There are seven copies in the UCD Architecture library in Richview, including one in the Reserve Collection, i.e. it can only be viewed in the library. So even if the other six happen to disappear between now and then, that one will be there.
If you’re not in Dublin, you can get it on inter-library loan. If you’re not a UCD student, you can still get into the library anyway to see the book.
If this link doesn’t work, go to the UCD website, then the library page, then do a search for the title.
