I am searching for a paper that contains the origin of an approach. but when I searched in internet, I couldn't find it as PDF format.
What is the solution to access papers like this?
At many universities they offer so called "inter librarian loan" - don't know if that's available, that helps a lot for hardcopies and publications you can't find. Also check if you can find the authors email address and contact them for a copy.
In your case, just search the journal title on Google - go on the Journal website - search the Archive.. and you'll find that they got it free of charge. Takes about 3 minutes.

Thanks dear Michael
you are right. It was my mistake that I didn't search in correct way. I went to the journal website but I couldn't find it.
However, I appreciate your answer about finding a hard copy.
Approaching the authors is very important as Michael mentioned. They may also provide you additional material related to the stated subject. I have benefited a lot from such communication. Cheers!
Dear Stanislaw
Please come to my country and show me these places! I will appreciate you!
I often find this a nice opportunity to sen the authors an email explaining what I am trying to do and asking for a pdf reprint.
Thank you Dr Raczynski
The first post has solved the problem. But the question was not about a typical paper. I asked to know more about these matters.
You know, when your country is under sanctions you will have many problems in resources accessing.
