Here's an excerpt:
We are reassured that libraries are exposing their data in multiple ways. Although the catalog is the first method of exposure (76%) and other methods of local exposure rate high such as the institution’s Web site (67%) and the institution’s digital repository (68%), a relatively high percentage exposes metadata through union catalogs (63%), crawlers like Google, Yahoo, MSN (56%), and OAI-PMH harvesters (48%). Small percentages expose data to SRU/SRW queries (5%), Flickr (10%), and YouTube (2%). We wonder whether these percentages will increase over the next few years.
