OpenAlex Articles + Harvard Library Item Data

Dataset Description

This repository contains two large tabular subsets built from Harvard Library Bibliographic Metadata and an OpenAlex snapshot.

These files are derived, filtered, and processed datasets, not full reproductions of the original source data. The records are based on real source metadata, but the dataset was prepared mainly for library data system operations testing, large-scale experimentation, and workflow development.

The main subset is best understood as a bibliographic/title-level table enriched for testing. In other words, a single row represents a bibliographic record or work-level description, while the copy_count field shows how many Harvard-linked copies/items are associated with that record. So one title can correspond to multiple physical copies.

The harvard_library_item_location subset is a more item-level / copy-level table derived from Harvard source data, intended to show the physical location associated with individual library items.

Source Data

This dataset is derived from:

• Harvard Library Bibliographic Metadata
• OpenAlex snapshot

Please refer to the original source projects for authoritative documentation, provenance, and update practices.

Subsets

1. openalex_articles_with_harvard_library.parquet

Large bibliographic-level dataset combining OpenAlex-style descriptive metadata with Harvard-derived library testing fields.

Columns

• id — record identifier
• title — title of the work
• author — author name(s)
• language — language code
• publication_year — publication year
• publisher — Harvard: publisher / OpenAlex: source name
• isbn — ISBN,Harvard: when available | OpenAlex: ALL MISSING (NOT BOOK type)
• doi — DOI, OpenAlex: when available
• copy_count — Harvard: number of linked copies/items | OpenAlex:ALL MISSING
• type — Harvard: BOOK, DVD, VIDEO, etc | OpenAlex: ALL "journal article"
• is_physical — Harvard: whether the item is physical (true) | OpenAlex: ALL(false)

2. harvard_library_item_location.parquet

Item-level Harvard-derived location dataset showing where individual physical items are stored.

Columns

• record_id — record identifier key to merge back to openalex_articles_with_harvard_library.parquet
• barcode — unique identifier for the item/copy
• library_branch — library or branch code associated with the item
• location — location code within that branch, such as a shelving, storage, or service location
• item_type — BOOK, DVD, VIDEO, etc

Intended Use

This dataset is intended for:

• testing library data pipelines
• large-scale query and indexing experiments
• metadata transformation and enrichment workflows
• prototyping discovery, retrieval, and analytics systems

This dataset is not intended to serve as a complete or authoritative replacement for the original Harvard Library or OpenAlex source distributions.

Notes

• This repository contains processed subsets, not the complete upstream datasets.
• Coverage, field normalization, and record selection reflect project-specific filtering and transformation steps.
• Null or missing values may appear in fields such as isbn, doi, or publisher.
• The source metadata is real, but this packaged form is optimized for testing and experimentation rather than archival completeness.
