+# HF Datasets Master Index
+
+A comprehensive rolled-together dataset of **4,810 unique datasets** found across **227 HuggingFace profiles** (90 people + 137 orgs).
+
+## What's Inside
+
+This dataset consolidates all publicly available dataset references from:
+1. **Profile dataset pages** - datasets published by each profile
+2. **Profile collections** - datasets bookmarked in collections
+3. **Model cards** - datasets referenced in model training descriptions
+4. **Model tree traversal** - datasets inherited from base models through finetunes/merges/quants
+5. **Your personal collections** - mc7ever's 52 HF collections
+
+## Columns
+
+| Column | Description |
+|--------|-------------|
+| `dataset` | HuggingFace dataset ID (org/name) |
+| `profiles_using_it` | Pipe-delimited list of profiles that use/reference this dataset |
+| `num_profiles` | Number of profiles using it |
+| `collections_it_appears_in` | Collections where this dataset appears |
+| `your_collection` | Your personal collection name (if applicable) |
+| `direct_model_references` | Number of models directly trained on this dataset |
+| `ancestral_model_references` | Number of models that inherit this dataset through base model tree |

+## Usage
+
+```python
+import pandas as pd
+
+df = pd.read_parquet("hf_datasets_master.parquet")
+
+# Most-used datasets
+df.nlargest(10, 'num_profiles')[['dataset', 'num_profiles', 'total_model_tree_refs']]
+
+# Datasets in your collections
+df[df['your_collection'] != '']
+
+# Datasets with most model references
+df.nlargest(10, 'total_model_tree_refs')[['dataset', 'total_model_tree_refs']]
+```
