Try something like this: put "xxxxxxxx" into tISBNnbr put "https://www.google.com/search?tbo=p&tbm=bks&q=isbn:<ISBN>&num=10" \ into tURL -- could store this as a customprop for general use replace "<ISBN>" with tISBNnbr in tURL put url tURL into tHTML and tHTML will contain the HTML for the google page, and you can parse this for what you want. What are you looking for? Parsing text strings is actually very easy and powerful in LC, once you get the hang of it -- you can extract pretty much anything you want. -- Peter Peter M.
