The annual Joint Conference on Digital Libraries (JCDL) is the primary international event for the inter- and multi-disciplinary community of academics and practitioners in digital libraries coming from computer, information and social sciences, and other related disciplines. JCDL encompasses the many meanings of the term digital libraries, including notions of managing, operating, developing, curating, evaluating, or utilizing collections of data/information/knowledge in various domains.

In this global pandemic that put many of us into lockdown, quarantine, and separation for a long time, we will do our best to bring together communities and people again. As digital libraries are traditionally strong in connecting the digital and the physical world, we will pick up this heritage and establish a hybrid format that is as open as possible to everyone.

Topics of interest, as they relate to digital libraries, include, but are not limited to:

• Collaborative and participatory information environments
• Crowdsourcing and human computation
• Human-information Interaction
• Information visualization
• Social networks, virtual organizations and networked information
• Social media, community building, and applications
• User behavior and modeling

• AI / Machine Learning/ Data mining for DLs
• Dataset retrieval
• Information and knowledge systems
• Information retrieval
• Knowledge discovery
• Natural language processing
• Navigational and exploratory search
• Personalization and contextualization

• Digital archiving and preservation
• Digital humanities and heritage
• Knowledge organization systems in practice
• Personal digital information management
• Performance evaluation
• Policy and law
• Privacy and Intellectual property
• Scientific data management

• Data curation and stewardship
• Document genres
• Extracting semantics, entities, and patterns from large collections
• Infrastructure and service design
• Linked data and its applications
• Research data management
• Web and network science

JCDL 2022 will implement a variable paper length policy for research papers. There is no longer a distinction between long and short papers, nor a need of condensing or enlarging medium-length submissions. The maximum paper length is 10 pages in content plus unrestricted space for references. The minimum paper length is 4 pages in content plus unrestricted space for references. Any page length in between is allowed.

Paper length should be commensurate with contribution size and authors should submit a paper whose length reflects what is needed for the content of the work. The reviewers will assess whether the contribution is appropriate for the given length. Longer papers may be given more presentation time during the conference. We hope this new streamlined process will preserve the variety of paper lengths and foster the exchange of ideas without creating an artificial distinction among them. Reviewers will be explicitly advised to judge the quality of a paper and not its length.

• Late breaking results present new insights or information about research that was completed after the full paper submission deadline in January.
• Preliminary work are submissions that describe preliminary but novel ideas or results not previously published in other venues.
• Dataset submissions are a new category that allow description of research relevant datasets. These need to be either fully publicly-available or have to contain a publicly available subset.
• Demonstrations showcase innovative digital libraries technology and applications, allowing you to share your work directly with your colleagues in a high-visibility setting.

The presentation type of late breaking, preliminary work, dataset and demo submission will be decided during the reviewing process.

All submissions must be original works, not previously published or under review for publication elsewhere, in English, in PDF format, and in the current ACM two-column conference format. Suitable LaTeX, Word, and Overleaf templates are available from the ACM Website (use "sigconf" proceedings template for LaTeX and the Interim Template for Word).

All submissions will be rigorously peer-reviewed in a double-blind reviewing process. Submissions must be anonymous and all references to authors’ works have to be anonymised. Submissions are to be made via:

https://easychair.org/conferences/?conf=jcdl2022

All accepted papers will be included in the proceedings and will be presented at the conference. At least one author of each accepted paper is required to register for, and present the work at the conference at sight in Cologne. In case of travelling restrictions, authors will be enabled to present the work remotely.

Selected best papers will be invited for a special issue to be published with the International Journal on Digital Libraries (IJDL), Springer.
