Good study materials for invasions?

[Time]

I am about 3d aga (haven't played a ton in the last few years other than the past month, but can play about even at 2d tygem). I am looking for good material to study basic invasion "joseki". For example, in The Middle Game of Go, Sakata shows a lot of joseki for reducing/invading against the keima and ogeima enclosures. Also, After Joseki has many sequences similar to what I am looking for.

Are there any other books in particular that cover this sort of topic well in english or any online resources which have this information?

How about "Get strong at Invading"?

Attack and defense has a fairly detailed chapter on invading 3-space jumps. There is also some material on invading larger frameworks, but there is a much heavier focus on reducing.

There's also a book called 'sabaki' by yang yilun. can't recall the specifics, but it's what you're looking for; invasion joseki.

If you want joseki, you could look at Enclosure Joseki by Takemiya Masaki. It's out of print, but there's a Kiseido digital edition. It is..exhaustive.

Slate and Shell had a book called "Keshi and Uchikomi: Reduction and Invasion in Go" but sadly it's out of print.

Yilun Yang's [sl=FundamentalPrinciplesofGo]Fundamental Principles of Go[/sl] has a nice chapter about invasion of many common shapes. The rest of the book is good too, I like his style of teaching.

All about Life and Death vol 2 has a chapter on invasions but again the book is out of print.

I am about 3d aga [...] basic invasion "joseki"

Please specify which kind of invasion josekis you want! Early corner josekis? Middle game invasions? Only such middle game invasions that are josekis?
