A conference says on its call for papers website that: "papers will be part of the Conference Proceedings (if the authors wish to do so), but they will not be uploaded to IEEE Xplore." -- What does this mean exactly? If I agree for it to be in the proceedings then will I be able to find it using the ISBN of the conference? Will it have a DOI (I highly doubt, but still wanted to know)?
Thank you in advance. I appreciate your time and consideration.
