Over on his art blog, illustrator Harry Borgman posted an interview he did for The American Artist Book Club back in 1977. It's a short but interesting piece that not only covers Harry's line and ink techniques but also briefly touches on his influences and how he became an author of art books. It's a short read and worth checking out. Read Harry's interview about ink line drawing.
If you would like additional information, you might recall back in January of this year Harry put together a detailed account of his successful career as an illustrator. Read the Illustration Pages autobiography of Harry Borgman.
