Web archives are collections produced by libraries and other heritage institutions to permanently preserve online heritage. They often contain large amounts of material stored from the web through the use of web crawlers. From a usage perspective, they are often unpredictable, non-transparent and inconsistent data sources that contain numerous content gaps.
The basis for the analysis of scientific and similar monographs (academic books) in Slovenia in the period from 2013 to 2023 were bibliographic records in the COBIB.SI database that contain also information on the type of scientific publication (for less than half of the records verified). During this period, an average of 520 to 1245 monographs were published annually (depending on which types of works are counted as academic books and how reissues, such as reprints, new editions and e-books, are treated).
