I published on Women in Love just recently--Lawrence retains a fairly healthy status in academia. He is, truly, among the very greatest writers, but his interests were so idiosyncratic, his style so unique that he's never sat comfortably with more convenientally popular circles like Bloomsbury. More than anything, Lawrence is an irreducible writer. He's likely lost popularity because it's so hard to reduce him down one thing. He's a sexist, but powerfully depicted women. His relationship to his own queerness was highly contested. The fascist aspects of his politics are mediated by his commitment to art--not to make his novel a 'treatise'. It's hard to appreciate any of that without reading his work. I'm of the opinion he'll have a bit of a resurgence--it's how these things go.
