Brian Leiter flagged some marvelous resources on his blog, which I will repeat here with one addition.
For good general information concerning publishing in philosophy and the job market:
For philosophy news and calls for papers:
- A newsfeed and Google Calendar.
- A Google Group for receiving calls for papers, news, etc. via email.
- (My addition) another list of upcoming workshops and calls for papers. Additionally, if your work could find a home in various disciplines (e.g. if you are doing philosophy of religion in such a way that might be of interest to religious studies departments) you can go to the root URL and look for calls for papers etc. in under other disciplines.
