Read about Collector Booklets

My 1996 Scott Standard Postage Stamp Catalogue, Volume 4, arrived in late July 1995. Ignoring all the extraneous stuff at the front, I promptly flipped to South Korea's latest catalogued stamps. The last catalogued New-Issue, was the Jan. 21, 1995 "Protection of Wild Animals & Plants (2nd Issue)", a two stamp issue at Sc# 1801 & 1802. I was surprised to find the remarks, "Souvenir booklet, 4 #1801" and "Souvenir booklet, 4 #1802"; but, not until I read the footer-remark, "Booklets of Nos. 1801-1802 each have one stamp tied to cover with first day cancel."; did it dawn on me that Scott had begun cataloguing South Korean Collector Booklets. I found one other like remark, after perusal of previous pages of the catalogue; Sc# 1797, 1994's "Philately Week Special".
See Scott# 1801 & 1802, on page 128.
See Scott# 1797, on page 127.

I immediately telephoned the Scott Publishing Co. and after the usual formalities, I was connected to Scott's New-Issues Editor, at the time. He explained that Scott planned to catalogue all South Korean Souvenir Booklets as Scott acquired them, to place in their "Reference Collection". I remember that the Editor sounded some-what surprised, when I provided the following information, that I had gleaned:
   a. That the Booklets began being released sometime in 1989, so Scott had a long way to go.
   b. That the Booklets were released by a third-party contractor to the Stamp Issuing Authority; i.e. "The Korean Philatelic Center", which was obviously selling the Booklets at a surcharge of 500 won (roughly $.50) above the stamp cost, contained.

When my 1997 Scott Standard Postage Stamp Catalogue, Volume 4 arrived, the last catalogued New-Issue, was the Mar. 5, 1996 "Protection of Wild Animals & Plants (3rd Issue)", a two stamp issue at Sc# 1865 & 1866.
See Scott's page 122.

A search showed that there were thirty (30) new "Complete Booklet" remarks, after those identified for the 1996 Scott. Seven (7) of the catalogued "remarks" were for Type 1-Souvenir Bookets, leaving 23 "Remarks" for the Type 2-Portable Booklet, which began being released with the July 24, 1995 stamp issue. The catalogue makes no mention of the Booklet format change.

When my 1998 Scott Standard Postage Stamp Catalogue, Volume 4 arrived, the last catalogued New-Issue, was the Dec. 2, 1996 "1997 New Year's", a two stamp issue at Sc# 1893 & 1894; erroneously catalogued with the issue-date of "1997, Dec. 2".
See Scott's page 154.

A search showed that there were thirteen (13) new "Complete Booklet" remarks, after those identified for the 1997 Scott, and 121 new "Complete Booklet" remarks, other than those identified for 1996 & 1997, with the earliest shown at Sc# 1535 the May 27, 1989 issue. Plus, a new "Souvenir Booklet Box", has been added at the bottom of Page 145. The "Souvenir Booklet Box" does not contain any Sc# of the Type 2-Portable Booklets remarked.
See "Souvenir Booklet Box" on page 145.
