"Pawn Structure Chess" by Soltis and "Chess Structures: a Grandmaster Guide" by Flores have good coverage of 1. e4 structures as well as 1. d4 structures. For the Sicilian, the French, and the Spanish, there are books from an out-of-print series "Mastering the ... " that focus on the pawn structures from those openings.

No love for "Pawn Power in Chess" by Kmoch?
My omission of Kmoch was inexcusable. It does have excellent material on e4 structures. Thank you for adding it.
In a previous discussion, someone reported a passage from Pawn Power in Chess by Kmoch: "The lengthening of the rearspan is often favorable, inasmuch as the expansion of territory behind the pawn increases the freedom of the pieces. By the same token, the shortening of the frontspan limits the freedom of the opposing pieces."
I'm not exactly a big fan of that sort of writing, but there nevertheless seems to be a widespread opinion that the Kmoch book is worthwhile.
"... [Pawn Power in Chess] should be on everyone's list [of favourites]. ..." - GM Nigel Davies (2010)
Another point of view:
"... Hans Kmoch’s Pawn Power in Chess is considered a classic by many. Nonetheless, most people found it daunting and confusing, given its weird terminology. Also the scope of the book was more theoretical than practical; not an easy book to read and study with. ... must be frustrating to read and study from for those rated below 1700. ..." - Stephen Ham (2000)

Is there an equivalent book for 1. e4 players to Sokolov’s Winning Chess Middlegames? That is based mostly on structures arising from d4 openings. I have Chess Structures, which is very good, but wondered if there was something more in-depth on the openings following 1. e4?
Thanks
