Kurt Munson Reflects on Project ReShare

Kurt Munson, Head of Access Services at Northwestern University, has been involved with Project ReShare since its inception.  He has served several important roles in the Project, including as a member of the Steering Committee and as Chair of the Product Management Team since 2018.  He was instrumental in the visioning of what Project ReShare could become, and he announced last month that he is stepping down from his official roles in Project ReShare. We want to celebrate his contributions and learn from his experience by interviewing him for the Project ReShare news site. 

Project ReShare: You’ve been involved with Project ReShare since the beginning.  Can you talk a little about how it all began?

Kurt Munson: Sebastian (Hammer,Co-Founder and President of Index Data) and I had a chat at the Midwinter meeting of the American Library Association in Denver [in 2018]. We were concerned about contraction and consolidation in the ILL software marketplace leaving libraries with fewer and fewer choices as well as a concern that standards for interoperability were being ignored. We got a group together for a first meeting in August of that year and started fleshing out what a product could be and, more importantly, how to have a community of support around it.

Project ReShare: What has changed since those early days?

Kurt Munson: ReShare has forced “churn in the market,” as I call it. ISO 18626 is now on all roadmaps due, I think, to our early adoption of that standard for ReShare. We have a growing community of users and a strong base of people committed to the project who graciously give their time to share knowledge to develop better products. 

Project ReShare: What are you most excited about for the future of ReShare?

Kurt Munson: Expansion both in functionalities and user base. The ability to build out a group of software functions to meet the needs of many different types of libraries as well as different groupings of libraries. More than anything else it’s the creativity of the community as it pushes the boundaries. ReShare has grown so much and my decision to step down is because the project is well past my ability to effectively support it with my knowledge and experience. In the words of Banksy- “When the time comes to leave, just walk away quietly and don’t make any fuss.”

In the end, I don’t know if Project ReShare benefited more from this experience or honestly that I did. It was a wonderful collaborative learning experience from which I have learned a great deal that I use daily.

Introducing Reservoir, the module behind ReShare’s Shared Inventory

Clara Fehrenbach spoke with Sebastian Hammer, Co-founder and President of Index Data, to learn more about Reservoir.

ReShare Shared Inventory

A shared inventory and consortial discovery has been a foundational piece of the Project ReShare vision since the beginning.  The 2021 ReShare Returnables launches at PALCI and ConnectNY went live with FOLIO’s Inventory module (dubbed “mod-inventory” in FOLIO-speak) as the basis for ReShare’s Shared Inventory storage, which in turn feeds into discovery layers, such as VuFind. Mod-inventory worked for its purpose, but it became clear that the way ReShare needs to ingest and use bibliographic data calls for a more flexible shared inventory infrastructure that is designed to ingest data from many different sources (i.e. individual member libraries in a consortium.)

Because ReShare was intended to be modular from the start, it was possible for Project ReShare and Index Data to be responsive to the needs of the community and update the infrastructure behind the Shared Inventory.

What is Reservoir?

Originally coined mod-meta-storage, Reservoir is the new underlying infrastructure of ReShare Shared Inventory.  Based primarily on PostgreSQL, Reservoir was envisioned and realized due to community need, both to address inefficiencies discovered in the live environments at PALCI and ConnectNY and to support the onboarding of IPLC onto ReShare Returnables using their Platform for Open Data (POD) infrastructure. Reservoir is designed to be both fast (quickly handling a very large number of records) and flexible (poised to reuse its contents for future purposes.)

In order to accomplish speed and flexibility, Reservoir does not merge records as they’re imported in the same way that mod-inventory was designed to do.  According to Sebastian, Reservoir works instead by “storing incoming bibliographic records separately and ‘clustering’ them using a match algorithm.” Then the records can be “merged” later for use in a consortial discovery layer or for other purposes. This method of clustering now, merging later was designed to allow much easier experimentation with different matching algorithms, since clusters can be reconfigured or rebuilt without needing a full data reload. It’s even possible to use more than one different matching algorithm at the same time with Reservoir.

Want to know how much faster Reservoir is?  Consider this: Using Reservoir, it takes less than a week to ingest, merge, and process a collection of about 80 million bibliographic records. Before Reservoir, it would have taken approximately five months to complete the same process.

Why “reservoir”?

A reservoir is “a large natural or artificial lake used as a source of water supply.”

Taking inspiration from “data lake” terminology and imagery, Reservoir was named because it is envisioned as a data lake that ingests data from sources “upstream” and provides a supply of “clean” data to any service positioned “downstream.”  Currently, the primary use of this data is in consortial discovery using VuFind, but it could be adapted for many different purposes, including consortial collection analysis.

News Release – MOBIUS to Implement ReShare Returnables for Resource Sharing

August 31, 2022

MOBIUS has announced that it will be implementing ReShare Returnables as its new resource sharing system, joining PALCI, ConnectNY, and the Ivy Plus Libraries Confederation who all have launched ReShare Returnables in recent months. The MOBIUS implementation will coincide with its launch of EBSCO FOLIO from EBSCO Information Services as its new library services platform. The MOBIUS migration, from Innovative’s INN-Reach and Sierra to ReShare Returnables and FOLIO, will begin in late 2022 with plans to be fully operational by the spring of 2024. Knowledge Integration will be leading the development of ReShare Returnables with MOBIUS.

Donna Bacon, Executive Director of MOBIUS, says that ReShare and FOLIO present an opportunity for MOBIUS members to move to open source resources with expert support. “Being part of an open-source community for our first library services platform is a significant move forward that will streamline processes, manage resources and leverage modern technologies,” Bacon noted. “We are eager to collaborate with the FOLIO and Project ReShare communities and hope to contribute to both projects’ future developments.” 

Knowledge Integration will partner with MOBIUS to develop features in ReShare Returnables that support direct consortial borrowing. Ian Ibbotson of Knowledge Integration, technical architect for Project ReShare, is keen to build on the relationship to expand the functionality with ReShare and promote interoperability with FOLIO.  “Being a small UK-based company with a solid commitment to developing open source solutions for libraries, we are excited by this partnership between Project ReShare, EBSCO, and MOBIUS,” Ibbotson said. “The leadership shown by MOBIUS in supporting the development of direct consortial borrowing functionality will benefit libraries worldwide and grow the wider resource-sharing capabilities of the project well beyond its traditional ILL roots.”

Project ReShare is a user-centered, community-owned resource sharing platform that will allow for the connection of disparate ILS platforms. MOBIUS has been an active, contributing member of the ReShare community since December of 2020. Adopting ReShare allows other libraries on disparate ILS systems to join MOBIUS. MOBIUS believes that ReShare offers more flexible opportunities to include a wider variety of platforms as the consortium continues to grow and evolve. 


Since its founding in July 1998, MOBIUS has transformed library services for the citizens of Missouri.  Formerly a part of the University of Missouri System, on July 1, 2010 MOBIUS became a Missouri not-for-profit corporation with 501 (C)(3) tax-exempt status.  Thanks to the hard work and dedication of its members, the organization has grown from 50 founding charter members to 80 members which include 64 academic libraries,11 public libraries, 4 special libraries, and the Missouri State Library, serving more than 230 physical branches.

The consortium’s purpose is to share library materials, information, and services using accessible, cost effective methods.  It is our goal to create equal access to materials and information for all of our users.  Today, the MOBIUS Union Catalog has expanded to include more than 29 million items, serving users in Missouri and into Oklahoma, Iowa, Kansas, Arkansas and Texas.  A courier service delivers library materials to member libraries across Missouri and Iowa and connects us to libraries via the CLiC (Colorado) and TransAmigos courier networks.

Ivy Plus Libraries Confederation (IPLC) to Implement ReShare Returnables

The Ivy Plus Libraries Confederation (IPLC) recently announced their intention to implement ReShare Returnables in Summer 2022. IPLC also intends to become a member of the ReShare Community.

IPLC writes “The new software will create more efficient staff workflows, eliminating some of the time and complicated steps needed to deliver items to patrons.”

Project ReShare Welcomes Boston Library Consortium

December 22, 2021

Project ReShare closes out the year by welcoming the Boston Library Consortium (BLC) to the ReShare Community. In addition to contributing leadership and engagement to the Project, BLC will be making a significant financial contribution. Founded in 1970, the BLC is an academic library consortium serving 21 public and private universities, liberal arts colleges, state and special research libraries in the northeastern United States.

The BLC’s collective collection has been a cornerstone throughout its history, and the consortium has always sought creative ways to leverage the collection for the benefit of member institutions. With the transformative opportunity of controlled digital lending (CDL), BLC is once again seeking an opportunity to make resource sharing more valuable and effective for its members. 

BLC’s recent efforts to develop a path forward for consortial controlled digital lending (CDL) have illuminated the significant need for alternative resource sharing technologies to those currently available from vendors, in particular the need for community-led and community-governed alternatives such as Project ReShare. “The current library technology market has left libraries to cobble together solutions that meet local needs that fail to truly capitalize on the transformative potential that CDL offers,” said Charlie Barlow, BLC’s executive director. “The possibilities for an interoperable solution developed collaboratively by and for libraries and consortia hold great promise.”

The initial $100,000 financial commitment from the BLC is intended to accelerate the development path for CDL functionality within the ReShare client. 

For Dorothy Meaney, president of the BLC and director of the Tisch Library at Tufts University, joining Project ReShare offers the BLC the opportunity to magnify its impact by collaborating with other libraries to collectively shape the future of both CDL and resource sharing more broadly. “Our goals for resource sharing align with those of other libraries and consortia,” said Meaney. “Through Project ReShare we see the chance to contribute our expertise and leadership in this space, for the long-term benefit of libraries.” 

The BLC’s CDL Steering Committee, which is guiding the consortium’s implementation of CDL, is prepared to work directly with Project ReShare community members and developers on the development of CDL functionality. As a result of the work that the BLC has done thus far, coupled with its previous discussions with other Project ReShare members and staff from Index Data, the consortium has a great deal of expertise and vision for CDL, and how this can manifest in practical, impactful solutions for libraries and consortia.

Tim McGeary, chair of the Project ReShare Steering Committee, praised BLC’s investment in Project ReShare. “We recognize that such a large financial commitment isn’t possible for everyone, but we hope BLC’s investment will serve as a model for other potential members,” McGeary noted. “Interest in Project ReShare is increasing rapidly, and the financial investments are crucial to our being able to meet the development expectations of the community.”

The decision to join Project ReShare was approved unanimously by the BLC Board of Directors.

November 2021 Community Meeting Recap

On November 15, Project ReShare held a Community Meeting that gave members the opportunity to focus on community-building and sustainability. Attendees had the opportunity to connect with each other in small breakout rooms to discuss the state of the Project and to brainstorm how to help ensure the sustainability of the Project for the future. Members were encouraged to reflect on opportunities and challenges and think about how to increase participation and welcome new members to the community.

In the breakout rooms, members shared that they particularly value the community-focus of Project ReShare and appreciate how ReShare Returnables is able to interoperate with a wide variety of other systems. There was an appreciation for the diversity in library types and sizes involved, and it was noted that there are lots of opportunities for future development as well as enhancements to existing functionality.

The participants also discussed how to ensure the financial and community sustainability of Project ReShare. Attendees provided input on financial and development contributions of members and how to onboard new members with a focus on integrating new and existing voices into the organizational structure of Project ReShare.

ReShare Implementation: An Interview with Jill Morris, Executive Director at PALCI

PALCI went live with ReShare Returnables in August 2021. Clara Fehrenbach, Document Delivery Services Librarian at the University of Chicago and ReShare Communication Team member, interviewed PALCI Executive Director Jill Morris about the implementation.

Project ReShare: When did PALCI go live with ReShare Returnables?
Jill Morris: PALCI went live with ReShare powering its well-known EZBorrow consortial interlibrary loan service on August 12th, 2021. Within just a few short days, we were already seeing requests being generated through our patron search/browse interface (the shared VuFind ReShare discovery layer) and books being delivered to borrowing PALCI institutions. The first patron-initiated ReShare book request to make its way into the hands of a library patron originated at Dickinson College in Carlisle, PA. The item was supplied and delivered by Drexel University in Philadelphia in less than 48 hours. The system correctly identified Drexel University as a supplier for the item, and the staff at Drexel processed the request in ReShare, getting the book to the user even more quickly than most Amazon Prime purchases.

PR: What features of ReShare are most exciting for PALCI?
JM: From the consortium office perspective, we’re thrilled to have the means to support library configurations with a central directory and other staff-facing tools that support easy problem solving and troubleshooting. We can see what’s happening with each request from the moment the patron clicks a button, and while it’s hidden from patron-view, staff can use that information to ensure the system is working properly behind the scenes. We also love the new shared index that was developed as a part of this system to support the sharing of collections. At a glance, we can search and understand what’s held collectively within the PALCI community. 

PR: What are you hearing from member libraries about ReShare?
JM: Library staff are telling us that they like the opportunity to communicate back and forth with each other, right at the point of need. A message feature allows you to connect with the individual working on a specific request without the need for separate email chains and reference back to other systems. We’re also hearing that many faculty users enjoy the discovery interface where they can browse for and filter searches to identify the materials they’re seeking at our 50+ participating EZBorrow libraries.

PR: What has your experience been like leading up to your implementation?
JM: PALCI decided to join the ReShare community prior to it having the name ReShare. For two years prior to ReShare’s official start, a working group within PALCI made up of resource sharing experts, library developers, systems staff, and consortial leadership had put a great deal of effort into identifying and defining a preferred future for next generation resource sharing. In early 2017, it was determined that threats of market consolidation were increasing, and that there was no existing system that would meet the needs of the future defined by that group, so we began seeking out partners to create solutions. The group agreed that it was essential for our choice to include an investment in open and interoperable library infrastructure so as not to repeat the same issues of the past, and so that the end result would remain under the control of the community that developed it. After making our initial contribution to help co-fund the UX design and development work, the decision to implement ReShare was an easy one. We had played a role in designing the system’s requirements, and ReShare represented the potential for innovation and the future our community had defined several years earlier.

The implementation of the system itself was mostly front-loaded with steps to ensure we could properly map the holdings of each library’s collections into our shared index so they could act as suppliers in the system. Setting up the cloud-based tenants for each library was a relatively straightforward process. Our service provider, Index Data, hosts and maintains the implementation. Each library received its own distinct URL and login to set up its staff users. Once set-up, libraries were able to configure their institution’s pickup locations and prioritize various locations and branches as suppliers. The ReShare interface gives our consortium staff tools to help configure the settings for each library, and because most of our libraries already had standard NCIP functionality in place (a set of protocols that allows a central system to talk to disparate ILS systems), we were primarily working through an iterative process of configuration and testing.  We have at least 12 different types of ILS systems in use by PALCI libraries, plus a variety of discovery tools.  ReShare’s use of standards, like NCIP, and open APIs, allowed us to connect to each ILS seamlessly, and in the future, the system will be capable of discovery integrations with local systems too.  

 We were determined to go live with our implementation just prior to the start of the Fall semester to ensure we’d have enough staff back in the office. The launch also coincided with many staff returning to on-site work after more than a year of COVID-related disruptions. We also waited to make sure that ReShare integrations with other tools, like ILLiad, were well on their way to completion. Our biggest hurdle was the sheer volume of institutions we needed to connect, and the many system configuration combinations those libraries represented.The implementation was fast and furious as we approached our target date — PALCI was the very first implementer to go live, and as we went along, we identified some configuration issues that needed resolution prior to implementation. Fortunately, the ReShare development team delivered on solutions each time we encountered a problem, and none of the issues prevented us from using the system. We managed the implementation largely in cohorts, and relied on our community to help support each other in developing system documentation and user guides that will benefit other consortia in future. Today, we have 53 libraries actively using ReShare, and we expect to bring on 15-20 additional libraries in the next 6-12 months. 

PR: What advice do you have for others considering ReShare?
JM: With most proprietary platforms, libraries have to expect that commercial business interests will ultimately win out in all product roadmap decisions, driving further vertical vendor integrations and less choice in the marketplace overall. After all, commercial entities offering proprietary solutions are set-up to operate for profit, whether or not the solutions that drive that profit are actually benefiting users of the service to the fullest extent desired by consumers. ReShare represents an important opportunity to break that cycle and give libraries a real voice in the process. It’s a chance for libraries to co-invest in and shape the future of sharing collections by providing choice and potential for innovation — keeping libraries’ and patrons’ needs front and center through a shared vision and governance model. ReShare is a brand new software – and there are some growing pains that come with that choice. The software is not yet as mature as others out there on the market. Yet the system is breaking new ground with its implementation of ISO18626 — the newest ILL standards, and it’s laying a foundation for greater system interoperability in the future.  It’s an investment that all libraries should be thinking hard about making when faced with the choice. Along those same lines, I think perhaps ReShare’s most important asset is its community. The team of developers from Index Data and Knowledge Integration together in partnership with a group of consortia and individual libraries is unlike most library community projects in that we have a deep wealth of expertise, transparency, shared interests and alignment around vision.
