I'm so old that the last time I wrote a research paper, it was on a word processor with no Internet connection or spell check.

Given such constraints, I can't fathom the concept of waiting until the end to add all the references. If I didn't do it as I went, I'd have surely died.

I should add that we always read each other's papers before submission to get a second set of eyes for errors, misspellings, and grammatical quagmires. It was mutually beneficial as the reviewing made us all better. Is that still a common practice?

I mean, depends on whether you think someone will actually check what the references actually say or just eyeball the titles and go LGTM.

That’s the same as writing tests for software code after writing the code. A mystery without end or reliability.
