Google Book Search: Boons and Banes
You're probably not big into antedating - the academic game of finding earlier citations of words and phrases. But here's an interesting tale, because it shows the pros and cons of Google Book Search:this discovery is typical of how Google Book Search now provides limited assistance to participants in what Erin McKean recently called "the competitive sport of antedating." Bonnie Taylor-Blake happened upon the relevant volume of Car Life but had no way of determining the precise context or even the correct issue and page number because of the limitations of Google's "snippet view." Fortunately, the metadata for this record includes accurate volume information ("v.9 1962-1963"), which allowed Bonnie to zero in on the correct page in a library copy of Car Life.
In other words, Google Book Search tantalises the antedater by showing earlier uses, but makes it awkward if you want to pin down the details. This is yet another reason why we need full-text open access to all books: otherwise, imagine the antedaters' anguish.
