They are not on Anna's Archive or on MaM. They are available for digital purchase from SpringerPub or Amazon.
Is there a different tracker for textbooks and reference materials?
How likely is it that a request will be fulfilled. Would someone need to buy the book themself and upload it?
Not a perfect solution but when I needed specific obscure and/or new editions for coursework, I'd go check out my university library's copy and photograph all the pages I needed
it's common for universities to keep a reserve copy (or a few) of any books required by courses. access may be limited (e.g. at my school you could check them out only 2 hours at a time). If your library has a book scanning station your life will be easier so ask if they have one.
One time after class I ran into a classmate trying to do the exact same thing, so we ended up taking turns sharing scan photos to save ourselves time the rest of the semester. Be sure to share the love with any fellow ultra-broke classmates
happy sailing 🏴☠️
