The proper call number of Bahá'í literature is 297.89. The number 297 is given to Islam, and religions under that parentage are listed in that same general sequence. While the Bahá'í Faith is not a branch of Islam, our roots are in that faith, as the roots of Christianity were within Judaism. Most Bahá'í books published in North America under Bahá'í auspices will have the proper call number along with the copyright information inside the front cover.

It was recognized that the changing classifications of library listings is a very serious matter and once any change is made it must remain in effect a very long time in order to avoid the tremendous confusion that frequent changes and revisions would create in the library system involving thousands of local public libraries throughout the country.
