Accessing Ancient Historical Texts

Hello,

I am a fan of Korean Culture, especially ancient Korean historical texts. I understand that these texts can sometimes be a pain in the ass to access, and sometimes images of said texts aren’t accessible to the public. I know that Kyujanggak, Jangseogak, the National Central Library of Korea, as well as Kostma.korea.ac.kr and ugyo net are all sites that store ancient Korean texts, but I’m talking more about ancient texts stored in Ehwa, Goryeo, Seongkyunkwan, Yonsei, Sogang universities: they don’t have any digital versions of the text that I can easily view, and I want to access them. Now I know that sometimes they do scan the texts if I give them money, but the money I have isn’t Korean, and to register an account I sometimes need to have Korean Credit Cards and Korean identity cards or whatever, and I obviously don’t have that. So is there any way I can view these texts without going to Korea?
