About antilibrary
Save any page to your antilibrary BibTeX library — auto-extract metadata, add tags, and optionally download the PDF/EPUB.
Detailed description
antilibrary turns your browser into the front door of your reference library.
One click on the toolbar saves the current page as a clean BibTeX entry in the
library of your choice — no copy-pasting citations, no leaving the page.
It reads your local antilibrary config, so the same libraries you use from the
command line and Emacs show up right in the popup.
What it does:
• Pick a library — choose which of your BibTeX libraries to save into, or use
the quick-save shortcut to drop straight into your default.
• Smart metadata — scrapes the page's citation tags, Open Graph, JSON-LD and
title into a proper BibTeX entry. Ordinary pages become tidy @online
bookmarks with a unique cite key.
• Authoritative entries for papers — if the page is a PDF/EPUB or carries a
DOI, arXiv ID or ISBN, antilibrary resolves it for a precise, canonical entry.
• Tag as you save — type comma-separated tags in the popup and they're written
to the entry's keywords field.
• Keep the file, not just the link — tick "Download file & copy into library"
to grab the PDF and file it into your library's folder, named after the cite
key. The path is stored on the entry.
• Quick-save shortcut — press Alt+Shift+S to save the current page to your
default library instantly, with a confirmation notification. Rebind it at
chrome://extensions/shortcuts.
• Edit before saving — optionally review and tweak the title, authors and year
before the entry is committed.
Requirements: antilibrary is a companion to the open-source antilibrary toolkit.
It talks to a small native helper that you install once on your computer
(pip install 'antilibrary[all]', then register the native messaging host). The
extension does the page; the helper writes your .bib files locally. Setup
instructions: https://github.com/vxvware/antilibrary.chrome
Open source (MIT). Your data never leaves your machine — see below.
Single purpose
Save the web page the user is viewing as a BibTeX reference (with optional file
download) into the user's local antilibrary bibliography, via a native helper
the user installs.
Permission justifications
• activeTab — to read the title, URL and citation metadata of the page the user
explicitly chooses to save when they click the toolbar button or press the
shortcut.
• scripting — to run a small content script on that page, on demand, that
collects its citation/Open Graph/JSON-LD metadata for the BibTeX entry.
• nativeMessaging — to hand the collected entry (and any downloaded file) to the
locally installed antilibrary helper, which writes it into the user's .bib
library on their own computer.
• notifications — to confirm the result of a quick-save (Alt+Shift+S), since
that flow has no popup window to show success or failure.
• Host permissions are not requested broadly; the extension only accesses a page
when the user invokes it (activeTab).
Data usage disclosure
This extension does not collect, transmit, or sell any user data. Page metadata
and any downloaded file are sent only to a native helper running on the user's
own machine to write local BibTeX files. Nothing is sent to the developer or any
third-party server.
