  1. National Library of the Czech Republic as End-User of the Research Networks Adolf Knoll deputy director adolf.knoll@nkp.cz

  2. Characteristics • A lot of content for research • 6 million volumes • 9,000 manuscripts • 3,900 incunabula • 150,000 old printed books • Rare modern collections in several domains • Fully computerized • 155 Mbit/s connectivity to CESNET2 academic network (not member) • 100 Mbit/s between two main buildings • 100 Mbit/s LAN with 1 Gbit/s backbone between servers

  3. Data traffic: received • Access to large paid databases – mostly textual data • Normal web and e-mail traffic • Co-operation between libraries • Bibliographic records • Scanned articles for interlibrary loan Not critical from the point of view of external connectivity even if a lot of users (480 networked worstations for staff and users + servers, notebooks, etc. up to 560 units) • Web archiving activity (critical as to access speed for harvesting and storage space)

  4. Data traffic: produced and offered Bibliographic data • Large bibliographic databases (OPAC and Union Catalogue – millions of records, some of them may point to illustrative images of old prints or full text of articles from periodicals) • Scanned catalogues ca. 5 million records (TIFF files, several KB)

  5. Data produced and offered • Digitized content: • Ca. 1,000,000 million pages of periodicals (acid-paper) • Ca. 410,000 manuscripts in high quality • Ca. 130,000 pages printed books in lower quality • Production covering also collections of other institutions + archival storage + delivery

  6. Digitized contents • Typical files: • 1 – 2.6 MB JPEG periodicals • 1 MB access files for manuscripts, JPEG • Up to 8 MB access files for maps, MrSID • Robotic storage on magnetic tapes • Slow access, source of errors

  7. My friend used to say: Your HD is never big enough. vs. Your HD is always big enough. BOTH SENTENCES ARE TRUE

  8. PROVIDER Increasing network performance END-USER Increasing data processing Higher speed Grid computing Increasing traffic Thinner – but still acceptable - data files for the same objects Higher speed Grid computing How to pass through the bottleneck? INDIVIDUALS Academic-driven Public-driven

  9. Foreseen future • Implementation of large disk storage and access facilities • Production of optimized (smaller) access data files from the archival ones (optimized JPEG; wavelet compression, MRC-based formats as DjVu or LDF) • Separation of access systems from the archiving ones • More co-operation within the Czech Academic Network for storage and access reasons (web harvesting, large data files) to share technological resources • Will be implemented as far as we are able to secure necessary funding (higher connectivity, more flexible storage facilities, more sophisticated applications, more processing, …) • Sharing digital content in international co-operation (common gateways: historical research, musicology, digitized periodicals, …)
