Alarums and Excursions (A&E) is an amateur press association started in June 1975 by Lee Gold (at the request of Bruce Pelz, who felt that discussion of Dungeons & Dragons was taking up too much space in APA-L). It was the first publication to focus solely on role-playing games.
Each issue is a collection of contributions from different authors, often featuring game design discussions, rules variants, write-ups of game sessions, reviews, and comments on others contributions. It was a four-time winner of the Charles Roberts/Origins Award, winning "Best Amateur Adventure Gaming Magazine" in 1984, "Best Amateur Game Magazine" in 1999, and "Best Amateur Game Periodical" in 2000 and 2001.
Although game reports and social reactions are common parts of many A&E contributions, it has also, over the years, become a testing ground for new ideas on the development of the RPG as a genre and an art form. The idea that role-playing games are an art form took strong root in this zine, and left a lasting impression on many of the RPG professionals who contributed.

From their website:
A&E is a laser printed monthly roleplaying game APA (amateur press association) with contributors from across the US, UK, and Canada. It was runner up for the Charles S. Roberts Origins Awards in 1981 and 1982, and won in 1985, 2000, 2001, and 2002.
A&E was begun back in 1975. It skipped one month in the first year while Lee Gold was in Japan, and another month in 2006 when she was recovering from major surgery, but has come out regularly every month otherwise. Maximum length is 150 pages, no advertisements; issues usually run 60-80 pages.
A&E is not affiliated with any gaming company. Contributors are interested in many different games. They are also interested in cultural and military history, fantasy and science fiction, rock music, military re-enactments, movies, martial arts, murder mysteries, filksongs, science fiction fandom, religion, physics, astronomy, and a number of other subjects, all of which can be easily tied into roleplaying games if you take a sufficiently creative approach.
