This article reports results of a study that used an in-depth comparative content analysis to assess free-text and controlled vocabulary collection-level subject metadata in three large-scale digital libraries in the European Union and the USA.

Article on the interplay over time among mobile computing, commerce and applications. The study performed is a co-word analysis for a corpus of 4821 SCI/SSCI indexed papers related to mobility in the Web of Science (WoS) database from 1995 to 2013. The emerging concepts demonstrated in the strategic diagrams and the associated co-word structures have implications for future research.

This paper analyzes the relationship between subject terms -- both authorized terms from controlled vocabularies and free-text keywords -- used to succinctly describe the content of the electronic theses and dissertations (ETDs) and the search terms entered by users to discover and access the ETDs. Identification of search terms and comparison of search results with subject terms used in describing ETDs provides a basis for assessing the relative usefulness of controlled-vocabulary subject terms supplied by professional indexers and free-text keywords supplied by authors of ETDs in facilitating access to ETDs. Arguably, there has been a shift in the way users search, access, and use information resources.

This presentation presents results of a study that analyzed representation of dates and time in one of the largest aggregators of digital content in the world -- the Digital Public Library of America (DPLA). The findings demonstrate both similarities and differences in date and time representation across DPLA content hub and service hub provider groups.
