They are accepting entries for the 7th Annuel (2006) contest from 1 November to 31 December. The announcement is here. The FAQ list is here on the SCGS site.
The types of articles desired are described here:
* What Kind of Articles Do You Want?
The contest is for factual articles: either family-or local-history, character sketches, or memoirs. The entries should capture a sense of a family’s experience(s), or the character of a locality, or reveal an individual’s character and personality. The best articles will help illuminate the human drama—and will also illuminate the era, and/or the historical or social context of the subject.
* What Kind of Articles Do You NOT Want?
Accounts of genealogical research procedures, “how-to articles,” advice, and/or general genealogical columns are not appropriate for this contest.
If you like to write, and can satisfy the requirements, I urge you to submit one or two entries. One of my genealogy friends, Paula-Jo Cahoon, was a winner in an earlier contest with her story of "Fany".
