# M2D2: A Massively Multi-domain Language Modeling Dataset

*From the paper "[M2D2: A Massively Multi-domain Language Modeling Dataset](https://arxiv.org/abs/2210.07370)", (Reid et al., EMNLP 2022)*

Load the dataset as follows:
```python
import datasets

dataset = datasets.load_dataset("machelreid/m2d2", "cs.CL") # replace cs.CL with the domain of your choice

print(dataset['train'][0]['text'])
```
