Some Oricon album history
 

So I was compiling a week-by-week charting and sales list for Namie Amuro (including Suite Chic), MAX, Ayu, Koda Kumi, BoA, Ami Suzuki and Utada Hikaru from the archives on Oricon's historical albums charts. However, I ran into a snag, where they've failed to post the top 30 for the following weeks (well at least i keep getting a message that says something like "Traditional Top 30 for So and So Month so and so week is not available" or something like that) :

2006
December, Week 1
December, Week 4

2007
January, Week 4
February, Week 3
March, Week 4
April, Week 1
April, Week 4
June, Week 3
July, Week 3
September, Week 3
September, Week 4
October, Week 1
October, Week 3
November, Week 1
November, Week 4

2008
January, Week 4
February, Week 1
February, Week 2
February, Week 4

Does anybody have these specific weeks' archived somewhere or know the sales figures for them. I'm not too clear on publishing dates for each chart, but if you know what I mean, please help. It would be greatly appreciated. Thank you.
