this book shows up on worldcat as being available but not the opl catalog:
Our holdings are only updated in OCLC periodically rather than in real time, so sometimes you will see items still in WorldCat that are actually no longer in our catalog (having been lost, withdrawn, etc.). That seems to be the case with this book. However, we would certainly be able to obtain it for you via interlibrary loan, if you would like to go that route. Here is information on how to do that:
I hope this helps!
