This is the first 2017 issue of the Summary of the ISC Bulletin, which remains the most fundamental reason for continued operations at the ISC. This issue covers earthquakes and other seismic events that occurred during the period from January to June 2017. Users can search the ISC Bulletin on the ISC website. The monthly Bulletin files are available from the ISC ftp site. For instructions, please see the www.isc.ac.uk/iscbulletin/. This publication contains information on the ISC, its staff, Members, Sponsors and Data providers. It offers analysis of the data contributed to the ISC by many seismological agencies worldwide as well as analysis of the data in the ISC Bulletin itself. This issue also includes seismological standards and procedures used by the ISC in its operations. Notably, this issue contains brief information on the recently released last portion of the Rebuilt ISC Bulletin for the period 1991-2010 that replaced the original ISC Bulletin data. From now on, all ISC hypocenter solutions (1964-present) are based on the ak135 velocity model and all ISC magnitudes (1964-present) are based on the latest robust procedures. We continue publishing invited articles describing the history, current status and operational procedures at those networks that contribute data to the ISC. This time it is the turn for the seismic networks run by the
