+_DESCRIPTION = """\
+PubChem (https://pubchem.ncbi.nlm.nih.gov) is a popular chemical information \
+resource that serves a wide range of use cases. In the past \
+two years, a number of changes were made to PubChem. Data from more than 120 \
+data sources was added to PubChem. Some major highlights include: the \
+integration of Google Patents data into PubChem, which greatly expanded the \
+coverage of the PubChem Patent data collection; the creation of the Cell Line \
+and Taxonomy data collections, which provide quick and easy access to chemical \
+information for a given cell line and taxon, respectively; and the update of \
+the bioassay data model. In addition, new functionalities were added to the \
+PubChem programmatic access protocols, PUG-REST and PUG-View, including support \
+for target-centric data download for a given protein, gene, pathway, cell line, \
+and taxon and the addition of the `standardize` option to PUG-REST, which \
+returns the standardized form of an input chemical structure. A significant \
+update was also made to PubChemRDF. The present paper provides an overview of \
+these changes.
