I had a heck of time with Belgium and ended up recataloging the entire country. I buy a new volume each year and over the course of 4 years I get a new set. It works just fine for me. But I will not part with my 1990 complete set since I use that to price any minimum valued stamps. From time to time the magazine also has lists of stamps with particular topics, so the magazine would also be useful for topical collectors.
Single issues are available in stamp shops etc.
When the new Michel Overseas series starts, the catalogs will be reorganized into 10 parts. The Falkland Islands and Antartic territories are moved from South America to Australia, and Malaysia is moved from the Australia part to the new part 10.
