Published: December 2018

Librarians need to be able to read critically published
accounts of educational and training interventions
(ETl) and to apply the results to their own practice.
One mechanism for assisting library practitioners in
doing this is the critical appraisal checklist. This article
describes the process of developing such a checklist -
involving a literature review of existing frameworks
and experience in appraising such studies for a
systematic review of information literacy skills training.
The ReLIANT instrument is offered as a first attempt
to equip library practitioners with a tool for use when
appraising published reports of educational and training
interventions.

Academic researchers' use of the Internet, and their consequent support requirements.
Authors: Jacobs Neil 
Published: December 2018

Because the lnternet has become such a pervasive
information medium, the Library at Sussex
University decided to investigate how local
academic researchers were using it in their work (if
at all), and thereby to assess their support
requirements. A total of 30 academics were
interviewed, and the results indicated that the
appropriate support arrangements were
decentralised and discipline-based, in terms of
staffing, training and maintenance of a local lnternet
'gateway'. These results are in line with those of
research on related topics.
