Abstract
An exemplary book indexing system according to the invention includes an index table (10 or 12) which has thereon a first series (23) comprising names in alphabetical order of book chapters or similar parts to be indexed, and a second series (24) comprising numbers in non-numerical order, one number of the second series being aligned with each word of the first series. A plurality of tabs (13) each bearing one of the numbers in the second series (24) may be attached to appropriate pages of a book (10) so that the chapters thereof may be quickly referenced. A tab layout strip (14) aids in placing tabs (13) manually on book (10.) The indexing system according to the invention is especially useful for books such as the bible which are frequently cited by the name of the biblical book in which a passage appears.
