[HISTORY]

The interest has its own history and is closely related to my radio history, or better to say it's a direct reason why I got so impressed and interested in radio industry myself, and later on became a DJ/radio personality.

A long long time ago... one late day back in 1983 I found "American Top 40" on one of the most popular radio stations in Europe at that time, Ö3. I became an instant fan of the show, then presented by Casey Kasem and during years listening became huge passion, resulted in collecting "American Top 40" (Billboard) chart listings through the 80's. 
Later when Casey was replaced with Shadoe Stevens in late 80's and early 90's, he started his own Top 40 show called "Casey's Top 40" (based on Radio & Records weekly airplay charts), I continued with collecting these charts, instead... from mid 90's I even started collecting "Rick Dees Weekly Top 40" (also R&R based) charts as a result of discontinuing of "Casey's Top 40" broadcast on VoA.
Casey returned inlate 90's to"AmericanTop 40" with AM/FM Networks, later to become Premiere Radio Networks,and with huge internet coverage of american radio stations I could nowfollow both Casey and Rick Dees.
In 2004 Casey stepped down as a host of "American Top 40" and RyanSeacrest took after Casey to host new "AT40", while Casey continued tohost "American Top 20" (HotAC charts) and "American Top 10" (ACcharts - Top 10 from March 20'th 2004). After 39 years of counting downthe hits Casey Kasem retired on July 4'th 2009 when Premiere discontinued AT20 and AT10.
Casey's original shows from 1970's and 1980's can still be heard on theradio as a part of the Premiere Radio Networks "Casey Kasem presentsAmerican Top 40 (The 70's)" and "(The 80's)" series.
Rick Dees left Premiere Radio Networks  for X Radio Networks in January 2005 and issince then using his own charts (probably based on affiiliatesairplays). Since January 2009 Rick is back with ABC Radio Networks thatused to distribute his shows during the 1990's.

Today I own basically every "American Top 40" chart listing from first weekly chart of 1980 to date:
80's "Billboard" based
90's "Radio & Records" based (CT40/WT40/AT40)
2000 to 2004 "Mediabase 24/7" - "Radio & Records" based
2004 to date "Mediabase 24/7" AT40 airplay affiliates based

[TRADE]
Many "American Top 40" fans, including myself, collect original radio shows such as "American Top 40", to preserve a piece of radio history.
As those shows are relatively hard to find and quite expensive, fans started trading shows to help each other grow their collections. I am as well a part of this community.
Below is the list of syndicated chart shows in my collection.
At this point I own all "American Top 40" shows from July 4'th 1970until the end of its original run in 1995.

If you would like to trade:
My primary intention is to collect one show per each month (f.e. see AT20 2006 collection below).
I am willing to trade on 1:1 show basis, only on optical media, such as CD-R or DVD-/+R (only mp3/wma).
I prefer good quality recordings: recorded from original CDs or vinyls.
I am curently (as of 2006) only trading online and can offer ftp upload/download trading: mp3 or wma format (at least 160k quality).
If you want to trade or wonder about anything else that's not stated here, please, contact me (if you have any other questions).
