[H3] What We Do
LibriVox volunteers record chapters of books in the public domain, and then we release the audio files back onto the net for free. All our audio is in the public domain, so you may use it for whatever purpose you wish. Please note: Our readers are free to choose the books they wish to record. LibriVox sees itself as a library of audiobooks. Because the books we read are in the public domain, our readers and listeners should be aware that many of them are very old, and may contain language or express notions that are antiquated at best, offending at worst.
Volunteering for LibriVox is easy and does not require any experience with recording or audio engineering or acting or public speaking. All you need is a computer, a microphone, some free recording software, and your own voice. We accept all volunteers in all languages, with all kinds of accents. You’re welcome to volunteer to read any language you speak, as long as you can make yourself understood in it. You don’t need to audition, but we do suggest a 1-Minute Test recording just to check your setup. We’ll accept you no matter what you sound like.
We operate almost exclusively through Internet communications on our forum, where all your questions will be answered by our friendly community.
For more detailed information, see our FAQ.
We’d like your help. Click to learn about volunteering for LibriVox.
[H3] Resources and Partners
We get most of our texts from Project Gutenberg, and the Internet Archive hosts our audio files (for free!).
In early 2010 we ran a fund-raising drive to raise $20,000 for our expenses for the next few years. In July 2013 we launched a new fund-raising drive with the goal of raising $50,000 for short and long term expenses. If you would like to help, please visit our Donate Page.

Your Diagnosis

Before revealing the machine’s verdict, predict the BS score for each signal. Higher = more BS (more fluff, less verifiable substance). Drag each slider, then submit to compare your judgment against the engine.

Information Density 0 / 30
Read the Narrative & headings: do hard facts (prices, dates, numbers) outweigh fluff power-words?
Semantic Coherence 0 / 20
Compare the homepage promise against the sub-page reality. Do they hold the same line?
Trust & Proof 0 / 20
Weigh review mentions against actual external proof links. Claims without verification = theatre.
Commodity Fingerprint 0 / 15
Check headings & narrative against the industry clichés in the setup above.
Identity & Authority 0 / 15
Inspect the schema: is there real Organization/Person identity with sameAs links, or gaps?
Your predicted BS score 0 / 100
💡 Stuck? Reveal the heuristic lens — how the deterministic page-auditor reads each signal (no AI, pure pattern rules)

These are the structural rules a local, deterministic auditor applies — the same lens you can use to judge each signal. They describe what to look for, not this company’s result.

Information Density

Classify each sentence as substantive or hollow. Grounding markers — numbers, currencies, dates, technical units, named entities — outweigh marketing adjectives. When fluff sits right next to hard evidence, the fluff is forgiven.

Semantic Alignment

Pull the main entities out of the H1, then check whether they actually recur through the body. A page that announces one thing and then talks about another drifts. Headings with no real sentences underneath read as pseudo-substance.

Trust & Proof

Count trust words (review, testimonial, rating, verified) against real outbound proof links (Google, Trustpilot, Clutch, G2, Yelp). Lots of trust language with zero verification links is trust theatre. Unlinked logo galleries count against it.

Commodity Fingerprint

Look at how much sentence length varies. Natural writing varies its rhythm; templated or mass-produced copy is statistically uniform. Very low variation reads as commodity content — unless unique named entities break the pattern.

Identity & Authority

Inspect the JSON-LD. Is there an Organization or Person schema, and does it carry sameAs links to real external profiles (LinkedIn, socials)? Missing schema or no identity declaration signals an anonymous entity.

Want to apply this lens yourself? The free BS Indicator Chrome extension runs these heuristic checks live on any page. Bear in mind it is a single-page, deterministic tool — it relies only on pattern rules for the page in front of it and does not perform the cross-page semantic correlation this audit uses, so its readout is a starting lens, not the full verdict.

BS Detector

Media, News & Publishing BS: LibriVox (librivox.org)

https://librivox.org 📍 Industry: Media, News & Publishing
25 BS / 100

LibriVox is a high-substance, low-fluff entity that suffers from technical rot and temporal neglect. It is functionally the opposite of modern corporate BS: it provides massive value with almost no marketing jargon, yet fails to provide the modern structured data and updated proof required to verify its current authority.

Immediately implement JSON-LD Organization schema on the homepage and Person schema for the founder on the About page to bridge the technical authority gap. Update the funding and statistics sections to reflect data from the last 12 months, as the current 2013 references suggest a defunct project. Add outbound links to the specific articles mentioned in the ‘In the Press’ section to convert trust theatre into verified proof. Consolidate redundant H3 tags that repeat the ‘free public domain’ phrase to improve heading hierarchy.

The site aligns perfectly with the Media, News & Publishing category, specifically focusing on the niche of public domain audiobook distribution. The content consistently references editorial status (Complete, Collaborative, Solo) and source material (Project Gutenberg), confirming its role as a digital publisher.

“The score of 25 is driven primarily by the Identity and Authority pillar (8/15) due to missing schema, and the Trust and Proof pillar (11/20) due to extremely stale fundraising evidence and unlinked press mentions. The site performed exceptionally well in Information Density and Semantic Coherence, preventing a higher BS score.”
