Outline Interactive Catalog Introduction Motivation Astro. Cat CVcat Demo Libraries • • • Introduction Motivation Astro. Cat CVcat Demo Connecting scientists and libraries
Astronomical Catalogs - History Interactive Catalog Introduction Motivation Astro. Cat CVcat Demo Libraries • First catalog by Hipparchos (180 -125 b. Chr. ) 1022 stars (position and brightness) • Continued by Ptolomäus and numerous astronomers into modern times • Argelander (1799 -1875) all (northern) visible stars, a survey using a 10 cm telescope (22000 objects) variable stars • Catalog by Messier (1730 -1817) nebulous objects not to be confused with comets (107 objects)
Astronomical Catalogs - Present Interactive Catalog Introduction Motivation • Today: 6453 catalogs listed e. g. @ Strasbourg Astronomical Data Center Astro. Cat CVcat Demo Libraries • Bibliographic data base with 4. 6 M entries @ Smithsonian/NASA Astronomical Data Center • Preprint Server, e. g. astro-ph @ ar. Xiv • Several Virtual Telescope Projects, e. g. MAST (Multi Mission Archive at Space Telescope)
Motivation for interactive catalogs Interactive Catalog From data to paper Introduction Motivation Astro. Cat CVcat Demo Libraries • • Raw data Reduced data Derived quantities Publication Data Archive ? Bibliographic Archive
TRIPP
Current and Future Challenges Interactive Catalog • Dedicated survey telescopes Introduction Motivation Astro. Cat • Larger CCD cameras CVcat Demo Libraries • E. g. Pan-STARRS with few Tbytes/night
Motivation for interactive catalogs Interactive Catalog From paper to (meta-)data Introduction Motivation Astro. Cat CVcat Demo • Statistical analysis of available data • Planning of observations Libraries • Data base query of derived quantities
Requirements Interactive Catalog Introduction Motivation • Complete • Error free Astro. Cat CVcat Demo Libraries • Up to date • citable • Catalog from the community for the community Web based Interactive • Astro. Cat provides a platform for the implementation of such catalogs
Technical details Interactive Catalog Introduction Motivation Astro. Cat CVcat Demo Libraries • • Linux Postgre. SQL PHP 5 XML (Astro. Cat. ML)
The Team Interactive Catalog • Original Idea: Boris Gänsicke, Jens Kube (Institute for Astrophysics, Göttingen) Introduction Motivation Astro. Cat CVcat Demo Libraries • Movement towards a more general project in library context: Klaus Beuermann (IAG), Elmar Mittler (State and University Library Göttingen) • Design and definition: Fabian Euchner, Alexander Pollmer • Extended phase: Stefan Dreizler, Ralf Stockmann • Implementation CVcat: Fabian Euchner, Alexander Pollmer, Boris Gänsicke (now: Univ. of Warwick)
CVcat – a catalog of cataclysmic variables Pspin=833 sec

Connecting scientists and libraries Interactive Catalog Introduction Motivation • Interesting aspects for librarians: – Long-term citation of dynamic web-pages Astro. Cat CVcat Demo Libraries change history / logfile
Connecting scientists and libraries Interactive Catalog Introduction Motivation Astro. Cat CVcat Demo 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
EZOOLO – Early Zoological Literature Online Interactive Catalog Introduction Motivation Astro. Cat CVcat Demo Libraries • 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
RMC – Rise of Modern Constitutionalism Interactive Catalog Introduction Motivation Astro. Cat CVcat Demo Libraries • 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
RMC – workflow Interactive Catalog Introduction Motivation Astro. Cat CVcat Demo Libraries • 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
