For what it is worth, both the
Mexicana Journal and the
Israel Philatelist have been digitized by their respective societies and are available on-line or DVD to members. This has reduced the need for physical copies of either journal (I am a member of both groups). The primary disadvantage of these digital editions is that in some instances, the quality of the scanned publication is not a sharp as the original.
I second the suggestion to donate them to a local philatelic organization if there is one in your area, or the staff of a philatelic show committee if you have a show. Their best use will be to "tease" new collectors into considering those countries as a collecting area.
The MexiMail Forum, at
www.meximail.org is active but not nearly so much so at this SCF. I monitor it regularly, post occasionally, and you "might" find someone who would be interested in the
Mexicana Journal issues there. I've not encountered any problem with accessing it or logging on, but if you have trouble, contact me via this thread or directly and I'll see if I can help.
I have one room filled with philatelic journals I can't bear to part with, even though I have many in digital format as well. I still like the feel of paper!
At some point the future, my son will likely wish I had been more proactive with disposing of these while I was still alive and kicking!
