  • Adaptation: the Continuing Evolution of the New York Public
           Library’s Digital Design System

    • Authors: Jennifer L. Anderson & Edwin Guzman
      Abstract: A design system is crucial for sustaining both the continuity and the advancement of a website's design. But it's hard to create such a system when content, technology, and staff are constantly changing. This is the situation faced by the Digital team at the New York Public Library. When those are the conditions of the problem, the design system needs to be modular, distributed, and standardized, so that it can withstand constant change and provide a reliable foundation. NYPL's design system has gone through three major iterations, each a step towards the best way to manage design principles across an abundance of heterogeneous content and many contributors who brought different skills to the team and department at different times. Starting from an abstracted framework that provided a template for future systems, then a specific component system for a new project, and finally a system of interoperable components and layouts, NYPL's Digital team continues to grow and adapt its digital design resource.

  • Getting More out of MARC with Primo: Strategies for Display, Search and

    • Authors: Kelley McGrath; Lesley Lowery
      Abstract: Going beyond author, title, subject and notes, there are many new (or newly-revitalized) fields and subfields in the MARC 21 format that support more structured data and could be beneficial to users if exposed in a discovery interface. In this article, we describe how the Orbis Cascade Alliance has implemented display, search and faceting for several of these fields and subfields in our Primo discovery interface. We discuss problems and challenges we encountered, both Primo-specific and those that would apply in any search interface.

  • Extending and Adapting Metadata Audit Tools for Mountain West Digital
           Library Members

    • Authors: Teresa K. Hebron
      Abstract: As a DPLA regional service hub, Mountain West Digital Library harvests metadata from 16 member repositories representing over 70 partners throughout the Western US and hosts over 950,000 records in its portal. The collections harvested range in size from a handful of records to many thousands, presenting both quality control and efficiency issues. To assist members in auditing records for metadata required by the MWDL Metadata Application Profile before harvesting, MWDL hosts a metadata auditing tool adapted from North Carolina Digital Heritage Center’s original DPLA OAI Aggregation Tools project, available on GitHub. The tool uses XSL tests of the OAI-PMH stream from a repository to check conformance of incoming data with the MWDL Metadata Application Profile. Use of the tool enables student workers and non-professionals to perform large-scale metadata auditing even if they have no prior knowledge of application profiles or metadata auditing workflows.In the spring of 2018, we further adapted and extended this tool to audit collections coming from a new member, Oregon Digital. The OAI-PMH provision from Oregon Digital’s Samvera repository is configured differently than that of the CONTENTdm repositories used by existing MWDL members, requiring adaptation of the tool. We also extended the tool by adding the Dublin Core Facet Viewer, which gives the ability to view and analyze values used in both required and recommended fields by frequency.Use of this tool enhances metadata completeness, correctness, and consistency. This article will discuss the technical challenges of project, offer code samples, and offer ideas for further updates.

  • Copyright and access restrictions–providing access to the digital

    • Authors: Saskia van Bergen; Lucas van Schaik
      Abstract: To provide access to the digitized collections without breaking any copyright laws, Leiden University Library built a copyright module for their Islandora-based repository. The project was not just about building a technical solution, but also addressed policy, metadata, and workflows. A fine-grained system of access rights was set up, distinguishing conditions based on metadata, IP address, authentication and user role.

  • Using XML Schema with Embedded Schematron Rules for MODS Quality Control
           in a Digital Repository

    • Authors: Lisa Lorenzo
      Abstract: The Michigan State University Libraries Digital Repository relies primarily on MODS descriptive metadata to convey meaning to users and to improve discoverability and access to the libraries’ unique information resources. Because the repository relies on this metadata for so much of its functionality, it’s important that records are of consistently high quality. While creating a metadata guidelines document was an important step in assuring higher-quality metadata, the volume of MODS records made it impossible to evaluate metadata quality without some form of automated quality assessment. After considering several possible tools, an XML Schema with embedded Schematron rules was ultimately chosen for its customizability and capabilities. The two tools complement each other well: XML Schemas provide a concise method of dictating the structure of XML documents and Schematron adds more robust capabilities for writing detailed rules and checking the content of XML elements and attributes. By adding the use of this Schema to our metadata creation workflow, we’re able to catch and correct errors before metadata is entered into the repository.

  • Are we still working on this' A meta-retrospective of a digital
           repository migration in the form of a classic Greek Tragedy (in extreme
           violation of Aristotelian Unity of Time)

    • Authors: Steve Van Tuyl; Josh Gum, Margaret Mellinger, Gregorio Luis Ramirez, Brandon Straley, Ryan Wick, Hui Zhang
      Abstract: In this paper we present a retrospective of a 2.5 year project to migrate a major digital repository system from one open source software platform to another. After more than a decade on DSpace, Oregon State University’s institutional repository was in dire need of a variety of new functionalities. For reasons described in the paper, we deemed it appropriate to migrate our repository to a Samvera platform. The project faced many of the challenges one would expect (slipping deadlines, messy metadata) and many that one might hope never to experience (exceptional amounts of turnover and uncertainty in personnel, software, and community). We talk through our experiences working through the three major phases of this project, using the structure of the Greek Tragedy as a way to reflect (with Stasimon) on these three phases (Episode). We then conclude the paper with the Exodus, wherein we speak at a high level of the lessons learned in the project including Patience, Process, and Perseverance, and why these are key to technical projects broadly. We hope our migration story will be helpful to developers and repository managers as a map of development hurdles and an aspiration of success.

  • Spinning Communication to Get People Excited About Technological Change

    • Authors: Suzanna Conrad
      Abstract: Many organizations struggle with technological change. Often, the challenges faced are due to fear of change from stakeholders within the institution. Users grow accustomed to certain user interfaces, to processes associated with a specific system, and they can be frustrated when they have to revisit how they interact with a system, especially one that they use on a daily basis. This article will discuss how to acknowledge the fears associated with technological change and will suggest communication tactics and strategies to ease transitions. Specific scenarios and examples from the author’s experiences will be included.

  • Machine Learning and the Library or: How I Learned to Stop Worrying and
           Love My Robot Overlords

    • Authors: Harper; Charlie
      Abstract: Machine learning algorithms and technologies are becoming a regular part of daily life - including life in the libraries. Through this article, I hope to:* To introduce the reader to the basic terminology and concepts of machine learning* To make the reader consider the potential ethical and privacy issues that libraries will face as machine learning permeates society* To demonstrate hypothetical possibilities for applying machine learning to circulation and collections data using TensorFlow/Keras and open datasetsThrough these goals, it is my hope that this article will inspire a larger, ongoing conversation about the utility and dangers of machine learning in the library (and concurrently society as a whole). In addition, the tripartite division of the article is meant to make the material accessible to readers with different levels of technical proficiency. In approaching the first two goals, the discussion is focused on high level terms and concepts, and it includes specific public cases of machine learning (ab)use that are of broad interest. For the third goal, the discussion becomes more technical and is geared towards those interested in exploring practical machine learning applications in the library.

  • Assessing the Potential Use of High Efficiency Video Coding (HEVC) and
           High Efficiency Image File Format (HEIF) in Archival Still Images

    • Authors: Michael J. Bennett
      Abstract: Both HEVC (ISO/IEC 23008–2) video compression and the HEIF (ISO/IEC 23008-12) wrapper format are relatively new and evolving standards. Though attention has been given to their recent adoption as a JPEG replacement for more efficient local still image use on consumer electronic devices, the standards are written to encompass far broader potential application. This study examines current HEVC and HEIF tools, and the standards’ possible value in the context of digital still image archiving in cultural heritage repositories.

  • The Tools We Don’t Have: Future and Current Inventory Management in
           a Room Reservation System

    • Authors: Denis Galvin; Mang Sun, Hanjun Lee
      Abstract: Fondren Library at Rice University has numerous study rooms which are very popular with students. Study rooms, and equipment, have future inventory needs which require a visual calendar for reservation. Traditionally libraries’ manage reservations through a booking module in an Integrated Library System (ILS), but most, if not all, booking modules lack a visual calendar which allows patrons to pick out a place and time to create a reservation. The IT department at Fondren library was able to overcome this limitation by modifying the open source Booked Scheduling software so that it did all of the front end work for the ILS, while still allowing the ILS to manage the use of the rooms.

  • WMS, APIs and LibGuides: Building a Better Database A-Z List

    • Authors: Veronica Ramshaw; Véronique Lecat Thomas Hodge
      Abstract: At the American University of Sharjah, our Databases by title and by subject pages are the 3rd and 4th most visited pages on our website. When we changed our ILS from Millennium to OCLC’s WorldShare Management Services (WMS), our previous automations which kept our Databases A-Z pages up-to-date were no longer usable and needed to be replaced. Using APIs, a Perl script, and LibGuides’ database management interface, we developed a workflow that pulls database metadata from WMS Collection Manager into a clean public-facing A-Z list. This article will discuss the details of how this process works, the advantages it provides, and the continuing issues we are facing.

  • Editorial: Beyond Posters: On Hospitality in Libtech

    • Authors: Ruth Kitchin Tillman
      Abstract: In this editorial, I will be using the word hospitality to mean the intentional welcome of others into a space which one currently occupies, possibly as a member of a dominant group. I do not wish to encourage the idea that one should cultivate or maintain a role of benevolent host in a way that forces others to remain forever guest or outsider, although there will always be newcomers. Hospitality may be a first step to ceding one's position as host in a space. It may be expanding that space to become a place with many potential hosts, each respected for their varied contributions and skillsets. It may also be supporting those in a different space or a different role, such as those who use the technologies we build and support (both colleagues and patrons), and respecting them in that space.

  • What’s in a Name' On ‘Meaningfulness’ and Best Practices in
           Filenaming within the LAM Community

    • Authors: Drew Krewer; Mary Wahl
      Abstract: Cultural institutions such as libraries, archives and museums (LAM) face many challenges with managing digital collections, particularly when it comes to organizing the individual files that make up each collection. While tools such as metadata and collection management systems support identification and arrangement for digital files, administrative control depends significantly on the mere filenaming in use beneath the surface. Anecdotal evidence has shown that many LAM institutions have specialized filenaming schemes in place for their digital collections. This paper includes a literature review of filenaming practices in the LAM community, followed by a description and analysis of survey data regarding filenaming practices in the LAM community. The purpose of the survey was to learn about filenaming conventions in use within LAM organizations who have filenaming policies in place. The data suggests that: similarities and differences exist in filenaming approaches between museums/galleries, archives/special collections, and academic institutions; it is preferred that filenaming be simultaneously meaningful to both humans and computers; and conventions that affect sortability are deemed more important than those that affect readability. The data also indicate several subtopics related to filenaming that would benefit from further study.

  • Centralized Accessioning Support for Born Digital Archives

    • Authors: Alice Sara Prael
      Abstract: Archives often receive obsolete digital storage media alongside paper acquisitions: CDs and DVDs mixed in with folders of correspondence, Zip disks, and floppy disks set aside by the donor with the intention to review the content later. Archives must not only have the expertise to work with digital media, but also the hardware and software to capture the content without the risk of altering the files merely by viewing them. This article will describe how Yale University Libraries and Museums addressed accessioning of born-digital archival content on physical media through a centralized digital accessioning support service. Centralizing the hardware and expertise required for working with physical media made it possible to accession media more quickly and return the files to the originating archives for arrangement and description.

  • Wikidata: a platform for your library’s linked open data

    • Authors: Stacy Allison-Cassin; Dan Scott
      Abstract: Seized with the desire to improve the visibility of Canadian music in the world, a ragtag band of librarians led by Stacy Allison-Cassin set out to host Wikipedia edit-a-thons in the style of Art+Feminism, but with a focus on addressing Canadian music instead. Along the way, they recognized that Wikidata offered a low-barrier, high-result method of making that data not only visible but reusable as linked open data, and consequently incorporated Wikidata into their edit-a-thons. This is their story.

  • Redux: Tabulating Transactions with Raspberry Pi and Visualizing Results

    • Authors: Tim Ribaric
      Abstract: Often in the library tech world we are not given the opportunity to attempt a project again. Effort spent re-doing a previous project in a different way, in some sense, means wasting time that could be used to work on new initiatives. This article describes a redux of a project, a revenge story so to speak. In 2013 the Arduino based Tabulatron first entered production at Brock University Library. The device had its flaws, an attempt to rectify those flaws was manifested in the creation of the PiTab, the story of which is presented here.

  • FAIR Principles for Library, Archive and Museum Collections: A proposal
           for standards for reusable collections

    • Authors: Lukas Koster; Saskia Woutersen-Windhouwer
      Abstract: Many heritage institutions would like their collections to be open and reusable but fail to achieve that situation because of organizational, legal and technological barriers. A set of guidelines and best practices is proposed to facilitate the process of making heritage collections reusable. These guidelines are based on the FAIR Principles for scholarly output (FAIR data principles [2014]), taking into account a number of other recent initiatives for making data findable, accessible, interoperable and reusable. The resulting FAIR Principles for Heritage Library, Archive and Museum Collections focus on three levels: objects, metadata and metadata records. Clarifications and examples of these proposed principles are presented, as well as recommendations for the assessment of current situations and implementations of the principles.

  • Approaching the largest ‘API’: extracting information from the
           Internet with Python

    • Authors: Jonathan E. Germann
      Abstract: This article explores the need for libraries to algorithmically access and manipulate the world’s largest API: the Internet. The billions of pages on the ‘Internet API’ (HTTP, HTML, CSS, XPath, DOM, etc.) are easily accessible and manipulable. Libraries can assist in creating meaning through the datafication of information on the world wide web. Because most information is created for human consumption, some programming is required for automated extraction. Python is an easy-to-learn programming language with extensive packages and community support for web page automation. Four packages (Urllib, Selenium, BeautifulSoup, Scrapy) in Python can automate almost any web page for all sized projects. An example warrant data project is explained to illustrate how well Python packages can manipulate web pages to create meaning through assembling custom datasets.

  • Using R and the Tidyverse to Generate Library Usage Reports

    • Authors: Andy Meyer
      Abstract: Gathering, analyzing, and communicating library usage data provides a foundation for thoughtful assessment. However, the amount of time and expertise required creates a barrier to actually using this data. By using the statistical programming language R and the tools and approach of the Tidyverse, the process of gathering, analyzing, and communicating data can be automated in ways that reduce the amount of time and energy required. At the same time, this approach increases staff capacity for other data science projects and creates a shareable model and framework for other libraries. This article focuses on electronic resource usage reports - especially Counter DB1 Reports - but this approach could be extended to other data sources and needs.

  • Archidora: Integrating Archivematica and Islandora

    • Authors: Tim Hutchinson
      Abstract: “Archidora” is shorthand for the publicly available integration between the open source software packages Archivematica and Islandora. Sponsored by the University of Saskatchewan Library, this integration enables the automated ingest into Archivematica of objects created in Islandora. This will allow institutions that use Islandora as a digital asset management system, particularly for digitized material, to take advantage of Archivematica’s standards-based digital preservation functionality, without requiring staff doing digitization to interact with Archivematica. This paper outlines the basic functionality and workflow of archidora; provides an overview of the development process including challenges and lessons learned; and discusses related initiatives and possible future directions for development.

  • Microdata in the IR: A Low-Barrier Approach to Enhancing Discovery of
           Institutional Repository Materials in Google

    • Authors: Shayna Pekala
      Abstract: Georgetown University Library curates a multitude of open access resources in its institutional repository and digital collections portal, DigitalGeorgetown. Over the last several years, the Library has experimented with methods for making these items increasingly visible in search engine search results. This article describes the Library’s low-barrier approach to applying vocabulary to its DSpace institutional repository using microdata, as well as the challenges with and strategies used for assessing this work. The effects of the application of microdata to DigitalGeorgetown on Google search results were tracked over time using three different metrics, providing new insights about its impact.

  • Getting Real in the Library: A Case Study at the University of Florida

    • Authors: Samuel R. Putnam; Sara Russell Gonzalez
      Abstract: In the fall of 2014, the University of Florida (UF) Marston Science Library, in partnership with UF IT, opened a new computer lab for students to learn and develop mobile applications. The Mobile Application Development Environment (MADE@UF) features both software and circulating technology for students to use in an unstructured and minimally-staffed environment. As the technological landscape has shifted in the past few years, virtual and augmented reality have become more prominent and prevalent, signaled by companies like Facebook, Google, and Microsoft making significant financial investments in these technologies. During this evolution, MADE@UF has migrated to focus more on virtual and augmented reality, and we will discuss the opportunities and challenges that hosting and managing such a space has provided to the science library and its staff.

  • Accio e-Libri: Magically Delivering Digital Resources to Patrons Using NFC

    • Authors: Christopher M. Jimenez; Barbara M. Sorondo
      Abstract: To coincide with the 20th anniversary of the publication of Harry Potter and the Philosopher’s/Sorcerer’s Stone, our library created a Happee Birthdae Harry display incorporating Near Field Communication (NFC) technology alongside print materials in order to magically place electronic resources in our users’ hands. The display was a spellbinding success, increasing usage of both print and electronic items, and helping our students become familiar with this innovative technology in an engaging manner. This article will provide step-by-step instructions on the materials and procedures librarians need to implement NFC technology in their own libraries, and will discuss the challenges and opportunities associated with this rapidly spreading technology.

  • Ship It: Logistical tracking of ILL physical loans

    • Authors: Ryan Litsey & Scott Luker
      Abstract: The OBILLSK Shipment Tracking system is the first consolidated and comprehensive shipment information system for interlibrary loan. The system is unique because not only does it offer an interface for consolidating the items being shipped out of an ILL office, it also provides real time statistical data of global geographic shipping patterns, tracking of packages across all major couriers, and customized date range reporting for ILL shipment activity. This system takes advantage of several web-based technologies that makes it easy to use for students, staff and library administrators. The web-based software utilizes a .NET platform and SQL Server database. Client-side frameworks include Bootstrap and jQuery for responsive design, Shield UI for data visualizations, and jVectorMap for geographical representation of shipments. The system is now available for all libraries. It is actively in use at 15 academic libraries nationwide and has over 190,000 items scanned since October of 2016. It is through the development of innovative technologies that libraries can continue to serve as incubators for practical solutions that can help the discipline and practice of librarianship.
