Nanotechnology
journal collection
in
HKUST Library
Expand aggressively the scope and extent
of electronic resources,
Especially e-journals and web-based
reference tools
Nanotechnology is a rapidly growing
academic field
Interdisciplinary in nature
Nanotechnology is a major area of
research in HKUST
Users of the collection are mostly researchers and PG students.
The collection is composed of mostly e-journals.
This evaluation concentrates on e-journals.
Collection-based Use- or User-based
Quantitative Book counting, Budget analysis, etc.
Circulation statistics, Journal usage statistics, etc.
Qualitative List checking, Citation analysis, etc.
User surveys, Focus groups, etc.
(based on Johnson, 2004)
Local statistics : Usage statistics – e-journal, circulation, book
request logs, ILL, DDS, etc.
National/international statistics: Journal citation report, journal usage report by ISI Journal citation analysis by Scopus In-cites Google Scholar …
JCR
Data 1
Journal Citation Report by ISI, Thomson research services Impact Factor (IF) – impact upon the research
community
COUNTER
Data 2
A standard for generating and exchanging
usage reports
Most useful for e-journals usage
Generated monthly by vendors/publishers
to subscribers (libraries)
We focus on Number of full-text access
HKUST Library is using a system called
JURO to keep and manage the COUNTER
data.
This COUNTER report summary lists all titles found in JCR.
The titles are ordered in the same manner as the JCR, sorted in descending order by Impact Factor.
There are a few unavailable or print-only titles for which no usage statistics are available, but are inserted to the usage report for direct comparison between the two tables.
Most titles found in JCR are heavily used in HKUST Library
during the years.
Titles having high JCR impact factors tends to be accessed
more often in HKUST Library; titles having impact factors
lower than 1.0 tends to be less often used
Those journals showing "lower" usage are actually not too
underused if we compare them with the overall e-journal
usage of HKUST Library
During 2006, 35% of all e-journals were never used at all!
• There was another 35% of e-journal lightly used, with an access count of 1 to 10.
• The majority of journals found in JCR are heavily used (in the top 7% usage among all subscripted e-journals).
Look for journals with high IF
Investigate any new and forthcoming journals
Consult users
Other libraries’ holding
Weeding the zero usage counts?
Be suspicious with statistics data
Consult potential users
Weeding the low impact factors?
Be aware that JCR does not cover recent
data
Serving users’ needs should be a priority
Weeding the useless ones?
1/3 of all e-journals were not accessed
Bulk purchase, inelastic subscription
contracts
Libraries want more flexible subscription
arrangements
lower cost, less manual work fast, timely results objective repeatable can be done more frequently closer monitoring of the collection health faster response to the needs of users, to the needs of
the community/institution that the library belongs faster response in updating decisions in collection
development and management, in acquisition and weeding
Usage statistics of non-circulating printed
items, especially printed journals, are
difficult to collect.
Base on existing usage dataBase on citation analysis reportsMathematical and rule-based
Data collection
Data processing Evaluation Report
Save librarians from monotonous and
laborious list checking work
Allowing them to concentrate in their
professional judgment to making
collection development decisions
