I'm not sure what to make of the article but, since it includes BLAS, it might be worth pointing out that scientific subroutine libraries are one of the most successful examples of reuse, particularly compared with more trendy things aiming at that. I can't remember if I ever actually linked ESSL (Engineering and Scientific Subroutine Library) on OS\370 but I remember it in the mid(?) 80s, when I don't think it was very new. These days I have it on POWER9 (if doubtless rather different). I don't know if it's older than the NAG library.
