Ex: We can choose to turn our backs on these principles with fatuous arguments which posit their anachronism and the nonexistent intelligence of computing machinery.

Ex: The training of users of On-line Public Access Catalogues (OPACs) should be attuned to the characteristics of the system = La formación de usuarios de los catálogos en linea de acceso público (CEAP) debería estar en consonancia con las características del sistema.

Ex: This study found that online access to scientific serials is most appropriate in the third world, principally due to the presence of a small number of scientists with a broad range of interests which makes the fixed-price regimes of print, microform or CD-ROM disadvantageous.

Ex: Teachers need to be more familiar with bibliographical ways and means: librarians should be more aware of problems from the teachers' perspective and make active efforts to inform teachers of sources of help.
