This work reviews and compares the literature about ITSM practices in libraries, public administration, commercial sector and e-Science infrastructures. Six aspects taken out were properties or structure of digital components, source of finances to support the daily running of business in these sectors, forms of organization, frameworks developed in the form of guidelines to structure the sectors, the factors that influence implementation of ITSM guidelines. It was found out that though there are similarities between all of these sectors, yet the case of e-infrastructures is special and practical implementation of ITSM practices is needed.
