Digital Library Systems Group


To create digital information technology for the advancement of study, research and scholarly productivity, copyright law compliant technology that:

  • Maximizes utilization of scholarly library collections content by:
    • providing tools that substantially outperform search engines in identifying the most relevant content
    • removing technological inefficiencies from the research process (e.g. by providing instant access to relevant content with minimal user actions)
    • interconnecting thousands of library collections with advanced new technology
  • Supports scholarly researchers, authors and publishers in creating and delivering the highest quality content to the maximum number of researchers, students, scholars, and library patrons.


In 2004, DLSG sold its first KIC, BSCAN ILL, and Opus systems. Ten years later, nearly 70% of students at US universities were served by DLSG digitization systems (90% by budget), and public libraries were beginning to investigate and learn the value of DLSG technologies. Then, in 2015, DLSG began developing the Digital Library Ecosystem. After five years and over a quarter of a million R&D professional hours invested, the Digital Library Ecosystem is ready, just in time to serve the study and research challenges caused by social distancing.

The Roles of the Librarian in the Digital Age

In the Digital Age, libraries and librarians have new and essential responsibilities. Instant access to Web search results makes it all too easy to disregard more vetted sources of information. Unlike Web-based information, the $100+ billion libraries have invested in collection development over decades and centuries is immutable and [mostly] factual. If only one in ten citizens are informed by [largely] unbiased information, these people can share their findings with friends and family members, perhaps reducing disagreements in our society to just those topics that are actually arguable.

Give Your Researchers Instant Access to Billions of pages of Relevant Content

For Scholars and Researchers, HotLinks Research Tool provides a revolutionary search-match system that takes up to 100 pages of personal research as input and instantly matches it with billions of pages of scholarly content in the print collections of your library and the libraries of other Digital Stacks Project members. HotLinks instantly finds 100 matches representing the most relevant content from billions of pages. Researchers are able to find valuable content that they would never find with standard search systems.

HotLinks Research Tool results can be viewed as ‘sample’ pages from the entire volume that promote copyrighted content that might otherwise remain unknown.

For better compliance with the Fair Use section of copyright law, the library can enable the ability for researchers to purchase the full content.

It is the digital age and your students, faculty and researchers should be able to browse and search your print collections visually wherever they are, 24/7, using their phone, tablet or PC. Virtual reality technology is replacing traditional text-based systems everywhere and it’s time for libraries to join in.

KAT Stacks provides a virtuality reality browsing experience that matches the layout of your library’s print collections, aisle by aisle, shelf by shelf. It includes:

  • SIP2 integration with your ILS
  • Bulk import of MARC records and instant virtual stacks using on-line images of spines and covers, and computer generated graphical images
  • Digital Item checkout via DLSG’s controlled digital lending solution
  • Expanded shelf view that includes all books, including those in off-site storage, in reserves and in a high use section for digitizing excerpts
  • Integrated bibliographic search
  • Professors suggested reading lists
  • And more...

The Publishers’ Perspectives

Your publishers’ representatives are just doing their jobs when they extoll the merits of purchasing new digital licenses without any consideration for the value of your existing print collections. However, your publishers’ marketing departments have a different relationship with libraries.

While librarians rarely meet their marketing teams, libraries have always helped publishers market new titles. Amazon does a great job of promoting new books. However, libraries continue to play an essential role in promoting new books. Libraries showcase new books that they lend for free, which results in the books being promoted to fellow researchers, students, friends and family members, and these days, the majority of people opt to buy the books they like.

Four Steps to Dramatically Increase
The Value of Your Scholarly Print Collections
  • 1. Digitize-On-Demand for Frequently Accessed Items

    A single print item can be copied (an excerpt at a time) an unlimited number of times, which, along with high quality and low prices explain why KIC digitization systems are on a thousand college campuses across the US and Canada. Promote digitize-on-demand to your study and research patrons by creating a centrally located section of the stacks with your frequently accessed books and materials, with multiple self-serve digitize-on-demand stations nearby. The concentration of highly used materials will also concentrate patrons and create a collective energy that will increase the apparent value of your print collections. Ideally, your reference and reserves materials should also be nearby.

  • 2. Optimized Controlled Digital Lending (CDL)

    Libraries need DRM specifically for lending the content in their print collections:

    • Copyright law for libraries has been updated for the digital age, but remains substantially underutilized
    • The digital rights management (DRM) systems used by publishers are NOT ideal for lending

    DLSG offers extended CDL that addresses each element of DMCA Sections 107 and 108 and the ‘first use’ clause of DMCA Section 109, and that works with the thousands of KIC, Opus & BSCAN ILL digitization systems that are in use across the US and Canada. These systems range in price from just a few thousand dollars for a small system with a face-down BookEdge scanner, to nearly forty thousand dollars for a very large system with the new Bookeye 5 scanner, the fastest high quality scanner available today, with Click Mini scanners occupying the mid-range.

  • 3. KAT Stacks – Instant 24/7 Virtual Reality Browsing & Search

    It doesn’t take much to convince most librarians that KAT Stacks is valuable. The big question is: “How expensive and difficult is it to get?” It is actually quite easy to setup a computer generated (CGI) version of KAT Stacks that matches your print collections – simply bulk load your collections into KAT Stacks by importing your MARC records. CGI versions of the spines and covers of your items are automatically created. Then walk through your library with a WiFi-connected tablet, identifying each aisle and the first book on each shelf. KAT Stacks can also be informed which books are in special sections such as reserves and your new digitize-on-demand section, and which books have been moved to storage. When users are viewing a single shelf in KAT Stacks, they can switch to a mode that includes the books in storage and in special sections of the library – digital shelves have no width limits.

    To stay current as your collection changes, and to show the checkout status of each item, KAT Stacks integrates with your ILS via SIP2.

    For a very realistic and immersive virtual reality experience for the most important sections of your stacks, use the KIC Covers & Spines option to digitize up to 100 spines and covers per hour.

  • 4. HotLinks Research Tool – Beyond Search

    While it is certainly useful, catalog search is woefully inadequate for research and study - the catalog contains too little information to be truly effective. Even full text search has limitations: 1) a full-text search system should be tightly connected with the holdings of your library and your library’s ILS; 2) while studying, your student patrons should be able to instantly and easily access content from your print collections that closely matches the textbook chapters they are currently studying; and 3) your researchers should be able to instantly and easily find the hundred or so closest matches in your entire print collections and perhaps beyond, to the dozens or hundreds of pages of text that they have created on a particular research topic.

    HotLinks Research Tool allows students and researchers to find valuable scholarly books that they would never otherwise encounter. When used as high-speed study & research input machines, KIC digitization systems allow students to capture full textbook chapters, and allow researchers to capture and combine large amounts of printed and digital text, in just a few minutes, then output the content to MyDocs(a free study/research app for phones, tablets & PCs), along with metadata that characterizes all pages of input for HotLinks Research Tool. While studying or researching, the user selects an anchor term (a search term), invokes HotLinks Research Tool, and is instantly able to swipe or scroll through the 100 or so best matches to the entire chapter or research text that also contains the anchor term.

    Together, DLSG’s Digitize-on-demand KIC systems, MyDocs with KIC Study System and optimized CDL, KAT Stacks and HotLinks Research Tool reinvent the library in the digital age. DLSG has a name for this entire integrated transformation: the Digital Stacks Ecosystem. Perhaps it’s time to reinvent and renew partnerships between publishers and libraries.

KIC Self-serve Digitization Kiosks (digitize for Controlled Digital Lending / DRM)

KIC Self-Serve Digitize-on-Demand Kiosks

With KIC, thousands of students and researchers can make copies of each item in your print collections, (an excerpt at a time). This and its high quality and low prices have explain why KIC digitization systems are on a thousand college campuses across the US and Canada.

In addition to supporting new high-speed whole book digitization options that allow the thousands of existing KIC systems in US and Canadian academic and research libraries to digitiz features, KIC systems provide powerful digital age services such as the ability to reorganize study and research materials, semi-automatically and automatically create and add citations, and order printed books.

Promote digitize-on-demand to your study and research patrons by creating a centrally located section of the stacks with your frequently accessed books and materials, with multiple selfe-serve digitize-on-demand stations nearby. The concentration of highly used materials will also concentrate patrons and create a collective energy that will increase the apparent value of your print collections. For even greater value, place your reference and reserves materials nearby.
