+# Dataset Card for `cord19`
+
+The `cord19` dataset, provided by the [ir-datasets](https://ir-datasets.com/) package.
+For more information about the dataset, see the [documentation](https://ir-datasets.com/cord19#cord19).
+
+# Data
+
+This dataset provides:
+ - `docs` (documents, i.e., the corpus); count=192,509
+
+
+This dataset is used by: [`cord19_trec-covid`](https://huggingface.co/datasets/irds/cord19_trec-covid), [`cord19_trec-covid_round5`](https://huggingface.co/datasets/irds/cord19_trec-covid_round5)
+
+
+## Usage
+
+```python
+from datasets import load_dataset
+
+docs = load_dataset('irds/cord19', 'docs')
+for record in docs:
+    record # {'doc_id': ..., 'title': ..., 'doi': ..., 'date': ..., 'abstract': ...}
+
+```
+
+Note that calling `load_dataset` will download the dataset (or provide access instructions when it's not public) and make a copy of the
+data in 🤗 Dataset format.
+
