This paper examines digital archiving policies of open access (OA) electronic scholarly journals in Central Europe. The research sample consists of 1589 journals from nine Central European countries registered in the Directory of Open Access Journals (DOAJ). Results show that of the 1589 journals, 69% of them have an archiving policy. In terms of the number of indexed journals, Poland ranks first with 592 journals. Switzerland is at the forefront of digital archiving with 89% of archived journals. It was also found that Portico and national libraries are the most widely used archives, and that 19% of the preserved journals are archived in more than one archive. A preliminary analysis was also conducted to investigate the possible existence of a relationship between journal rank and digital archiving. The results show a higher number of JCR indexed titles, as well as a higher ranking, among archived journals. The paper also compares the status of archiving policies among Asian and Central European countries. The results reveal that archived journals are significantly more represented in Central European countries. [ABSTRACT FROM AUTHOR]

Purpose: The short lifespan of digital signatures presents a challenge to the long-term preservation of digitally signed records. It can undermine attempts to presume, verify or assess their authenticity. This paper aims to investigate the challenges of the expiration of digital signatures in the context of digital archiving. Design/methodology/approach: The paper identifies requirements for the long-term preservation of digitally signed records and compares them with the existing approaches. The characteristics, operational procedures and requirements of the technologies used for digital signatures are combined with the archival requirements to design a new model. Findings: The paper proposes a new model of a blockchain-based system, which can be combined with any digital archive to assist the process of long-term preservation of digitally signed records. Practical implications: The proposed model offers a new alternative to the current practice in the long-term preservation of digitally signed records, such as periodic resigning procedures or periodic wrapping of digitally signed records with archival timestamps. Originality/value: The proposed TrustChain 2.0 model is based on previous research conducted as part of the InterPARES Trust project. It builds on TrustChain 1.0 by including digital signature certificate chain validity information in a blockchain thus avoiding the issues concerning records confidentiality and privacy information disclosure. The paper contributes not only to the development of archival science but also shows archival institutions on how to approach long-term preservation of digitally signed records.

Purpose: The authors investigate optical character recognition (OCR) technology and discuss its implementation in the context of digitisation of archival materials. Design/methodology/approach: The typewritten transcripts of the Croatian Writers' Society from the mid-60s of the 20th century are used as the test data. The optimal digitisation setup is investigated in order to obtain the best OCR results. This was done by using the sample of 123 pages digitised at different resolution settings and binarisation levels. Findings: A series of tests showed that different settings produce significantly different results. The best OCR accuracy achieved at the test sample of the typewritten documents was 95.02%. The results show that the resolution is significantly more important than binarisation pre-processing procedure for achieving better OCR results. Originality/value: Based on the research results, the authors give recommendations for achieving optimal digitisation process setup with the aim of increasing the quality of OCR results. Finally, the authors put the research results in the context of digitisation of cultural heritage in general and discuss further investigation possibilities. [ABSTRACT FROM AUTHOR]

Archives, both analogue and digital, are primarily concerned with preserving records as originals. Because of this, immutable data as used in a blockchain data structure seem a logical choice when designing such systems. At the same time, archives maintain records which may need to change over the long term. It is a requirement of archival preservation to be able to update records' metadata in order not only to guarantee authenticity after digital preservation actions but also to ensure that relationships to other records, which might be created after an original record has entered the archive (and has been registered in a blockchain), can be maintained. The need to maintain an archival bond, which represents a network of relationships between aggregation of records, i.e., the relationship connecting previous and subsequent records belonging to the same activity, is a prime example of this requirement. This paper explores realisation of the archival bond in the context of blockchain-based archival system by proposing a supporting database system which enables metadata to be changed as required but also significantly simplifies searching compared to searching on-chain information, while keeping the immutability characteristic of blockchain.
