Astronomical Catalogs - History First catalog by Hipparchos ( b.Chr.) 1022 stars (position and brightness) Continued by Ptolomäus and numerous astronomers into modern times Argelander ( ) all (northern) visible stars, a survey using a 10 cm telescope (22000 objects) variable stars Catalog by Messier ( ) nebulous objects not to be confused with comets (107 objects) Interactive Catalog Introduction Motivation AstroCat CVcat Demo Libraries

Astronomical Catalogs - Present Today: 6453 catalogs listed Strasbourg Astronomical Data Center Bibliographic data base with 4.6 M Smithsonian/NASA Astronomical Data Center Preprint Server, e.g. arXiv Several Virtual Telescope Projects, e.g. MAST (Multi Mission Archive at Space Telescope) Interactive Catalog Introduction Motivation AstroCat CVcat Demo Libraries

Connecting scientists and libraries Interesting aspects for librarians: –Long-term citation of dynamic web-pages change history / logfile Interactive Catalog Introduction Motivation AstroCat CVcat Demo Libraries

Connecting scientists and libraries Interesting aspects for librarians: –Collaborative work spaces –Supporting infrastructure for knowledge management and sense-making Adopt tools for other astronomic objects –Provide a portal Interactive Catalog Introduction Motivation AstroCat CVcat Demo Libraries

EZOOLO – Early Zoological Literature Online Provide free access for all scientists to the old zoological literature Literature is digitized in image format by the SUB Göttingen (Göttinger Digitization Centre) Collaborators have the right to enter data directly into the database Interactive Catalog Introduction Motivation AstroCat CVcat Demo Libraries

RMC – Rise of Modern Constitutionalism Create a scholarly edition of all constitutions that were part of the rising tide of modern constitutionalism between 1776 and 1849 Offering both digitized images and fulltext Supported by more than 30 contributors responsible for the constitutional documents within their regional and topical area of specialization Interactive Catalog Introduction Motivation AstroCat CVcat Demo Libraries

RMC – workflow Minimal standard in text editing: Microsoft Word Fully automated workflow: –M$ Word macro (incl. “submit button”) –Upload to RMC-Server and conversion into Open Office XML –XSLT-script to transform the text into TEI (Text Encoding Initiative), well defined, well structured, well tagged (indices) –Upload to web server Interactive Catalog Introduction Motivation AstroCat CVcat Demo Libraries
