I describe all this not as an advertisement for Olive (although it's a fine magazine), but for the contrast it presents to all the other journals to which I subscribe. Mill News is occasionally accompanied by pretty little pamphlets and maps; this month's was extra-special - it came with a pamphlet containing an essay of particular interest to me - almost like getting a little book free with it.
Beyond those, to claim the rest of my journals come with freebies is to stretch the concept a little too far. Once in a blue moon, a press will pay to have an advertising flier included with one of them. Isis includes a once-a-year extra bibliography volume. AHA membership comes complete with a surfeit of newsletters. Beyond that? Well, you get what you pay for in the underfunded world of semi-commercial academia.
Inspired by Olive, I've been daydreaming recently about all the fun little freebies which could arrive in my mailbox every few months. Isis could give away a glossy, make-your-own astrolabe one month. Renaissance Quarterly might arrive with a sample of vellum, from an appropriate advertiser. Speculum's plastic wrapping could enclose a set of nicely-printed medieval recipe cards. (Collect them all!). Technology and Culture could come with a replica miniature nineteenth-century board game. Well-thought-out freebies are usually worth receiving.
Alas, given the business model under which academic journals operate and the lack of heavy-duty advertising revenue behind them, it's not likely to happen anytime sooner. But I can dream.
