Deciding which databases will bring the most value, benefits and unique content into a library collection can be challenging. One of the most important steps in evaluating different full-text journal databases for purchase is choosing the appropriate comparison service.
In order to be valuable to librarians in making educated collection development decisions, a comparison service must take into account several important factors:
How database providers reflect full-text content information (title name, ISSN, etc.) in their published title lists
Understanding "actual" versus "intended" content
The importance of "active" over "halted" coverage
The availability of unique content in each resource considered
The significance of human interaction/oversight at every level of the comparison process
