PubMed problem
MYTH: Google Scholar searches Medline FACT: Google Scholar does not search Medline.
It searches whatever Medline records NLM happened to give Google. We have no idea when NLM gave Google the records. We can't anticipate when the next batch will be delivered and the Google Scholar database updated.
My results showed that Google Scholar failed to retrieve any PubMed content after February-March 2004

Currency – an example
How current is the indexing?To answer this question we looked at the most
recent issues of nursing journals at the Blackwell’s site. On average, Blackwell nursing journals were indexed on Google Scholar over two-and-a-half months before they show up in CINAHL.

One answer to my question
a free, easy to use, subject based, deep mining metasearch service whereby you can easily find papers, quality websites, books, technical reports, jobs, industry news, standards, eprints, learning resources, patents, etc.(from another USTLG member)

Some conclusions
Useful - at an appropriate level – eg undergraduate - despite deficiencies. Remember: user needs or wants; exhaustive or sufficient search
Improvement on Google. Users will find it – its easy to use too.
Can help direct users to library databases/journals. Is information finding important now or information
using? What is the librarian’s role? It’s a Beta version - so not finished, so…
Keep watching - it will get better
