Challenges in creating an international, company-wide 'virtual library'

Topic: 

GlaxoSmithKline (GSK), the world's largest pharmaceutical company embarked on an ambitious virtual library project a few years ago.
Last year I had the opportunity to speak to two GSK librarians about this project, and to me they are a best practice for other company libraries.

"Research Information" has an article online about GSK's virtual library project. In the article, you learn about the challenges they met during their journey. Highly recommended reading for company librarians !
