This book can also be partly viewed on googlebooks at:
https://books.google.fr/books?id=xl0jCgAAQBAJ&pg=PT335&lpg=PT335&dq=boudinet+cave+diving&source=bl&ots=Q1klbn0IMD&sig=kTLU1XJ8Sc-Lz8f5yqYsv7aaCZo&hl=fr&sa=X&ved=0CEUQ6AEwB2oVChMIhOa51bGtyAIVAn4aCh3yjArD#v=onepage&q=boudinet%20cave%20diving&f=false
or by typing keywords such as "cave diving" & "boudinet"
Regarding small quantities of books (two or three) I could as well sell them and ship them directly, and with a reduced price.
