Does A Corpus Of Archaic English Words Exist?

I have a large database/wordlist containing probably every English dictionary word plus many additional ones like brand names, but this naturally includes many words no longer in use. I need to cut down the size of the list, but since too many words have been added to it to start from scratch, my plan is to obtain a corpus of only archaic words and use these as negatives to remove from the main wordlist. Does such a corpus/wordlist exist anywhere in text form, even it’s just a word per line? Thank you in advance, any help is much appreciated.
