dictator" they
make this unknown leadership seem warm and
inviting.

Consider re-writing your question to elicit the
specific response you are looking for.
