本科論文的中文資料

Not sure if this is the place to ask, but… I'm currently about to start writing my Chinese bachelor's thesis. Does anyone have any suggestions for good places to find Chinese sources? My thesis is specifically about efforts to promote Mandarin as the national language in Mainland China and its effect on the usage of other Chinese dialects. 如果有建議可以提的話，以下請留言一下。
