for the uninitiated, google have a research platform, scholar.google.com.

for the uninitiated again, there are librarian jobs which require PhD and masters. Some of these roles are masters in computer science, where the person develops the whole computing library platform. Like the national libraries in US keeping archives of historical artifacts requiring high security worth millions and billions. The PhD people fall into the information keeping of libraries. These can be anything from data-mining to data organization and artificial intelligence using the vast amount of texts.

Librarian is not just the housekeepers you see at NLB.
