Galileo has holdings from 1792-1993, which can be accessed at this link, http://www.augusta.edu/library/resources/galgruconnect.php?link=augt-reg1.
Reese library also has 1993-2013 issues on microfilm, as well as 2014 in print copy. You may also be able to search the Augusta Chronicle website through their archives.
Please let me know if I can be of any more assistance.
Sincerely,
