"After all, the electronic versions of about a third of retracted papers aren’t marked as retracted. Sometimes, like Napoleon, those papers return from exile to wreak havoc: They get cited as if they had never been retracted." Retraction Watch, Adam Marcus 12/13/2012
"As a reader once commented to us, 'there is no statute of limitation on retractions.' " -- Fang, F.C. & Casadevall, A. (2011). Retracted science and the retraction index. Infection And Immunity, 79(10), 3855-3859 https://iai.asm.org/content/79/10/3855.full
When writing your paper or article, always make every effort to check each of your citations to ensure the work you are citing is not a retracted work. If you rely on a resource that has been previously retracted, it can negatively impact your own work and reputation.
