The recently launched United Nations iLibrary is the place to go to search for content produced by the UN Secretariat and its agencies, funds, programmes and institutes.
The UN has produced, and continues to produce a large amount of research and data, but navigating to what's needed has not always been straightforward. The introduction of the iLibrary is a big step forward in terms of making content easier to find.
From the home screen it is possible to either carry out a search or browse for content - by theme, country or item type. As well as the basic search, there is an Advanced Search option which gives users the ability to specify the type of document, subject area, date range and language they wish to search across, and I would recommend trying out this option.
