Introduction

• Projects concerns are digitization of
• Mathematics-related books, thesis and manuscripts
• Mathematical journals
• Projects goals are
• Forming digital archives and databases
• Presenting digitized materials freely via
  Internet

3
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 Damjanovic, Aritmetika, Venice, 1767
• Jovan Doenovic, Cislenica, Budim, 1809
• Dimitrije Denic, 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 lInstitut 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

7
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

8
Technological aspects of the project (3)

• Types of metadata
• Descriptive
• obey librarian standards
• Structural
• Administrative
• resolution, rate of compression

9
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
