2013年、60周年を記念してNew General Service Listが作成されていたんですね。v1.01が最新版になるでしょうか。さっそくこのリストでOxfordとLongmanにかけてみたところ以下のような結果となりました。1000語というのは派生語などをまとめたもの。語数が多い方はreのような縮約形や複数形などの活用形も一つの単語とみなしたものです。

Words checked = [1000]
Words in Oxford 3000™ = [100%]

Words checked = [3197]
Words in Oxford 3000™ = [95%]

Word count: 1000; Percentage in wordlist: 92.7%

Word count: 4197; Percentage in wordlist: 89.2%

New General Service Listは無料公開されており以下のサイトからダウンロードできます。動画を参考にすれば簡単です。データの元となるcorpusもCambridge English Corpusを使ったようですね。日向先生のGSL本はどのリストをベースにしているのかわかりませんが、2013年に出たNew General Service Listなら間違いなさそうですね。

With approved use of the two billion word Cambridge English Corpus, Dr. Charles Browne, Dr. Brent Culligan and Joseph Phillips have created a New General Service List (NGSL) of important vocabulary words for students of English as a second language . The first version of this interim list was published in early 2013 and provides over 90% coverage for most general English texts (the highest of any published list of high frequency words to date with the 1.01 version of the NGSL often getting over 92% coverage). Please feel free to browse around the site, download the list in various forms, read articles about how it was created, and try out the large and growing number of free online learning tools, teaching tools, analytical tools, editing tools and EFL textbooks which make use of the NGSL.

A New General Service List: Celebrating 60 years of Vocabulary Learning
In 1953, Michael West published a remarkable list of several thousand important vocabulary words known as the General Service List (GSL). Based on more than two decades of pre-computer corpus research, input from other famous early 20th century researchers such as Harold Palmer, and several vocabulary conferences sponsored by the Carnegie Foundation in the 30s, the GSL was designed to be more than simply a list of high frequency words, its primary purpose was to combine both objective and subjective criteria to come up with a list of words that would be of “general service” to learners of English as a foreign language. However, as useful and helpful as this list has been to us over the decades, it has also been criticized for (1) being based on a corpus that is considered to be both dated, (2) being too small by modern standards (the initial work on the GSL was based on a 2.5 million word corpus that was collected under a grant from the Rockefeller Foundation in 1938), and (3) for not clearly defining what constitutes a “word”.
In March of 2013, on the 60th anniversary of West’s publication of the GSL, my colleagues (Dr. Brent Culligan & Joseph Phillips of Aoyama Gakuin Women’s Junior College) and I (Dr. Charles Browne, Meiji Gakuin University) announced the creation of a New General Service List (NGSL), one that is based on a carefully selected 273 million-word subsection of the 2 billion word Cambridge English Corpus (CEC). Following many of the same steps that West and his colleagues did, we have tried to combine the strong objective scientific principles of corpus and vocabulary list creation with useful pedagogic insights to create a list of approximately 2800 high frequency words which meet the following goals:
1 to update and greatly expand the size of the corpus used (273 million words compared to the 2.5 million word corpus behind the original GSL), with the hope of increasing the generalizability and validity of the list
2 to create a list of the most important high-frequency words useful for second language learners of English, ones which gives the highest possible coverage of English texts with the fewest words possible.
3 to make a NGSL that is based on a clearer definition of what constitutes a word
4 to be a starting point for discussion among interested scholars and teachers around the world, with the goal of updating and revising the list based on this input (in much the same way that West did with the original GSL)

Is There a Core General Vocabulary? Introducing the New General Service List

New General Service Listについて論考はでているのでいろいろ読んでみようと思います。とやかく言うのは早い段階かもしれませんが、OxfordやLongmanの基本語リストと重複しているものが多いということは、もしOxfordやLongmanの辞書やGraded Readersを使っているならそのまま使い続ければいいんじゃないでしょうか。基本語に限定された定義語を読むことがそのままGSLで選択した基本語の習熟につながるということですからね。
