One of my favorite proof theory papers of all time:
W. W. Tait. Normal derivability in classical logic. In: Jon Barwise, ed., The Syntax and Semantics of Infinitary Languages LNM 72. (Berlin: SPringer, 1968), pp. 204-236.
Springer actually has this available online--which is neat, but of course only if your institution has access to the collection. Here's an excerpt from Lopez-Escobar's Zentralblatt review:

Looking through my CiteULike database today, I was reminded of this beautiful paper by Gallier, which tells you everything you wanted to know about the ordinal Γ0 and its proof-theoretic relevance. Section 6 is a wonderful overview of the theory of (constructive) countable ordinals.

New SEP entry on conditionals by Horacio Arlo-Costa:
This article provides a survey of recent work in conditional logic. Three main traditions are considered: the one dealing with ontic models, the one focusing on probabilistic models and the one utilizing epistemic models of conditionals.

The new LaTeX package turnstile lets you make fancy turnstile characters and put labels above and below the line (e.g., \vdash^x_L, but the right way).

Unfortunately, I didn't think of the title myself. It's the title of one of the workshops at the Calgary Folk Festival
, one where a bunch of artists play together, usually with an emphasis on the words (I haven't been, so I really don't know what they're like, but a few years ago they had Jane Siberry, Buck 65, and Friends of Dean Martinez, and that must have been amazing). Anyway, it would make a great title for a paper on proof speed-up, or for a proof theory or automated deduction conference t-shirt.

Can you help the ASL Committee on Logic Education? Please take this survey.
Dear Members of the ASL,
One of the responsibilities of the ASL Education Committee is to help its membership tackle pedagogical difficulties in teaching logic courses. In order to properly do this, we need to fully understand the goals such courses are intended to achieve. The focus of a logic class can be very different depending on whether it is in a mathematics, philosophy, or computer science department.

Below the funding statistics for grants in the Philosophy Committee for SSHRC Standard Research Grants. The explanation for why so few grants were awarded this year is pretty clear: rather than cut grants across the board, SSHRC decided to respond to the 23% cut in overall funding for the program over last year by making fewer awards. The overall success rate for all SRG's is down to 33% from last year's 40%. So it's not just philosophy that has suffered.

Skolemization is the familiar procedure by which you replace strong quantifiers in a formula by function symbols in such a way that A is provable iff AS is provable. This doesn't work in intuitionistic logic: the "only if" works, but the "if" doesn't. E.g., ¬¬(A(c) ∨ ¬ A(c)) is provable intuitionistically, but not ¬¬(∀x)(A(x) ∨ ¬ A(x)).

I'm at the Moscow-Vienna Workshop on Logic and Computation. We're on the second day. Yesterday was started off with a way-over-my-head talk by Sergei Adian on his and Novikov's solution to the Burnside problem. Today, Michel Parigot just gave a very interesting talk on a constructive, but classical proof system. His aim is to develop a system in which you can reason classically but still have nice properties like the disjunction property and the witness property.

Please read the following message from the President of the Association for Symbolic Logic. The terms of office of the editors begin July 1, by then information on how to submit papers should be online at the RSL webpage (not yet functional--but the submission email is email@example.com, I can tell you that much).

Yarden Katz writes per email:
There's a new site out -- videolectures.net -- where anyone can post videos of academic lectures. Right now it's dominated by (very good) machine learning and statistics lectures, but there's nothing on logic or philosophy. I was looking online for videos of logic-related lectures to add, but found virtually none. There are three links to logic-type talks by Martin Davis, Saul Kripke and John McCarthy at:

Recent posts on the status of women in philosophy made me want to know what the situation is in logic. In philosophical logic it's not good. I have a hunch that it's better in logic generally, but haven't had time to check this.
