What this browser can open, and how to open it elsewhere.
This browser
Not signed in — the free tier: Part I of the book, the sources, the library and the evidence. A licence opens the rest; see what is free and what is not.
Licensed, but on a new device?
Your licence follows the browser that bought it. To open it here instead, enter the email you paid with (temporarily by hand — see below) and follow the link it receives. No password — the mailbox is the proof.
Sign-in mail is being set up. Until it is live, write to v.s.sajesh@gmail.com from your payment email and access is restored within a working day.
Proof reader
Invited to proof-read a manuscript? Enter the access key you were given; the books allocated to you open under Proofing.
