My university requires that I upload my PhD thesis to ProQuest. ProQuest charges $95 for "open-access" publishing, while "traditional" publishing is free. I want to confirm my understanding here. "Open access" in this context really just means that ProQuest will make the PDF available in perpetuity for free. However, it does not mean that I cannot host or disseminate my thesis myself or use other open-access services, such as my university's library or arXiv. Does anyone know if this is correct? I’m pro-open access publishing, but I’d like to avoid paying this $95 fee.
Clarifying edit: This is not a duplicate of this question. That question is about the distinction between two different grades of open access publishing. My question is about whether or not I am interpreting a specific (and massive) open-access publisher's policies correctly. I've also edited my title to be more clear.
