astrobib

A terminal-based literature manager for astrophysics research

astrobib connects to the NASA/Harvard ADS to search, fetch, and organize papers as plain BibTeX files, with a fast terminal UI. It ships as a single native binary: instant startup, instant quit, no runtime dependencies.

Your library is just a directory of .bib files, indistinguishable from hand-written BibTeX, and cite keys derive from each paper's stable identity (arXiv ID or bibcode) — so any two copies of a paper, fetched by anyone at any time, agree on the key forever. Libraries from all earlier astrobib versions work unchanged.

Installation

uv tool install astrobib     # or: pipx install astrobib

Binary wheels cover macOS (arm64, x86_64) and Linux (x86_64, aarch64). Building from source needs a Rust toolchain: cargo install --git https://github.com/clemson-cal/astrobib.

Quick start

# set your ADS token (https://ui.adsabs.harvard.edu/user/settings/token)
export ADS_API_TOKEN=...

astrobib                     # launch the TUI
astrobib list                # CLI: newest papers
astrobib search '^zrake OR kw:"compact objects"'
astrobib add 2020ApJ...123..456Z
astrobib import refs.bib     # resolve a foreign .bib against ADS

The two-tier library model

astrobib always works on up to two libraries: a local bib directory (tier 2) and your global personal library (tier 1, at ~/.local/share/astrobib/library/). astrobib [LIBRARY_DIR] points tier 2 at any directory holding bib/; with no argument, the nearest ancestor of the current directory with a bib/ is used. A .tex or .md manuscript alongside activates citation tracking, but any bib directory works. With the global tier enabled (the default), reads merge both tiers and imports write to both — the paper repo stands alone for coauthors while your collection accrues. Press t (or click the global badge) to hide the global tier: reads and writes become purely local. Removing a local paper never destroys a sole copy — it is rescued into the global library. Both stores are plain bib/*.bib files, one paper per file, indistinguishable from hand-written BibTeX. Nothing else is ever written into your repos.

TUI overview

Scope capsules at the top switch between your library, saved ADS query tabs, and the manuscript view. A one-cell colour strip at the left edge shows the active metric — your own decaying priority, or ADS citation counts. The pub card on the right shows the highlighted paper (hover the citekey column to preview others); an event log and clickable view badges sit at the bottom. Most things are clickable; every action has a key (? shows the cheat-sheet).

Keys

• / — live filter (query language below); S — new ADS query (↑/↓ sets result count; pasting a DOI or ADS URL imports directly)
• j k g G — move; [ ] — switch scope; ctrl+w — close query scope; r — refresh; + - — result count
• Space — select row (iOS-style selection mode); a — select visible; A — select all; Esc — done
• i — import ADS result(s); m — toggle manuscript/local membership; ⌫ — remove (with confirmation)
• p — download PDFs (ADS open-access, then arXiv); B — browser download (watches ~/Downloads); o — open PDF; X — clear PDF; double-click a row — open its PDF
• y — copy chord: yy cite key, yY full key, yb bibcode, ya/yx/yd ADS/arXiv/DOI URL, yp PDF path, yt title, yA abstract; card title/abstract/key are click-to-copy
• C / R — open a citations / references query for the shown paper; v — pub view (the raw .bib); e — export the selection to a .bib file
• M — metric swatch column (priority, citations; distinct colormaps); . — priority 1.0, 0 — clear, < > — scale it (decays weekly); the wheel over a swatch does the same for that row
• t — show/hide the global tier; D — pub card; L — event log; ? — keys; @ — about; q — quit

Filtering the library

Press / to filter as you type. Whitespace-separated terms AND together; each term is a case-insensitive partial match. Bare terms match author, title, abstract, key, keywords, and year; field prefixes narrow:

author:sironi          author anywhere in the list
^zrake                 first-author papers (= author:^zrake)
title:magnetar         word in title
abs:"fast radio burst" phrase in abstract
kw:"compact objects"   keyword
year:2015-2020         ranges; year:2020- open-ended
is:ms                  local/manuscript members;  is:pdf  cached PDFs
pri:>0.5  cit:>100    metric comparisons (> < or bare for ≥); no metric never matches
-abs:neutrino          leading - negates (NOT works too)
^zrake OR ^metzger     uppercase OR separates alternatives; AND binds tighter

A half-typed query never errors. With a filter active, S pre-fills the equivalent ADS query — filter locally, escalate in one keystroke.

ADS queries

S passes your query to the ADS API unmodified, so the full Solr language works (bibstem:ApJL, citations(...), boolean grouping, …). Each query becomes a scope capsule, persisted per library context in tabs.json. The pub card walks the citation graph directly: click "cited by N" (or the citations/references affordances) to open a citations(...) or references(...) scope for the shown paper.

Markdown manuscripts

Literature reviews and notes work as manuscripts too: any .md files beside bib/ are scanned for citations (main.md is the sole root when present; Obsidian ![[embeds]] pull in more files, like \input). Cite pandoc-style — bare @Zrake2019 or bracketed [@Zrake2019; @Metzger2017] — or with Obsidian wikilinks: [[Zrake2019]] counts as a citation when it resolves in the library, and stays an ordinary note link when it doesn't. An unresolved @cite shows as missing in the Manuscript view, same as LaTeX. astrobib refs renders the bibliography of everything cited into the manuscript — a sorted, linked reference list (authors, year, italic title, journal, ADS/arXiv/DOI links) kept between <!-- astrobib:references --> markers, appended as a ## References section the first time. Regenerate any time; your prose is never touched.

refs.bib and co-authors

For TeX manuscripts, refs.bib regenerates silently whenever the TUI rescans — and the TUI rescans itself when you edit sources externally (mtimes are polled, like the original app): every cited manuscript-db member, emitted under the string you actually cited (full key or unambiguous prefix), so hash suffixes never need to appear in your .tex. astrobib refs [--prune] does the same from the CLI, first copying cited-but-missing entries into the manuscript db (--prune also removes uncited ones, rescuing sole copies). Co-authors don't need astrobib. They add a reference by pasting BibTeX from the ADS website into bib/any-name.bib (and, if they like, appending it to refs.bib by hand so the paper still compiles). Next time you check out the repo, astrobib tidy canonicalizes those files — re-keys them through ADS when needed, renames them to {Key}.bib, dedupes, rewrites the old keys inside your sources — and regenerates refs.bib for the commit. Migrating a manuscript that predates astrobib works the same way: in a directory with sources and its own loose .bib files but no bib/, astrobib tidy adopts it wholesale — builds bib/, resolves everything against ADS, rewrites your \cite keys in place, and regenerates refs.bib.

CLI

list, search [--ads], add <bibcode|ADS URL>, show <key>, rm <key> [--local-only] (sole copies rescued), import <file.bib> [--global-only|--local-only], refs [FILE] [--prune] [--dry-run], tidy [--dry-run], convert bibcode|full|short (uniform cite keys, rewritten in your sources), update [--all] (arXiv → published refresh, same key forever), config [ads_token|email <value>] (show or set the environment), gc (report what the machine-local caches cost), plus --library PATH (relocate the global tier) and --no-global. import resolves each entry against ADS (arXiv ID → DOI → exact title+author+year) unless its cite key is already reproducible from its own data — canonical astrobib entries import byte-identically — and prints copy-pasteable key replacements for your .tex files.
