Abstract
Objective – To investigate
the implications of intended and actual usage data retrieved from a digital
library on digital library management and design.
Design – Case study.
Setting – A digital
library of predominantly high resolution images based at a large research
university in the United States of America.
Subjects – Responses from
917 users of an open access digital library.
Methods – Researchers used
a literature review to identify previous research on this topic and to inform
the methodology for their research. Two distinct studies informed the
methodology: research by Beaudoin (2009) that identified categories of both
users and questions around usage was incorporated, and the ultimate use
categories suggested by Chung and Yoon (2011) to compare against those used in
this research. Researchers used data extracted via recorded system logs that
are part of the statistics feature of the digital library. This feature is an
in-house developed system, the Digital Cart Service (DCS). The logs tracked
usage of 917 images recorded over a three year period, from 2011-2013. After
eliminating personal information, researchers examined three fields: university
affiliation, intended use, and description. After exporting the data from these
three fields to a Microsoft Access database for text analysis, researchers
normalized the data using a series of codes assigned to the responses. It is
unclear how many description fields were used to yield more information.
Main Results – Researchers
identified five user-types among users of the digital library. The biggest user
group was visitors, followed by university staff, while university faculty had
the lowest usage. Visitors were found to use images for personal use, such as
inspirational and artistic purposes. The products developed from images in the
digital library were-wide ranging, and included image albums, research,
artwork, and video productions. These findings have implications for four areas
of practical management of digital libraries: metadata creation, system design,
marketing and promotion, and content selection. Among the eight categories of
intended uses recorded, the highest uses were found to be for personal use,
followed by ‘other’ use. Researchers examined the ‘other’ use category and
further divided it into 12 sub-categories. Of these sub-categories, the highest
use was for publication and research, while the lowest use was for ‘gift’ and
‘industry.’
Conclusion – Incorporating
user-generated metadata and distributing it to digital library managers is
found to produce enhanced metadata and to aid the promotion and awareness of
collections. Usage data may inform marketing efforts, as it provides a more
comprehensive picture of who uses digital libraries and why they use images
retrieved from those libraries. Equally, usage data may reveal the least
frequent users of digital libraries, which informs targeted user marketing
campaigns. Finally, the authors find that usage data combined with
user-generated metadata should form part of content selection criteria for
digital library managers.
Commentary
This research adds to a small but growing body of
evidence about the use of digital images from digital libraries and how usage
may inform digital library management. At least one study has found that the
needs of users of digital images are not yet met (Kandiuk &
Lupton, 2012). The findings point to the analysis of usage data as a way of
identifying user needs.
Overall, this case study adheres to a good level of
validity when checked against Glynn’s (2006) critical appraisal checklist. The
authors note the limitations of the study, including the possibility of the
sample not being representative of the overall user population of the digital
library, or of all the uses of the data. The literature review successfully
builds on previous research methodologies, including coding schemes for image
use (Chung & Yoon, 2011), and the replication of three research questions previously
asked by Beaudoin (2014). Despite the integration of relevant methodologies,
the authors do not appear to have integrated recommendations of previous
research into their own digital library management practice. For example, two
recommendations found by the current study come from McCay-Peet & Toms’
(2009), who advised that information professionals develop more categories of
access points to aid image retrieval and to describe objects using both
conceptual and non-conceptual attributes. These recommendations are highlighted
in the literature review, and it may have been useful to revisit their
relevance in the discussion area of the article.
The DCS appears to be an innovative feature of the
digital library and may prove useful for other digital library managers. Since
the DCS is customized software, the inclusion of a screenshot of the DCS may
have enhanced the readers’ understanding of the practical use of image
retrieval from the digital library. A good description of the data extraction
and analysis is provided, and the categories used could be replicated by other
digital library managers. Results are clearly presented in six tables, and the
authors incorporate quotations from users about images used in practice.
The authors have made some important findings in this
case study that will be of interest to digital library managers and of special
interest to those responsible for digital images. Specifically, the integration
of user-generated metadata compliments indexing by library professionals. Where
this feature is possible, the metadata should be sent to digital repository
managers. User data informs system design and involves users in marketing and
promotion of digital image collections. Low usage statistics among categories
of users, as indicated by usage data, could directly inform targeted marketing
initiatives. The authors argue that ultimate use should be used as a selection
criterion for content inclusion. This may become more important over time, with
more usage data collected over longer periods of time. The authors continue to
investigate how usage of images can aid effective retrieval of images using
improved metadata. They have identified further topics relevant to digital
library management for future research.
