  12. 1.4 Software (cont.) • Illiad server (Inter-library Loan) • Taiwan Newspaper database • Chinese Database Server: Sibucongkan (四部叢刊); Sikuquanshu (四庫全書); ekangxi dictionary (康熙字典)

  13. 1.5 HKUL DL initiatives

  14. 1.5 HKUL DL initiatives Imaging database

  15. 1.5 HKUL DL initiatives • 1.5.1. Digitalization projects e.g. ExamBase • First in-house developed database • Imaging database for past exam. papers • Released in 1996 • Use DMS, client-server model • Shifted to web-based soon • tiff only (on-the-fly convert to gif/jpg) , no PDF!!!

  16. Hardware High-speed flat bed scanner (36ppm) Software Kofax capture 3.0 Sophisticated software includes scanning, OCR, verifications.

  17. Logistics Scanning Automatic indexing Verification and manual inputting Data Publishing Publish data to Oracle database

  18. Scanning • Papers are scanned in batch mode (~200 pages per batch) • Uses separation sheet to separate different documents(The separation sheet is printed with barcoded index (e.g. department, course code) and fixed-sized font textThe separation sheets can be re-used.)

  19. Automatic indexing • To recognize those barcoded indexes and text printed on the separation sheet • Verification and manual inputting • No need to verify the barcoded indexes, as the accuracy is > 99.999% • In-doubt OCRed text is marked in red, it is easy to verify • Input other indexes manually (e.g. exam. date)

  20. 1.5 HKUL DL initiatives(cont.) • e.g. Newspaper clippings • Full-text imaging database • Outsource: scanning/indexing/OCR • Oracle context cartridge as full-text search engine (supports no Chinese!) • Decision: keep on using? or buying a 3-rd party full-text software??

  21. 1.5 HKUL DL initiatives(cont.) • 1.5.2 Value-added Bibliographic databases • Subset of library catalogue • e.g. TOC , Thesis Online, AV materials.. • Debate: • single point source or a number of subsets??

  22. 1.5 HKUL DL initiatives(cont.) e.g. Table of Contents • To automate the inputting of TOC into bibliographic records

  23. Hardware Overhead book scanner (~4sec per image) Software Kofax capture 3.0 Sophisticated software includes scanning, OCR, verifications.

  24. Techniques Scanning Chinese OCR Proofreading Data Publishing Publish data to Catalogue

  25. Scanning Use book scanner to scan the book’s TOC benefits: no need to flip the book for scanning can scan two sides at one time increase the speed of scanning Chinese OCR A plug-in module was written to interface with Kofax Capture for Chinese OCR (TH-OCR 7.5)

  26. Proofreading Use MS Word (Chinese) to do the proofreading Macro program was written to ease the step of assigning MARC sub-fields Publish data to Catalogue Done at night in batch mode Use tcl/tk expect script to automate the upload process

  27. 1.5 HKUL DL initiatives(cont.) • 1.5.3 Subject-based e-resources • Redesign tag 996 • A number of useful information on e-resources • Grouping of materials by subject: fulfill users’ needs • Ease of extending our further DL projects (e.g. portal) • See HKUL HP (databases, EJ, Ebooks & ENews) • 1.5.4 Internet resources • 1.5.5 Electronic Delivery (ILLiad)

  28. 1.5 HKUL DL initiatives(cont.) • 1.5.6 Virtual services • E-forms (e.g. BRO) • Online reference • 1.5.7 Automation • Increase efficiency • e.g. amend thousand of records in batch • Electronic submission • Staff intranet • Innoface

  29. 1.5 HKUL DL initiatives(cont.) • 1.5.8 Collaboration • Union catalogue w/ Jinan University • 1.5.9 Authentication : Proxy, ezproxy, IP control • 1.5.10 Others…: for accessing legacy CDROM databases

  30. 2. Going to do… • Storage Area Network (SAN) • Abundance of servers • One-stop search • Alert service • Wireless applications

  31. 2.1 SAN Problem a: Storage • large data size of our hosted databases • high monthly data increase rate • Databases are hosted in different hosts/OS

  32. 2.1 SAN (cont.) Problem b: Backup • backup drive for every machine • backup software license for every machine • Need to handle a lot of backup tapes

  33. 2.1 SAN (cont.) Solution –(SAN) • Put all data storage into a single large-sized expandable storage device. • The storage device is connected to the hosts by high-speed Fiber channels • Fiber channel loop is used to connect to each host in order to ensure highavailability • Backup can be done on a single device

  34. 2.2 Abundance of servers Problem : • Hard to monitor the status and activities of each server • Waste time to tune the performance of each server

  35. 2.2 Abundance of servers (cont.) Solution –Server consolidation • Buy several powerful servers instead of many cheap mid-range servers • Keep as minimal servers as possible • Save space and UPS power ratings , i.e. $$ saving • Save man power to administer/maintain server performance , i.e. cost saving

  36. 2.3 One-stop search • Before searching, one needs to know which database suit one’s need • To search multiple databases simultaneously • e.g. OAI (http://www.openarchives.org/ ) • e.g. CDL SearchLight (http://www.cdlib.org/cgi-bin/searchlight)

  37. 2.4 Alert service • To alert users for new information • SDI 2.5 Wireless Application • A study on mobile and PDA application in Library

  38. 3. Challenges • Changes • New Technologies • Competitors • What are the (future) standards? • Contents • Digital Vs printed • Information overflow • Lifelong education

  39. 3.1 The causes of changes • Development of I.T. • Network, telecommunications, digitalization, storage format, access model, … • Economy • Online, e-commerce, smart card , … • Learning environment • Life-long learning • Mode of communication • Email, ICQ

  40. 3.2 New technologies • Changing … so fast • Acronyms • Help: http://www.webopedia.com • Who knows what the future would be? • Reluctant to change • Don’t be afraid to dig in • See : Editor’s notes, Computers in Libraries, vol.22, no.8, p.6

  41. 3.3 Competitors • Who? • See: OCLC White paper on the Information Habits of College Students (http://www2.oclc.org/oclc/pdf/printondemand/informationhabits.pdf) • 79% use a search engine for every or most searches!!

  42. Technology Adoption Life Cycle Late Majority Early Majority Early Adopters Laggards Innovators Source: Crossing the Chasm, Geoffrey Moore

  43. Crystal Ball?? • Number of visits  • Usage of physical materials  • Training to users & real-time support  • Demand for subject knowledge  • Competitors  • Fast services & high productivity • Information provider and producer • Cost-effectiveness • Library workflow goes to e-business model • Partnership • Provide services that lead to income

  44. 4. Overcome the challenges • What business are we in? • What are our major strengths & weakness? • Who are our competitors? • Who are our customers? their needs? • What factors are affecting Library? • Do we have the skills?

  45. 4. Overcome the challenges – how? • Training - to keep abreast with new technologies • Human resources - partners • Value-added services • User-oriented mindset • Automation • Improve the social image of librarians • Co-operation • Talk with other people in order to understand the technology different areas • Research

  46. 4. Overcome the challenges (cont.) • Skills? • Librarianship & IT knowledge • Teamwork, Commitment • Thinking methodology – creativity, use of knowledge • Outlook of the world • Interpersonal skills • Health!!

  47. Principles for building DL • Expect change • Know your content • Involve the right people • Design usable system • Ensure open access • Beware of data rights • Automate whenever possible • Adopt and adhere to standards • Ensure quality • Be concerned about persistence McCray, A. & Gallagher, M. (2001). Principles for Digital Library Development, Communications of the ACM, 44(5), pp.49-54.
