13-Digit Barcoding

 

Hyphenation Instructions

There are various reasons to generate the hyphenation
at output by programming:

  1. To reduce work at input, by reducing number of characters
  2. To eliminate manual checking of hyphenation
  3. To ensure accuracy of format in all ISBN listings and
    publications (regardless of the format submitted by the publisher)

 

For correct presentation, the 10 digits of an ISBN must
be divided, by hyphens, into four parts:

  • Part 1: The country or group of countries identifier
  • Part 2: The publisher identifier
  • Part 3: The title identifier
  • Part 4: The check digit

The position of the hyphens are determined by the publisher
prefix range established by each national agency in accordance
with the industry needs. The knowledge of the prefix ranges for
each country or group of countries is necessary to develop the
hyphenation output program.

The publisher prefix ranges in the
English group (U.S., U.K., Canada, Australia, New Zealand, etc)
are as follows:

Group                 If Number Ranges    
Identifier "0"          are Between      Insert Hyphens After
----------------------------------------------------------------------------
00------------19            00-19        1st digit     3rd digit   9th digit
200-----------699           20-69              "       4th   "           "
7000----------8499          70-84              "       5th   "           "
85000---------89999         85-89              "       6th   "           "
900000--------949999        90-94              "       7th   "           "
9500000-------9999999       95-99              "       8th   "           "




Group                 If Number Ranges   
Identifier "1"         are Between      Insert Hyphens After
--------------------------------------------------------------------------
00------------09            00-09       1st digit     3rd digit  9th digit
100-----------399           10-39           "         4th  "           "
4000----------5499          40-54           "         5th  "           "
55000---------86979       5500-8697         "         6th  "           "
869800--------998999      8698-9989         "         7th  "           "
9990000-------9999999     9990-9999         "         8th  "           "


The following table gives the range distribution of the group identifiers:

                           0 - 7 
                          80 - 94
                         950 - 993
                        9940 - 9989
                       99900 - 99999


The following table is an example of the range distribution of publisher
prefixes. Assuming a group identifier of one digit only, the publisher
identifier ranges might be as shown in the left hand column and the title
identifiers as shown in the right hand column.


Publisher Identifier          Numbers Available for 
                              Title Identification
        00-19                    1 000 000
       200-699                     100 000
      7000-8499                     10 000 
     85000-89999                     1 000  
    900000-949999                      100
   9500000-9999999                      10
