Sometimes I take a risk with a magazine I see on eBay that purports to have a Wing Commander article that isn't available online. This circa 1997 copy of UK-based PlayStation Solutions magazines (Vol. 1, Issue 5 of the US version) seemed like it might have something worthwhile as it has Wing Commander IV as a cover story and promises a complete guide to the game. The actual article ended up being somewhat disappointing, four pages of information taken mostly from the game's then-active official website. But I scanned a copy for posterity anyway, so enjoy!
The magazine also includes a simple two-page spread for something called an "Electronic Arts Competition" which offers, among other prizes, a copy of Wing Commander IV.
