Conversation so far:
When was the New York Public Library's website created?
January 7, 2010, New York, N.Y., The New York Public Library has launched its new Drupal-based website, at http://www.nypl.org.
Could you tell me something about the New York Public Library website, please?
The NYPL website provides access to the library's catalogs, online collections and subscription databases. It also has information about the library's free events, exhibitions, computer classes and ESL classes
What else does the New York Public Library website have besides access to the library's catalogs, online collections, subscription databases, and information about the library's free events, exhibitions, computer classes and ESL classes?
The NYPL gives cardholders free access from home to thousands of current and historical magazines, newspapers, journals and reference books in subscription databases, including EBSCOhost and The New York Times.

Question: what are digital holdings?
