Hi Chelsea, regardint the period after the DOI. APA explicitly mentions that there should be not period after the DOI, which makes perfectly sense to aviod confusion. I wonder why so many journals still place a period after the DOI. some journals even seem to have no consistent handling of this matter, so you can find publications wehere some references, ending with a DOI, are terminated with a period after the DOI while others (same paper) do not. This is a mess;-) Do you have an Idea why this is handled that sloppy by many journals? Best wishes Guido
