While I read more online than anywhere else, I still like magazines, and subscribe to quite a few of them. Most are fairly well-known, like Prospect, Scientific American and the London Review of Books; you can find a lot of the content of these online also.
I wanted to mention a few less prominent Australian magazines which I subscribe to and find worthwhile. There’s Australian Options, published in Adelaide, Eureka Street from Melbourne and Dissent from Canberra. If you’re looking for a Christmas present for a leftish friend/relation, you could do worse than a subscription to one of these.
