Description:

IBList - Sort unordered lists (books, etc) into alpha order.
On www.iblist.com Lists of books/series etc. are ordered by copyright date & database entry nbr#.

This default sorting can make it difficult to (a)Find a book by title (b) Spot duplicates (c) and/or perform linkdev match-up operations from IBDoF.

This script sorts the lists alphabetically and provides a warning if it finds a potential duplicate entry.

  DESCRIPTION
  Lists of books/series etc. are ordered by cpyrt. date & db entry nbr#
  This script sorts the lists alphabetically
 
   Check for volume numbering and sort numerically - not as ascii chars
  Do not sort numbered series - curse the template designer
  - damned unusual way of turning unordered lists into ordered items

  If titles are identical (within the list being tested), raise an alert
   as they may be duplicate entries.
