Chapter 2 — Vet and the CRAAP Checklist-Card

Vet, a small owl-tween, always wore her CRAAP checklist-card. It hung on a thin leather cord around her neck, a small, folded rectangle of sturdy paper. She had warm-brown and cream feathers, and her eyes were steady, thoughtful, like stones polished by a river. She was patient, quiet, and always attentive. The card was her signature feature, a hand-made tool with five sections: CURRENCY, RELEVANCE, AUTHORITY, ACCURACY, PURPOSE. Each section had a tiny space for notes.

This card wasn’t just a decoration. It was the key to how Vet saw the world. She believed in checking things, truly checking them, before you built any idea or argument on them. Not every piece of information is trustworthy. Not every source is right for every question. The CRAAP test is a set of five questions you ask about any source before you decide to use it. Librarians first developed this test as a teaching tool, making it concrete, memorable, and useful for any kind of information.

Vet was always clear about one thing: she never used source-evaluation to keep people out or make them feel silly. “CRAAP is not snobbery,” she would say, her voice calm. “It’s honesty about what kind of source this is, and whether it fits your research question. A blog post can be perfect evidence for some questions. A fancy, peer-reviewed article might be completely wrong for others. You have to match the source to the question.”

She taught the CRAAP steps carefully, holding up her card.

“First, CURRENCY,” she’d explain. “When was this published? Has it been updated recently? Is that date right for your question? If you’re researching the latest space missions, you need the newest information. But if you’re studying ancient Roman history, an older book might be exactly what you need.”

“Next, RELEVANCE. Does this source actually answer your research question? Or is it just sort of, well, around the topic? Is it deep enough for what you need, or too simple? If you’re trying to understand how a specific machine works, an article about the history of machines might be interesting, but it won’t give you the details you need.”

“Then, AUTHORITY. Who created this source? What are their qualifications? Are they an expert on this topic? Is it a scientist who spent years studying something, or just someone who likes the topic a lot and has a website? Knowing who is talking helps you understand their perspective.”

“After that, ACCURACY. Are the claims in this source supported by evidence? Do they list where they got their facts? Can you check those facts somewhere else to make sure they’re true? If a source makes a big claim, you want to see proof.”

“Finally, PURPOSE. Why was this source created in the first place? Was it to inform you, to persuade you to believe something, to sell you a product, or just to entertain? The purpose changes how the information is presented, and how you should read it.”

“All five questions, every single time,” Vet always insisted. “Don’t skip any. Use the card.” She knew different types of sources needed different weight on different questions. “Think about Wikipedia,” she might say. “Its Authority varies because anyone can edit it. But its Currency is usually good, and its Accuracy depends on how well it cites its sources. It’s a great starting point, but not usually your final source.” She saw this same careful thinking in SleuthLab’s investigation-bias register, where evidence-based reasoning always beat out hunches.

Vet grew up in a small village where her family had been the seal-bearers for generations. They were the owls who verified and applied the village seal to important documents, making them official. From a young age, Vet watched her parents work. They didn’t just stamp. They checked. Every line, every signature, every detail had to be exactly right before the heavy wax seal was pressed down. Trust, she learned, wasn’t given freely. It was earned through careful verification.

When Vet walked to ResearchQuest, a young owl of twenty-two, Scholar looked at her with keen eyes. “What is source-evaluation?” Scholar asked, a direct question. Vet didn’t hesitate. “CRAAP,” she said, holding up her card. “Five questions. Currency. Relevance. Authority. Accuracy. Purpose. Match the source to the question. All five, every time.” Scholar simply nodded. “You are appointed,” he said, and that was that.

“I have evaluated many sources,” Vet would often say. Her steady gaze swept over a room of young researchers. “Most new researchers skip the CRAAP step. They end up using information that doesn’t fit their question, or worse, isn’t quite true. Those five minutes spent CRAAP-ing a source can save you hours of wasted research.”

“It is not hard,” she’d remind them. “It is five questions, every time. CRAAP.”

The checklist-card waited, ready for the next source, ready for the next question.
