Five free routes (+ one paid)
Ranked by real-world speed1. Libgen.li mirror
Click GET on the libgen.li page — gives you a direct CDN link. No throttle, often 5+ MB/s. Best free route for most files.
2. IPFS gateway
Anna's Archive lists IPFS CIDs. Public gateways (dweb.link, w3s.link, 4everland) serve them directly. Best second-bet when libgen is sluggish.
3. Local IPFS node
Run ipfs daemon (or IPFS Desktop). ipfs get <CID> bypasses every gateway rate-limit. Slowest startup, fastest steady-state.
4. Anna's slow servers
"Slow partner" download — free but capped at ~20 KB/s with hourly cooldown. Only as last resort, or for <5 MB files.
5. Z-Library (Tor)
z-library.sk via Tor browser. Daily download limit on free account; no throttle on speed.
(Donor) Fast servers
Anna's Archive accepts a small donation for unrate-limited fast partner servers. Not free, but bookmark this if your time is worth more than $5/mo.
Workflow
Five steps to a local PDFGet the MD5
From an Anna's Archive page like annas-archive.gl/md5/<hash>. Copy the 32-character hex string and paste above.
Hit "Hunt"
You get a ranked mirror list. Top mirror in green = fast partner server (libgen.li). Yellow = IPFS gateway. Red = throttled fallback.
Click the top mirror
It opens in a new tab. Libgen pages need one extra click on the GET button — that lands the direct download.
Save to _books/
Drop the file at unomaha-fall2026/_books/bennett_cosmic.pdf (site root). Reader's fetch("../_books/…") hits that path automatically; annotations restore via SHA-256 hash.
Open the Reader
If the file's in _books/ the textbook page status pill turns green. Otherwise the file picker in Reader will accept it manually.

localStorage — never leaves this browserWhy the libgen.li GET button isn't a direct link
Each "GET" page generates a one-time key (?md5=…&key=XXXXXXXX) and the file URL behind that key expires in minutes. Hunter fetches the ads.php page, scrapes the current key, and gives you a fresh direct link. If a link 404s after sitting too long, just re-hunt.
