Out of the 8 algebra books which I've checked, I have only found 1 which deals with the semidirect product: the one by Dummit & Foote.
Are there any other books which talk about it? Thanks.

@DonThousand Herstein, Gallian, Artin, Scahun, Fraleigh, and a few more – Ovi Nov 16 '19 at 19:57

1See for example here, or here. There are many books treating semidirect products. I can offer my notes, too. – Dietrich Burde Nov 16 '19 at 19:58

@DietrichBurde Thanks! I'll take a look. – Ovi Nov 16 '19 at 20:05

More likely to find it in a book that just does Group Theory than in a book that tries to cover all of Algebra, I think. – Gerry Myerson Nov 17 '19 at 01:31

Why not wiki? I think this page https://en.wikipedia.org/wiki/Semidirect_product already contains enough information about it. Anyway it's not a complicated notion... – WhatsUp Nov 17 '19 at 01:35

It seems that there is something relevant in this list (search of "semidirect product" in google books). – Pedro Nov 17 '19 at 17:57
