There is much more to learn from reading the biographical and philosophical writings of leaders in higher education about what education for librarianship was and should be than from the literature of library education itself. This article contains an alphabetical list with annotations of 23 books on exploring the issues and problems of higher education. The list started as 12 and was referred to as "Shera's Twelve Apostles," and has now expanded to 23. The article concludes with a few titles that do not fall within the self-imposed limits of the bibliography, but ought to be mentioned as being important to anyone concerned with library education. [For the commentary on this article, "The Four Rightly Guided Caliphs. Commentary on Shera, J. (1969). Twelve Apostles and a Few Heretics," see EJ1073513.
