WorldShare Collection Evaluation circulation files

The file name should include:

  • No spaces in the file name
  • The institution symbol of the library submitted the file (e.g., OCC)
  • A date stamp indicating when the file was submitted in "YYYY_MM_DD" format (e.g., 2016_07_12)
  • Do not use special characters in file names, such as ~ ! @ # $ % ^ & * ( ) + = - / ' " [ ] { } | \

Methods of creating unique file names

  • You can combine these methods or use another
  • Add the date to the filename
  • Add a serial number to the end of the file: myfile1, myfile2

Multiple files

  • If you send more than one file per day, each file must have a unique name.
  • If you send multiple files with the same name in the same day, only the last one sent will be retained and processed.
