Determines whether an ISBN string is valid

lccn normalization (http://www.loc.gov/marc/lccn-namespace.html#normalization)
 +
1. Remove all blanks.
 +
2. If there is a forward slash (/) in the string, remove it, and remove all characters to the right of the forward slash.
 +
3. If there is a hyphen in the string:
 +
a. Remove it.
 +
b. Inspect the substring following (to the right of) the (removed) hyphen. Then (and assuming that steps 1 and 2 have been carried out):
 +
1. All these characters should be digits, and there should be six or less. (not done in this function)
 +
2. If the length of the substring is less than 6, left-fill the substring with zeroes until the length is six.
    +

Validate and format an issn.  This code fixes the case where an editor has included an ISSN in the citation but
  −
has separated the two groups of four digits with a space.  When that condition occurred, the resulting link looked
  −
like this:
  −
 
  −
|issn=0819 4327 gives: [http://www.worldcat.org/issn/0819 4327 0819 4327]  -- can't have spaces in an external link
  −
  −
This code now prevents that by inserting a hyphen at the issn midpoint.  It also validates the issn for length
  −
and makes sure that the checkdigit agrees with the calculated value.  Incorrect length (8 digits), characters
  −
other than 0-9 and X, or checkdigit / calculated value mismatch will all cause a check issn error message.  The
  −
issn is always displayed with a hyphen, even if the issn was given as a single group of 8 digits.

Validate and format an issn.  This code fixes the case where an editor has included an ISSN in the citation but

'<' and/or '>' angle brackets.

has separated the two groups of four digits with a space.  When that condition occurred, the resulting link looked

like this:

|issn=0819 4327 gives: [http://www.worldcat.org/issn/0819 4327 0819 4327] -- can't have spaces in an external link

 +
This code now prevents that by inserting a hyphen at the issn midpoint.  It also validates the issn for length
 +
and makes sure that the checkdigit agrees with the calculated value.  Incorrect length (8 digits), characters
 +
other than 0-9 and X, or checkdigit / calculated value mismatch will all cause a check issn error message.  The
 +
issn is always displayed with a hyphen, even if the issn was given as a single group of 8 digits.
