Over the next few months, I'll get a listing of what's needed for the database when it comes to reporting numbers for Statement sof Ownership. Just the number itself is helpful -- but the other stats an be useful in other analyses.
You may also find that there are no Statements in a specific year that's being explored. That's important to know, as it allows me to cross it off the list.
Currently, I believe that as many as 3,600 statements bearing circulation numbers may have appeared in as many as 350 comics titles since 1960. The database currently has at least the main sales number from more than 2,500 of them -- but where I only have the sales number, I'll still want to get the rest of the info from the report.
Anyway, I'll have the list together soon. Stay tuned...
