I've loaded 425 items into
Google Base. That is the limit they currently impose.
Google Base is a place where you can easily submit all types of online and offline content that we'll host and make searchable online. You can describe any item you post with attributes, which will help people find it when they search Google Base. In fact, based on the relevance of your items, they may also be included in the main Google search index and other Google products like Froogle, Google Base and Google Local.
I searched our catalog for records with links to our Web site. Extracted a few fields that matched the ones Google accepts. Hint: a 4 digit year date is not enough, it requires YYYY-MM-DD. Then I loaded the fields into Excel and did a few global changes, removing the ISBD punctuation for the most part. Exported as a tab delimited file and uploaded into Google.
I'm hoping this exposes some of our resources better and increases our hits. Recycling information from the catalog, field 520 especially, should better inform Google searchers.
