Scripts manipulating bibs to properly roll up in Vega

Running the script

$ python manipulate.py [path to src marcfile] [path to output file]

The script produces three files:

• processed marcfile - MARC21 recods successfuly processed with modified 240
• processed.csv - a list of bib #s, 245s, and new 240s output the marc file
• skipped.csv - a list of bib #s and 245s skipped by script

Strategy

• consider only bibs that have $n in the 245 field but no equivalent in the 240
• consider only print materials (BIB MAT "a")
• consider only branch materials (910 $a BL)
• ignore complex cases:
  • presence of other than $a$n$l subfields in the original 240
  • no digits in $n of the 245 (example: Book two, Volume IX, etc)
  • typos that concatenate words with digits, example: Book2
• will use a special load table ("ut") that modifies only a selected tag
  • records used will have only a minimal number of tags: leader, 008 (?), 240, 245, 907, 949 (command line with load table to be used instruction)
