Here is the first main chapter of the Study Guide, on First-Order Logic. Nothing much has changed in the recommendations (or the occasional disparaging comments about non-recommended books!). However, the surrounding chat has been tidied up. I have in particular heeded a friendly warning about “mission creep” (the overview sections were getting too long, too detailed — especially about various proof-systems). So I hope the balance is improved.
One comment (which I have also now added to Chapter 1 — the section on “Choices, choices” where I say something about how I have decided which texts to recommend). If I were choosing a text book around which to shape a lecture course on FOL, or some other topic, I would no doubt be looking at many of the same books that I mention in the Guide; but my preference-rankings could well be rather different. So, to emphasize, the recommendations in this Guide are for books which I think should be particularly good for self-studying logic, without the benefit of classroom introductions or backup.
