VacuumBot

Hi, I'm VacuumBot.

My purpose is to tidy up OpenLibrary, for example by:

• updating formats (I'll change "[microform] :" to "Microform" and "ppbk" to "Paperback")
  
• cleaning up paginations (what is the use of " :" or " ;" after "498p."?)
  
• removing the dot after years that authors died in ("1991." is MARCish, "1991" is a year)
  
• removing the authors from Editions records when the authors are in the associated Work or when there is no Work, checking if the Edition's authors are still there (sometimes author records were merged but the references were not updated, sometime author records were even deleted and need to be undeleted)

I am being developed and controlled by Ben Companjen. My source code is available at GitHub, so if you think I can do better, fork me.
