Digitization of mathematical editions in Serbia Žarko Mijajlović 1 Zoran Ognjanović 2 Aleksandar Pejović 3
Introduction Project’s concerns are digitization of: Mathematics-related books, thesis and manuscripts Mathematical journals Project’s goals are: Forming digital archives and databases Presenting digitized materials freely via Internet
Retro-digitization (1) Criteria for retro-digitization: Books and manuscripts selected for digitization should be related with mathematical sciences: mathematics, mechanics, astronomy, physics, mathematical geography etc Books considered for digitization had to be published before certain date in the past. We have chosen for this date the beginning of the Second World War (1941) Preference will be given to Serbian authors, or to written works related in some way to the area of Balkan
Retro-digitization (2) More than 100 books, thesis and manuscripts have been digitized: Vasilije Damjanović, Aritmetika, Venice, 1767 Jovan Došenović, Čislenica, Budim, 1809 Dimitrije Denić, Conforme abbildung des eliptishen paraboloids auf die ebene, Inaguaral dissertation der Philosoph. Fakultaet zu Jena, printed in Belgrade, 1885
Mathematical journals Retro-digitization started with: Publications de l’Institut Mathematique Publications of the Faculty of Electrical Engineering, Series Mathematics and Physics Today we have Internet presentation of freely accessible full-text mathematical journals
Technological aspects of the project (1) Addressed issues: Rules for choosing material to be digitized Information retrieval Metadata and rules for handling them Distribution of information using Internet Ability to search electronic files efficiently Proper choice of data format and resolution
Technological aspects of the project (2) Our retro-digitization process: Scanning document pages Gray-scale mode, 300 dpi Processing scanned pages Impurities cleaning, contrast improving Storing processed pages Tiff format, LZW compression Collecting processed pages PDF and/or DjVu
Technological aspects of the project (3) Types of metadata: Descriptive obey librarian standards Structural Administrative resolution, rate of compression
Technological aspects of the project (4) Used technologies: UTF-8 encoding MySQL database server JAVA PHP Apache web server
Conclusion Project is still a work in progress Future goals are: Unifying already digitized materials Adding new journals Continuing with retro-digitization Enlarging the database with journals from region
Digitized mathematical resources Virtual library of old mathematical works: eLibrary of mathematical journals: Retro-digitized journal Publications de l’Institut Mathmatique: Retro-digitized journal Publications of the Faculty of Electrical Engineering: Visual Mathematics:
