I would suggest using Connexion's Batch Search to pull records as a first pass. Something like ti:title and au:creator and yr:year and dt:sco and lv:(b or i or 1) When looking for the best record with more than one result with such a large project, I sometimes use z39.50 to grab the OCLC records through MarcEdit. Doing so will include a field that records the number of institutions using that record - the hope being that the more popular a record is, the more likely it is to be accurate.
