I don't know the full context either since I've never read
the work, but hope to find it in the state library next week. MG told me it's out of print.

I just checked the library database. It was first published by MacMillan in 1951 and the last print was in 1972. The database prefix denotes that the book is irreplaceable from source (out of print) so ye cannae get it from the shops.
