I have received numerous reports via various channels regarding a number of archives denying access to post-1949 materials. I have updated the PRC History Resources wiki to reflect these:
I also added updated information regarding several other archives. We all know that archival access can be tricky in China, but recent changes are particularly distressing, with no end in sight.
If you have news to pass along that is not yet on the wiki, feel free to post here or send me a direct message and I will further update. As always, I keep the wiki entirely anonymous, and do the vast majority of the updates myself in order for it to remain so.
