Wikipedia:Articles for deletion/International Marxist Tendency
the first source you cite is from Vonk which is IMT's affiliate in Holland so it's not an independent source. The second and third source, both from the same book, do not establish notability - the IMT is not actually mentioned in the body of the book but only in passing in two endnotes. Endonte 10 cites an article from the IMT's In Defence of Marxism website but says nothing about the IMT itself and if one scrolls up to endnote 10's origin in the body of the text on http://books.google.ca/books?id=3cU5ELUxXAEC&lpg=PA228&ots=tOaFwVPqSO&dq=%22international%20marxist%20tendency%22%20nyt&pg=PA7#v=onepage&q=%22international%20marxist%20tendency%22%20nyt&f=false page 7 there's no reference to the IMT whatsoever so this source does not establish notability. The second endnote, Endnote 243, is about Youth for International Socialism and mentions the IMT in passing and if one goes up to http://books.google.ca/books?id=5Bvn1dqVbIkC&lpg=PA88&dq=%22International%20Marxist%20Tendency%22&pg=PA88#v=onepage&q=%22International%20Marxist%20Tendency%22&f=false page 88 to see what is being endnoted it's actually about a Marx and Engels quote that is quoted in a Youth for International Socialism publication and again doesn't actually say anything about the IMT let alone establish its notability so the material you have provided does nothing to satisfy  or . Simply being mentioned in passing in the footnotes of one book is not sufficient to provide independent verification of notability
