Getting citations right
How to check a citation is real, why AI invents references, what to do when a source turns out fake, and how to cite in APA, MLA, and Chicago.
A citation does two jobs. It points a reader to the exact work behind your claim, and it shows you actually read that work. Both jobs break in the same place: the reference looks right, and the source either does not say what you claimed or does not exist at all.
That failure got much more common once students started drafting with chatbots. A language model predicts what a plausible reference looks like, so it produces real-sounding authors, a real journal, a sensible year, and a DOI with valid syntax that resolves to nothing. Published studies put the fabrication rate anywhere from a few percent to more than half, depending on the model and how it was asked.
The fix is boring and it works. Check every reference before you submit, and cite as you write instead of bolting references on at the end. Checking one source takes about a minute: open the DOI, confirm the title and authors match, and read enough of the paper to confirm it supports your sentence.
These guides cover the whole chain, from why models invent references to what to do when a professor says your sources do not exist, and how to format a citation once you know it is real.

All topicsChatbots invent references that look real, down to the DOI. Why it happens, the fabrication rates measured in every published study from 2023 to 2026, and how to keep fake sources out of your work.
Six checks with free tools that verify any reference in about five minutes, how to tell a fabricated citation from a garbled one, and what to do when one turns out fake.
What actually cuts fabricated references in ChatGPT: turning on search, supplying your own sources, better prompts, and the one limit no prompt can fix.
The current APA, MLA, and Chicago formats for citing an AI tool, with a correct in-text and reference example for each, plus the bigger point: cite the real study, not the chatbot.
Most plagiarism isn't theft, it's drift: a paraphrase that stayed too close, a note you forgot was a quote. The habit that prevents it, and how to handle AI text honestly.
The source exists, the DOI resolves, and it still doesn't support your sentence. Why this failure is more common than fabrication, and how to catch it.
