About

What this is

A browsable reference to the whole of mathematics as organized by the MSC2020 Mathematics Subject Classification — the scheme used by Mathematical Reviews and zbMATH to classify research literature. The goal is to give learners, researchers, and the curious a structured way to go from a broad branch of mathematics down to a specific, named subfield, with an overview, key ideas, and real references at each stop.

How it's built

This is a fully static site — every page is pre-generated from structured data, with no backend or database involved. That keeps it fast, cheap to host, and simple to archive.

Content standards

• References are academic papers, not books — each one individually verified against a real source rather than generated by keyword-matching alone. A companion Google Scholar search link helps find a downloadable copy of each.
• Recommended textbooks are kept separate from references, each with a link to buy or borrow it.
• The Open Textbooks and Gutenberg Library pages link out to genuinely public-domain or openly-licensed books, organized by topic — nothing is re-hosted or copied.
