Hollis+ is powered by ExLibris Primo technology.

The library has also posted this research guide/introduction/FAQ to Hollis+. It includes this slogan:

The guide includes this page about why the new service is worth using as well as an overview of what’s included:

…HOLLIS+ includes everything from the Harvard collection, like books, journals, maps, archival materials, videos and music.  HOLLIS+ also includes an enormous articles database, which has content from subscription databases and journals, along with open access content, like articles from the Harvard open access repository DASH.

Look for more posts in the future about the service itself and how it’s marketed to the Harvard community.
