Somwhere, sometime in my life in Serials, I read, saw, or heard, the
rule-of-thumb that if a publication has more than 4 or 5 names on
the route slip a second subscription should be purchased.

>From my own experience here where some serials (Byte for instance)
has 15 people on the Route slip this would make eminent sense.
However, I have failed to find anything published that I could show
as evidence that multiple copies for more than 4 or 5 readers is not
just my own wishful thinking..

Does anybody know of something in print that I could use as back-up
to this position?

warm regards,
