In December's Digest Deborah Poff, COPE Chair, reflects on the past year and plans for the future. We list the top 5 cases visited on our website in 2019 which deal with issues of plagiarism, authorship, predatory publishing and ethical oversight, and we have four new cases to share with you as discussed by #C0PEMembers at the latest forum. Members at the forum began a discussion on 'Artificial Intelligence in decision making' which we summarise and invite you to add your comments. Join us in determining the next steps for our fictional research integrity officer, Jo, who we introduced in March this year. Plus the monthly news roundup and events coming up in 2020.
