The collection contains more than 600 papers, and has a collected #almetrics attention score \cite{Kwok_2013} of almost 900. The number of ratings and recommendations, however, is still minimal, but the NSC community is welcome to leave comments. Articles in the collection can be filtered by, for example, publisher or journal and sorted on, for example, #altmetrics attention score and citation count. The background image of the collection originated from an Open Access figure from a paper from Carmen Vogt et al. \cite{Vogt_2015}

Next steps

The collection currently has articles up to 2016. However,  the cluster is currently not systematically collecting DOIs (although the Research Participant Portal reporting system does have that option and certainly collects published outputs). The OpenAIRE platform (https://www.openaire.eu/) has started collecting output (article, but also software and data publications) \cite{Houssos_2014}, but does not have a complete list either and is not limited to only the NSC. Therefore, collecting DOIs of more recently literature is high on our agenda within the Database Working Group of the NSC (https://www.nanosafetycluster.eu/working-groups/4-database-wg.html). Second, we have started discussing integration with data infrastructure. For example, we are exploring if it is possible to create links between NSC articles and entries in the eNanoMapper database. But this requires better data integration between the resources. For now, links to follow up papers, data, etc, can be provided as comments to the paper.
To complete the collection, NSC projects are kindly invited to email DOIs of papers funded by that project to egon.willighagen@gmail.com.  The collection itself has a DOI too, and thus can be cited with DOI 10.14293/S2199-1006.1.SOR-UNCAT.CLVVPKP.v1 \cite{Willighagen}.
