+# Datasets Index
+
+This dataset is a curated collection of scientific datasets from across the web, compiled to support open-source machine learning in science. Many of these datasets are difficult to access, scattered across domain-specific websites, or stored in inconvenient formats. The goal of this index is to make them more discoverable for researchers, engineers, and contributors to the HuggingFace4Science community.
+
+# Dataset Overview
+
+Rows: 52 datasets/urls
+
+Format: CSV file
+
+Fields:
+
+id – Unique identifier
+
+created_at – Timestamp of entry creation
+
+dataset_name – Human-readable dataset name
+
+dataset_url – Source link
+
+description – Short summary of dataset contents
+
+approx_size – Estimated dataset size
+
+size_unit – Unit of size (e.g., MB, GB, TB)
+
+field – Scientific domain (e.g., physics, materials science, biology)
+
+user – Contributor who submitted the dataset
+
+# Use Cases
+
+Discovery: Find datasets relevant to ML in physics, chemistry, materials science, and beyond.
+
+Preprocessing: Many listed datasets are in raw formats (NetCDF, FITS, domain-specific archives). This CSV provides a starting point for building standardized loaders.
+
+Community Contribution: Expand the list by submitting new entries, cleaning existing datasets, or publishing derived versions to Hugging Face Datasets Hub.
+
+# How to Contribute
+
+- Suggest new datasets via the Hugging Science community.
+
+- Contribute loaders, enrichment scripts, or preprocessed dataset cards.
+
+- Help validate metadata (sizes, formats, licenses).
+
+# Disclaimer
+
+This index does not host the actual datasets. It only provides links and metadata.
+Users are responsible for checking each dataset’s original license, distribution restrictions, and usage terms before downloading or using the data.
