This Review describes, with 200 references, progress with ion-selective electrodes, membrane electrodes, and ion transfer voltammetry in the period between January 2013 and September 2015. The selection of papers was done at the author's discretion and should therefore be understood as an opinion piece and a current snapshot of the activity in the field. Contributions were sourced from modern search engines, primarily SciFinder, searching for relevant keywords and known author names. Some journal tables of contents were also screened manually. Please accept my apology if a reader feels that his or her important contribution has been left out. Perhaps I simply did not see it.
