The image shown opposite is one page form Rudolf Zäch: Die neuzeitliche Küche. Wallisellen, 1931.
Like this one, many of the texts of the first half of the 20th century are published in Gothic type, a type especially younger readers sometimes have trouble to read. The digitisation of these texts makes them more accessible again.
After the acquisition of a text all relevant bibliographical data is entered into a database.
In many cases for digitisation the original book is cut into separate pages. These are scanned and prepared for OCR (optical character recognition).
The page shown here contains several challenges for digitisation, such as recognition of Gothic type and spaced out words. The processing of special text elements like marginal notes, enumerations and footnotes have to be defined.
