I found three publications dealing with the selection of e-resources for libraries.
An interesting article, Evaluating E resources by Bleiler and Livingston (2010) provided details acquired from a survey of 73 institutions regarding the criteria used for selection of these resources. The most highly rated criteria was uniqueness and completeness of content, followed by usage rate, user friendliness and relevance.
The criteria of content is also an important one for Johnson (2012) who states that the content of an e-resource should be of a “certain quality” and “compliment or add depth to the current collection”.
Content is also important according to McGeachin (1998) who suggests that the e-resources quality should be at a ‘proper intellectual level’ and be ‘accurate and presented in an easily accessible manner’.
The content of an e-resource should be of high concern in terms of selection. The content needs to be evaluated according to how it will add depth and further support the other resources within the collection, the e-resource needs to be a reliable source and the content needs to be presented in a way that it is accessible and user friendly.
