BatLit Bits and Pieces

Zotero is used for managing a collection of literature references. Versioned snapshots of this collection are securely packaged in a BatLit version. This version is then mobilized using a website, the Zenodo batlit community, and on offline storage media.

How Was Jorrit Able to Access Andersen, 1912?

Through Work of CETAF/GBatNet Eco-Interactions working group activities spanning 4.5 years in which:

  • goals were identified
    • (G1) make bat interaction data digitally accessible,
    • (G2) align bat taxonomic names to uncover their meaning, and
    • (G3) provide open-access to bat literature.
  • Plazi provided a legal framework via their Biodiversity Literature Repository 2.
  • BatBase 3 provided curatorial support.
  • Jorrit reused open source software 4 to track, package and version bat literature metadata and their pdfs.
  • Researchers like you shared their literature collections.

Next Steps

Further develop governance model to help sustain BatLit.

Improve BatLit depth, mobility, and access for the benefit of the bat research community.

Use BatLit as a digital foundation for associated projects.

Thank you / Acknowledgments

BatLit would not have been possible without the tremendous amount of work done by you, your fellow bat researchers, and those that proceeded us.

BatLit Workflow

BatLit Workflow

BatLit Workflow Steps

  1. Curator Adds Digital Copy to BatLit Project on Zotero 5
  2. Periodically, Archivist takes a snapshot of all Zotero records in BatLit, including bibliographic metadata and the “physical” digital copy (pdf).
  3. Archivist puts the snapshots in a signed digital archive (box) and signs the provenance logs
  4. Signed Digital Archive (or a batlit corpus version) is mobilized by translating and upload them to Zenodo, GitHub Pages, and various other network attached storage media
  5. Signed Digital Archives is stored on offline enabled media (sd card, external hard disk)
  6. Corpus is transmitted and discovered by students researchers
  7. Corpus is reused by students and researchers, enabling both manual (e.g., reading, annotation) and automated (e.g., raw material for language model training) workflows
  8. Reuse promotes improvement and further awareness

Accessing content associated with DOIs

Take 2.

  • turn on the internet (still there?)
  • open a web browser
  • load https://doi.org/10.5962/bhl.title.8322
    • and rely on a delicate and complex socio-technical network
  • inspect page
  • use mouse to click on a link that looks like a bug picture
  • download image and trust its authenticity

DOI Economics and Redirection

DOI Redirection Sequence Diagram

Internet Is Designed For Exchanging Information

The internet is a powerful tool for exchanging digital information. But the Internet’s contents changes constantly: websites are launched and taken down, webpages change, and content gets archived or lost.6

Internet Is Location-based

By design, a web address, or Uniform Resource Locator (URL), points to a specific internet location from which a resource, like a webpage, can be retrieved. However, a URL does not provide a way to verify that a retrieved webpage was the one we asked for. 7

Finding Content By Their Location Is … Tricky

Imagine using a URL-like reference to find a book at a library: instead of locating a book by what it is (e.g., title, author), you refer to a book by its location (e.g., third shelf on the second row next to the window). With this, a book becomes unfindable if moved to another shelf. And, if you do manage to find a book at the referenced location, how would you know you’ve found the book you are looking for? 8

Finding Content By Their (Summarized) Content Is … What Librarians Do

Instead of pointing to where books are located, librarians point to them using a bibliographic reference. For practical reasons, only a few identifying clues are included in such a reference (e.g., author, year of publication, title, and publisher). So, librarians refer to content by what it is, and knowing where it may be located is secondary. 9
