In this work, the terms that best represent the training in competencies the last 30 years (information literacy, information library / computer literacy, internet , digital and technological literacy) are considered as two clusters. After consulting three specialized databases (LISA, LISTA, ERIC) three multi-disciplinary databases (ISI, FRANCIS CINDOC) a quantitative qualitative analysis has been done, considering as a first stage, the period 1997-2007, as a second stage of update, the 2008-2009 period. The analysis has identified the increasing importance of the training acquisition of competencies, given the increasing volume of such publications. However, when performing the cluster analysis, which upgrades updates the previous work, it is shown how at different times there is a preference for certain terms or competencies. Also this type of analysis evidences that, although there are some studies that have defined, differentiated classified the skills the technology, presented as complementary previous level the second, in many subject areas this differentiation is not so clear there is less emphasis on competencies from today's perspective (information literacy and/or information skills), which means for professionals to continue working for the positioning, both at educational entrepreneurial level, the need for continuous training in competencies as the key to lifelong learning.
