I've started using Mendeley and noticed that the automatically generated references don't always standardize - for example sometimes a doi would show up, but sometimes not. I try checking the info to make sure that all that's needed is in there when I import documents.
Due to this I've started typing in citations by hand. But I would still like to use the handy citation so it doesn't interrupt my flow. Has anyone had this problem? Is there something else I should do?
