Laurie Penny (In science fiction, the future is feminist, 14 June) writes enthusiastically about female sci-fi writers of past and present, deploring their dismissal by sexists and literary snobs, but does not mention the brilliant book that first introduced my generation and now Laurie Penny’s to many of those writers – In the Chinks of the World Machine: Feminism and Science Fiction, by Sarah LeFanu, first published in 1988.

• Print it any size you like, but do keep your paper edition (Size matters, but not as much as content, Letters, 19 June). My daughter tells me that it’s inadvisable to wipe breakfast marmalade from fingers on to an iPad. And re Barbara Kelly’s letter on the same page, I’m 82, and enough was enough a long time ago for me. I joined Momentum as soon as it was formed.

• Re Bob Dylan’s plagiarism (Letters, 19 June): “Immature poets imitate; mature poets steal,” wrote TS Eliot (The Sacred Wood). Shakespeare, of course, was on to this.
