Breeding, Marshall. The History of SirsiDynix. January 2025. Library Technology Newsletter. SirsiDynix has become established as the largest standalone library technology company, continually expanding over its 40-year business history. The company has developed important library technology products which have been implemented by libraries across many global regions. It has also expanded through the acquisition of competitors, many of which had seen their own cycles of mergers and acquisitions. SirsiDynix traces its business history through Sirsi Corporation, Dynix, Data Research Associates, and several other companies each with their own interesting narratives. At least fourteen antecedent companies are represented in its corporate lineage.

Breeding, Marshall. SirsiDynix acquired by Harris Computing. January 2025. Library Technology Newsletter. SirsiDynix, has been acquired by Harris Computing, one of six operating companies of Constellation Software, Inc. It purchased SirsiDynix from ICV Partners, a private equity firm that has owned it since February 2015. Unlike private equity firms, Constellation does not sell the companies it acquires.

The acquisition marks a definitive exit from ongoing cycles of private equity investment into a permanent position within a public company specializing in the administration of technology-focused businesses. SirsiDynix has seen two rounds of private equity ownership, including Vista Equity Partners and ICV Partners.As part of Harris, SirsiDynix gains access to additional technical and financial resources. Harris has deep experience in acquiring and strengthening technology companies. In contrast, SirsiDynix was the only technology company within the ICV Partners portfolio.

Breeding, Marshall. ICV Partners acquires SirsiDynix. February 2015. Smart Libraries Newsletter. A new era in the corporate history of SirsiDynix, one of the corporate giants of the library technology industry, has begun. After over eight years of ownership, Vista Equity Partners has sold SirsiDynix to ICV Partners, with Vista retaining and company executives acquiring minority stakes in the company. While it is too early to assess how new investment owners will shape the direction of the company going forward, it is clear that SirsiDynix remains a major force in the industry with a very large number of libraries relying on its success. SirsiDynix, along with other Ex Libris, Innovative Interfaces, and Follett Corporation, ranks as a giant in the industry, which also includes dozens, if not hundreds, of mid-sized and small companies. Each of these four companies has earnings in the range of $100 million, develops strategic technology products for libraries, though each follows quite different business strategies and has distinct profiles of customers according to type and geographic region. Globally diverse, SirsiDynix supports customers in over 70 countries. SirsiDynix has a long and interesting history that spans many different companies, products, and personalities. This issue of SLN, examines SirsiDynix, working through the phases of its corporate history, its product strategies, and the potential impact of this business transition.

Breeding, Marshall. SirsiDynix Acquires EOS International. December 2013. Smart Libraries Newsletter.

The transaction was conducted entirely from financial resources within SirsiDynix without additional backing from its private equity owner, Vista Equity Partners. The acquisition of EOS International will expand the presence of SirsiDynix in the small library arena, and will strengthen its overall position in terms of revenue, customers served, and product offer ings. SirsiDynix provides a stable and expansive business environment for the ongoing support, development and marketing of EOS International products.

Breeding, Marshall. SirsiDynix Development Strategies. June 2012. Smart Libraries Newsletter. In recent years, SirsiDynix has been executing a development agenda that provides libraries with tools and interfaces to improve access to their collections and services. The company continues to make improvements in the functionality of its strategic integrated library systems, Symphony and Horizon, concentrating especially on the development of patron-facing tools. These interface products address the different methods with which patrons might want to access the library: BookMyne and BookMyne+ for iOS and Android based mobile devices, Enterprise and Portfolio for the Web, and the Social Library for Facebook. SirsiDynix has also launched eResource Central for access and management of e-books, complementing the capabilities of its Symphony and Horizon ILS products in managing a library's print collection.

Breeding, Marshall. SirsiDynix Launches a Native Facebook app, Develops eResource Central. March 2012. Smart Libraries Newsletter. SirsiDynix launched two new products at the ALA Midwinter conference: the SirsiDynix Social Library and eResource Central. These products continue the company's efforts to create forward-looking products and technologies surrounding its ILS products.

Breeding, Marshall. SirsiDynix Evolution: Recent Developments in the Context of Broad Corporate Strategies. July 2010. Smart Libraries Newsletter. SirsiDynix has taken a number of actions that consolidate and focus its corporate resources. On May 12, 2010, SirsiDynix launched a new Web site and announced a number of major changes related to its operating facilities and its organizational approach to customer service. These moves represent incremental steps toward a number of longstanding business goals. The company positions its moves as offering significant benefits to the libraries that use its products through improved communications channels and more sensitivity to the individual needs of each customer. As a company that serves something over 20,000 library facilities spanning over 70 countries worldwide, these adjustments will have a broad impact.

Breeding, Marshall. Developments at SirsiDynix. February 2010. Smart Libraries Newsletter. SirsiDynix, one of the largest library automation companies, made a number of recent announcements relating to both its products and personnel. December 2009 saw the release of new versions of its major products and the departure of a key executive.

Breeding, Marshall. Two major lawsuits jolt library automation industry. December 2009. Smart Libraries Newsletter. In recent months, two major lawsuits have been filed in the the library automationindustry. Queens Borough Public Library filed a complaint on July 2, 2009 against SirsiDynix for breach of contract and 3M has filed suit against EnvisionWare for patent infringement. Both of these lawsuits address interesting issues that bring pivotal libraryautomation legal concerns to the surface. Neither accusation has been proven, and both are still pending legal action or settlement. The complaints filed with the courts stand as public documents exposing the plaintiffs’ concerns in detail. The defendant’s response to those claims may not become public until the issue comes before a court, or may never be disclosed if the parties settle out of court. While major lawsuits attract much attention, they must be considered skeptically until both sides of the matter can be understood.

Breeding, Marshall. SirsiDynix launches its Faceted Search Product. August 2008. Smart Libraries Newsletter. SirsiDynix has entered the fray of next-generation library interfaces with the announcement of SirsiDynix Enterprise, a search product that features faceted navigation, built using the GlobalBrain data retrieval technology from BrainWare, Inc.. Both SirsiDynix and BrainWare are portfolio companies of Vista Equity Partners.

Breeding, Marshall. Composing a Symphony. November 2007. Smart Libraries Newsletter. SirsiDynix has rebranded Unicorn, their strategic ILS product as Symphony. The company indicates that the initial release of the product will be called Symphony 3.2, reflecting its heritage as an incremental extension of Unicorn 3.1, the last version offered under that name.

Breeding, Marshall. The sun sets on Horizon. June 2007. Computers in Libraries. SirsiDynix announced that it had discontinued development of Horizon and would consolidate its future ILS efforts on Unicorn. Events such as SirsiDynix’s decision to consolidate to a single product cause a great deal of uncertainty and disruption for libraries and detract from the trust that’s necessary for a successful relationship between a library and its automation products supplier. SirsiDynix faces a large challenge in shoring up the trust with the Dynix/Horizon half of its customer base. The prompt delivery of truly outstanding replacement products is the only salve that will heal the wound.

2024 SirsiDynix Accomplishments Narrative

2024 Year in Review – SirsiDynix

2024 saw a number of key developments that moved SirsiDynix forward in significant ways. Below are three major events we saw in 2024.

First, SirsiDynix released our bespoke, next-generation mobile app, BLUEcloud Mobile2, in July. This app was developed on state-of-the-art technology for both iOS and Android platforms. Functionally comparable with the original BLUEcloud Mobile, it also boasts a number of new features that were not previously available. With a release schedule of between 30-60 days, BLUEcloud Mobile2 is constantly being improved with new functionality being added on a regular basis.

Next, 2024 saw the announcement of the BC Accelerate initiative. BC Accelerate is a product investment that increases the number of engineers working on five core BLUEcloud products: BC Discovery, BC Mobile2, and BLUEcloud CIRC, CAT and ACQ. In many cases, the size of the development teams working on these key products more than doubled.

The purpose of BC Accelerate is to bring these core products to the point where the vast majority of customers, including Academic, Public, School and Special, will be able to use them exclusively, without needing to supplement library functions using our legacy Symphony and Horizon clients. Announced on July 31, 2024, the results to date for BC Accelerate have been promising. Not only have the number of features being actively developed increased, but the timeline for their completion has been significantly accelerated.

Finally, and most significantly, on December 24, 2024, SirsiDynix was acquired by Harris Computer, a vertical market software group that is part of a larger business called Constellation Software. After ten years of ownership by Inner City Ventures (ICV), and two decades of private-equity ownership in general, SirsiDynix has found its permanent home with Harris. This is encouraging news for customers and prospective customers of SirsiDynix.

Here are the key points that customers wanted to know about the acquisition.

Moving forward, SirsiDynix will continue to operate as a stand-alone business within the Harris group of specialized software companies.

This acquisition marks the end of the private equity ownership era for SirsiDynix. Harris and its Constellation affiliates are permanent acquirers. The businesses acquired by Harris do not get sold—in part or in whole—once they are part of the Harris family. This means all business strategies and decisions are focused on long-term success rather than short-term objectives.

Further, Harris is fully committed to the previously-mentioned BC Accelerate product investment and intends to continue with that exciting initiative. SirsiDynix, under Harris, will continue to innovate and deliver on the product roadmap developed over time with extensive customer input. And importantly, the same people who assisted customers with their projects and issues previously will be the same people who will assist them going forward.

This acquisition will not affect any partnerships, product integrations or other company initiatives currently in place. If anything, SirsiDynix anticipates being even a stronger partner to the library community and enhancing their leadership position as they benefit from the financial and technological prowess of their new owners. Harris is patient, deliberate and invests consistently and incrementally over the long term to achieve the best possible outcomes for their customers. This means that SirsiDynix will be managed to endure and thrive for decades to come. The entire SirsiDynix team looks forward to building a wonderful future together that includes their new friends at Harris, their exceptional employees and especially, their valued customers.

Finally, it is noteworthy that our 7th annual Connections conference, held on October 24-26, 2024, saw the highest registration ever, with over 2400 librarians from all over the world registering and participating in Connections. We appreciate our wonderful customers and libraries everywhere. At SirsiDynix, we believe in the power of libraries.
