Search Error Messages Sometimes a Bookreader search generates error messages. Most errors occur when Bookreader is unable to open a book or bookshelf. The major causes of these errors are the following: * The user does not have the required privileges to open the book or bookshelf. For example, this can occur when you try to open a bookshelf file in another directory and the owner has restricted the protections on the file. * Bookreader cannot locate the book or bookshelf. For ex- ample, this can occur when there is an erroneous entry in the bookshelf file, or Bookreader files have been deleted from a directory referenced by the bookshelf file. * The user is not authorized to read the book because nei- ther the product license nor the Bookbrowser license is loaded. * The search involved books on the ConOLD disc, and either the CDROM drive is not on line or the correct ConOLD disc is not mounted. When Bookreader encounters errors during a search, it dis- plays all the error messages in the Search Messages Box at the conclusion of the search.
