# Bibliography Coverage **LIBRARY-FIRST RULE: ALWAYS check Paperpile (`paperpile search-library`) when assessing coverage.** Compare a project's `.bib` file against a Paperpile project/topic folder to identify gaps between the project bibliography and the reference library. ## When to Use - After a literature search, to see what % of the topic collection is cited - Before submitting a paper, to catch references you forgot to cite - When reviewing a Paperpile project/topic folder, to find items not yet in any project's `.bib` - After a bibliography-quality check, as a complementary completeness check ## When NOT to Use - **Finding new references** — use an installed literature-discovery workflow or scholarly search - **Validating .bib quality** (missing fields, DOI issues, preprint staleness) — use an installed bibliography validator - **Building a .bib from scratch** — use `bib-parse` or an installed literature workflow ## Inputs 1. **Project `.bib` file** — detected automatically (same logic as `bib-validate`: look for `references.bib`, then any `.bib` in the project) 2. **Paperpile folder** — resolved from: - Explicit `--topic <slug>` argument - Project's `CLAUDE.md` or Atlas topic frontmatter - Directory name if inside a research project - If no collection can be resolved, report an error and suggest specifying `--topic` ## Workflow ### 1. Load Project Bibliography Parse the `.bib` file to extract all entry keys and titles. ### 2. Load Paperpile Fol...
