Acquiring old books

[Casanova]

I want to get the issues leading up to Exhibition File 6 by Murasaki Syu. Always wanted to know the build up to that beautiful story.

The problem is these were released in 1999-2002. The artist's Dlsite and other online outlets have only his new works.

How do I go about procuring these books? Any suggestions?

You see, someone got most of Suehirogari's works and got them scanned and most of it is on the net even if not translated. Someone even got most of Kaimeji Yuu's works from those years and older. So, what is the way to get these books of Murasaki Syu from that time if it is no longer in production? Get it from some random stranger in Japan who has it and then scan it?

If you look at the time most of these were uploaded it starts from somewhere around 2007-08. So any ideas?
