Zotero, Google Books, and Research

As of late, I've been trying to figure out if it is worth our while to put Google Books links in our catalog records. First, I ran a search on all of the books in our stacks from 1850-1923, and then sampled them randomly, first three per every other page, and then one every ten pages. I got a sample of around 250 or so titles.

I copied the bibliographic information from PEAK using the Firefox 2.0 extension Zotero, which automatically detects and pulls bibliographic data off most websites. Currently I am checking how many in my sample are in Google Books, and double-checking them against the catalog, thanks to tabbed browsing.

So far, Google Books has matched Peak to the tune of 39%.

UPDATE:
The final count is 88 out of 243, or 37%.
