1. There is a special person in the city library who is responsible for collecting overdue newspapers and magazines, which are available in almost every period, but they may not be sold to you.

2. The name and contact information of the printing agency will be printed at the bottom of the newspaper. I suggest you call them. There should be one there, too

Go directly to the newspaper office, they will have a lot of surplus newspapers. If these newspapers are disposed of, they will still have stubs.

4. Find the users who subscribed to this newspaper in the past few years. If they hadn't sold it to the garbage collector, they might have found it.

Others are hard to find unless you find a collector who specializes in collecting the newspapers you need.
