Abstract. The availability of SWS data from the Infrared Space Observatory is a landmark in the study of interstellar ices. This paper presents a brief review of what was known prior to the launch of ISO, and attempts a synthesis of what has been learned from the ISO observations available to date. Key areas of uncertainty are identified to provide a basis for future research.

Key words: ISM: molecules - dust, extinction - infrared: interstellar: lines - stars: pre-main sequence

* Based on observations with ISO, an ESA project with instruments funded by ESA Member States (especially the PI countries France, Germany, the Netherlands and the United Kingdom) and with the participation of ISAS and NASA.
