8. Introduction of Unicat
 UNICAT is the National Serials Union Catalogue and
Books Union Catalogue in CAS for the CHINA research
community
In 1983,1989 and 2002 be supported by Funding of
CAS, MOST and CAS
UNICAT is a freely available tool to help both
researchers and librarians locate serials held in the
China, books held in the CAS
It contains serials bibliographic and holdings information
from over 400 China research libraries, including
university Libraries and military Libraries
It contains books bibliographic and holdings information
from over 60 institute libraries in CAS
Print and electronic forms are all in it

10. How important are E-journals?
 96.1% of Science journals are online
 86.5% of Arts and Humanities are online
 2006-2007 –102,000,000 downloads
Up 21% from previous year
 17% usage is at the weekend

14. How does it work
 To develop member libraries in share principle
 Centralised database based on oracle DBMS
 Member libraries provide data by Z39.50 protocol or web
browser
 There is a team in CAS to manage data and control data
quality
 Member libraries can download bibliographic record
 Users in member libraries can visit Unicat system freely

15. Member Libraries

19. System development strategy
 To get a funding for two years from CAS to establish a
online catalogue for print journals and books
 Functional requirement
 Application software
 Custom developed
 Data exchange format support MARC21 and CNMARC
 Give up 856 field to describe electronic linking
information, to design metadata to describe complex
object
 Based on member libraries’ address to support
IP
sensitive fulltext linking
 Support DDS and ILL of CAS

25. Questions
 Now e_journals and e_serials have replaced p_journal and
P_serials to become main holding in libraries. See some
libraries statistics. Case:
Engineer library of University of Stanford Case
Library of University of Tsinghua
Etc.
 which role will be played by union serials catalogue?
How to find roadmap
E_serials union catalogue ?
Knowledgebase ?

27. Question
 I find more value of Suncat in controlling data quality, it is
helpful to certify unique title of serials and to provide
accurate information for knowledgebases
 OpenUrl router being a middleware, its benefits for service
providers and libraries are obviously excellent
 There are currently 95 Institutions who have registered
their OpenURL Resolvers with the Router. It receives in the
regions of 100,000 requests per day for routing.
From Deo statistics by email
 It is truly indeed a popular piece of middleware,Even
though there are less than 10 OpenUrl linking resolvers
running in China

30. Background

31. ScienceChina (SC) - Introduction
SC is a service system of Chinese science and
technology literature
SC is the Web-based platform that integrate
Web-
current core chinese journal articles ,references
and relationships based on cited behavior.
Additionally, SC provide a link resolver services
SC was built in 2002,by the library of CAS, part
of National Science Digital Library Project
(CSDL)

32. ScienceChina – SubDatabase
SC consists of ：
Chinese Science Citation Database（CSCD）
CSCD Essential Science Indicators （CSCD-ESI）
CSCD Journal Citation Reports （CSCD-JCR）
Chinese Science Document Database（CSDD）
CSCD CSCD-ESI
CSDD CSCD-JCR

33. Chinese Science Citation Database (CSCD)
The CSCD provides seamless access to current
and retrospective multidisciplinary information from
approximate 1000 of the most prestigious research
journals in China
 CSCD also provides a unique search method--
method--
cited reference searching. With it, users can
navigate forward, backward, and through the
literature, searching all disciplines and time spans
to discover all the information relevant to their
research
