Index Cards Eval: Digitized Catalog Metadata with Multimodal Extraction

Catalogue metadata extracted from digitised material with a multimodal model and human-reviewed. The dataset is authored by the NationalLibraryOfScotland and was last updated on July 16, 2026. It contains structured fields describing index cards, including headings, types, and cross-references.

Use Cases

• Train multimodal models for document classification based on the described image_type field.
• Evaluate entity linking and normalization for historical catalog entries based on the cross_reference field.
• Analyze the distribution of catalog entry types (person, family, corporate, geographic, subject) based on the heading_type field.
• Develop information extraction pipelines for digitized library card catalogs based on the described schema.

Strengths

• Metadata extraction involved human review, suggesting quality control.
• Schema includes specific, structured fields like heading_type and image_type for detailed categorization.

Limitations

• Row count, file formats, and column-level documentation are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
