I think you'd want to use xISBN, too, right?

Subject: [CODE4LIB] Automated searching of Copac/Worldcat

Apologies for cross posting

Dear collective wisdom,

I'm interested in using automation software such as Macro Express or iMacros to 
feed a list of ISBNs from a spreadsheet into Copac or Worldcat and output a 
list of those that return no matches in the results screen. The idea would be 
to create a tool that can quickly, although rather roughly, identify rare items 
in a collection (though obviously this would be limited to items with ISBNs or 
other unique identifiers). I can write a macro which will sequentially search 
either catalogue for a list of ISBNs but am struggling with how to have the 
macro identify items with no matches (I have a vague idea about searching the 
results screen for the text "Sorry, there are no search results") and to 
compile them back into a spreadsheet.

I'd be keen to hear if anyone has attempted something similar, general advice, 
any potential pitfalls in the method outlined above or suggestions for a better 
way to achieve the same results. If something useful comes of it I'd be happy 
to share the results. 

Many thanks for your help,
Nick
