Not available on the ebook places?

I feel like these must be academic publications? They tend to be ridiculous cos they are aimed at university libraries who will pay. 

 Not that I could find! But I did find this collection of 670+ ebooks https://image.nostr.build/97a5cbcb0038b3fdfcddc226386ea160eef011c7672053001a1ebc03b3fa8050.jpg  

 Couldn't see it on zlibrary but searching author did being up other books by them:( 

 Same with soulseek. Some other Barbara Yorke books there, but no luck
