  The Astrophysics Source Code Library (ASCL) is a free online registry of
research codes; it is indexed by ADS and Web of Science and has over 1300 code
entries. Its entries are increasingly used to cite software; citations have
been doubling each year since 2012 and every major astronomy journal accepts
citations to the ASCL. Codes in the resource cover all aspects of astrophysics
research and many programming languages are represented. In the past year, the
ASCL added dashboards for users and administrators, started minting Digital
Objective Identifiers (DOIs) for software it houses, and added metadata fields
requested by users. This presentation covers the ASCL's growth in the past year
and the opportunities afforded it as one of the few domain libraries for
science research codes.
