A new mobile app introduced this week by the New York State Bar Association lets lawyers search and access ethics opinions from their mobile phones. The NYSBA Mobile Ethics App includes the state bar’s catalog of more than 900 legal ethics opinions, dating back to 1964.

The app allows users to search for an opinion by keyword, retrieve it by opinion number, or browse a list of categories such as “attorney advertising,” “concurrent representation” and “non-refundable retainer.” Results show both a digest of the opinion and its full text. It can notify you when new opinions are added.

The free app is available for iPhones, iPads, Android phones and BlackBerrys.
