Helping to Justify Academic Library Budgets Since 2004

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.

It’s official – Judge Koeltl ruled against simple CDL

Content Strategies

It’s official – Judge Koeltl has ruled that simple CDL is illegal, on two counts – it is not transformative and it can substantially negatively impact authors and publishers, in violation of ©-Law Section 107 bullet four. DLSG suggests three strategies for substantially improving the quantity and usefulness of content accessed by academic library patrons: 1) TARGET 10% for ©-Law Section 108 access to content; and/or 2) Give your patrons access to HotLinks revolutionary new 2D full-text SearchMATCHTM with Personal Digital Mind Palace and Collaboration System; and/or 3) use DLSG’s CDL+ with all of its ©-Law Section 107, 108 and 109 compliance features that include the two ©-Law issues cited in Judge Koeltl’s ruling against simple CDL. DLSG’s CDL+ addresses both of these major issues: 1) DLSG’s CDL+ has controls to restrict its use sufficiently to ensure that it does not violate ©-Law Section 107 bullet four; and 2) CDL+ is highly transformative. CDL+ is integrated into DLSG’s Digital Stacks Ecosystem, which includes our revolutionary new HotLinks 2D full-text SearchMATCHTM discovery system with Personal Digital Mind Palace. In addition, DLSG’s Digital Stacks Ecosystem supports subscription-based content. DLSG’s CDL+ is Highly Transformative. more… DLSG’s CDL+ supports ©-Law Section 107 bullet 4. more… DLSG’s Digital Fence Technology. more… DLSG supports subscription-based content. more…

DLSG’s Digital Fence is unlike Other Section 109© Implementations … it allows patrons to digitally access all print collections content on their personal notebooks, tablets and phones while patrons are in the library. And DLSG’s Digital Fence is fully integrated with HotLinks 2D Full-text SearchMATCH Discovery and Personal Digital Mind Palace.

KIC Self-serve Digitization Kiosks

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 digitize up to four whole books per hour with bookmarks and other ADA features, KIC systems provide powerful digital age services such as the ability to reorganize study and research materials, semi-automatically and automatically add citations, and order printed books.

The Digital Stacks Ecosystem with Controlled Digital Lending (DRM)

HotLinks Research & Study Tools provide compelling reasons to digitize and KAT Stacks’ virtual reality browsing facility offers 24/7 virtual access to your stacks. Thousands of existing KIC systems in academic and research libraries across the US and Canada support newly released high-speed whole book digitization options that allow up to four whole books to be digitized in an hour with bookmarks and other ADA features. New, highly transformative Controlled Digital Lending (CDL) technologies for local and interlibrary lending interconnect digitized library print collections in ways never before thought possible, allowing thousands of libraries to share in the digitization effort, reducing the cost to about 1% of existing academic and research library budgets.

KIC Study System - Part of MyDocs with Controlled Digital Lending (DRM)

KIC Study System dramatically improves study efficiency and effectiveness with 9 study tools and methods, including ReadAlong Audio, computer-assisted skim/review, custom flashcards, study progress monitoring, instant access to Open Educational Resources and scholarly content via HotLinks Research & Study Tools.
