Next library

The family grows. Every future ElkassabgiData library plugs into the same account system on day one — if you're registered, you already have access.

Works inside Claude & other AI assistants

Every library is also available through the ElkassabgiData MCP server — connect https://elkassabgidata-mcp.elkassabgi.workers.dev/mcp in Claude or any MCP client and your assistant can search, fetch, and analyze the data with citations attached. Setup guide →

One account. Every library. Forever.

Register once — on this page, on hfdatalibrary.com, or on econdatalibrary.com — and you are an ElkassabgiData registered user: the same free API key downloads data from every current and future library. No re-registration, ever.
