The Catholic National Readers were originally published in the 1890s by Benziger Brothers Publishing. They have been reprinted by Savio Books and Neumann Press in 1997 in hardcover editions. They are frequently compared to the McGuffey's Readers and are illustrated with charming pictures of the sort you'd expect to see in "antique" books. Because of the sometimes archaic language and vocabulary, some homeschoolers (particularly those with more reluctant readers who want stories that are a little easier and a little more fun) prefer the American Cardinal Readers or the Faith and Freedom Readers. The Catholic National Readers are used by Kolbe Academy, Our Lady of Victory School and St. Thomas Aquinas Academy. Kolbe Academy sells some study guides that accompany the books.
