Selected Articles from Library Technology Guides

The following are a sample of articles related to the major events in the corporate history of SirsiDynix, or you can view all articles related to the company from Library Technology Guides.

Breeding, Marshall, Smart Libraries Newsletter (February 2015). ICV Partners acquires SirsiDynix

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, Smart Libraries Newsletter (December 2013). SirsiDynix Acquires EOS International

SirsiDynix has acquired EOS International from its cofounder and Chief Executive Officer Scot Cheatham effective November 1, 2013. 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, Smart Libraries Newsletter (June 2012). SirsiDynix Development Strategies

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, Smart Libraries Newsletter (March 2012). SirsiDynix Launches a Native Facebook app, Develops eResource Central

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, Smart Libraries Newsletter (July 2010). SirsiDynix Evolution: Recent Developments in the Context of Broad Corporate Strategies

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 longstandingbusiness 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, Smart Libraries Newsletter (February 2010). Developments at SirsiDynix

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, Smart Libraries Newsletter (December 2009). Two major lawsuits jolt library automation industry

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, Smart Libraries Newsletter (August 2008). SirsiDynix launches its Faceted Search Product

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, Smart Libraries Newsletter (November 2007). Composing a Symphony

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, Computers in Libraries (June 2007). The sun sets on Horizon

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.

Breeding, Marshall, Smart Libraries Newsletter (May 2007). SirsiDynix consolidates Its International operations

SirsiDynix took one step in its reorganization following its acquisition by Vista Equity Partners by establishing SirsiDynix International, consolidating all its operations outside North America. Prior to this move, there were separate and often independent sales, support, and administrative operations, including Asia-Pacific, Middle East and Africa, and Latin America. SirsiDynix has a broad international presence, providing library automation software to libraries in at least seventy countries. The international sector is of critical importance to the future of the company. About 25 percent of the company’s customers lie outside the U.S. and Canada. Due to market saturation in North America, the international sector offers the greatest potential market for new sales. SirsiDynix International will be lead by Keith Sturges.

Breeding, Marshall, Smart Libraries Newsletter (April 2007). SirsiDynix ILS set on single course

The June 2005 consolidation of Sirsi Corporation and Dynix created SirsiDynix,which stands as the largest company in the library-automation industry. Although many aspects of the company have been integrated, until recently the company sailed two flagship library-automation systems: Horizon and Unicorn. The company’s mid-March announcement hoists a single flagship—marking a significant change in course—based on the company's Unicorn platform. SirsiDynix entered a new phase of its corporate history when San Francisco-based Vista Equity Partners, a private-equity firm that manages about a $1 billion in assets, acquired it. Announced on December 27, 2006, the transaction closed on January 17, 2007. SirsiDynix reported it would consolidate development efforts into a single ILS platform based on Unicorn. Ongoing development on Horizon has ceased. Horizon 7.4 will be its terminal version. Libraries operating one of the SirsiDynix legacy systems—including Dynix Classic, DRA Classic, INLEX/3000, and MultiLIS—will be offered a migration path to Rome.

Breeding, Marshall, Smart Libraries Newsletter (February 2007). Vista Equity Partners acquires SirsiDynix

The ownership of SirsiDynix has changed, as Vista Equity Partners, a large private equity firm based in San Francisco, will acquire 100% of the company. The parties involved made public their definitive agreement for the sale on December 27, 2006; the deal was expected to close by mid-January 2007. SirsiDynix shifts from a company supported by venture capital into the increasing fold of companies owned by private-equity firms, which assert a more strategic view aimed at increasing value of the company over the longer term.

Breeding, Marshall, Smart Libraries Newsletter (July 2006). Strategic Development: SirsiDynix and Serials Solutions

Breeding, Marshall, Smart Libraries Newsletter (May 2006). SirsiDynix Status

Almost a year has elapsed since Sirsi acquired Dynix to form SirsiDynix in June 2005. During this period, the company has begun to take a more unified shape and is beginning to show its muscle as the powerhouse of the industry. In the last few months, the companyhas announced some major sales, some minor product releases, and appointed a new VP and CFO.

Breeding, Marshall, Smart Libraries Newsletter (November 2005). Settling into SirsiDynix

Following the announcement in June 2005 that Sirsi Corp. would acquire Dynix, the formerly separate companies have been hard at work blending into a single organization. By the end of September 2005, the company publicized who will fill the top- and mid-level management positions. Overall, the executive management structure of the former Sirsi Corporation remains in tact, and most Dynix execs remain onboard as well. The headquarters of SirsiDynix will be located in Huntsville, Alabama. The Dynix office in Provo, Utah, will remain in operation as will the Sirsi office in St. Louis, Missouri. Business, personnel, and administrative functions have been consolidated and will be run out of Huntsville. Pat Sommers leads the company as president/CEO;Jack Blount, former Dynix CEO, continues as senior technical consultant and acting chief technology officer. At year-end 2004, the combined workforce of the two companies totaled 789 full-time equivalent personnel.

Breeding, Marshall, Smart Libraries Newsletter (August 2005). SirsiDynix: the new super-sized ILS company

Days before ALA's late-June Annual Conference and Exposition in headquarter-city Chicago, two major ILS players, Sirsi and Dynix, announced the companies’ pending merger. The agreement the two privately owned companies signed initiates the colossal effort the organizations will undertake in order to emerge as the largest library automation company in the industry: SirsiDynix. The combined company will employ more than 725 and will have potential annual revenues of more than $125 million.

Breeding, Marshall, Smart Libraries Newsletter (March 2005). Sirsi and the NDP

Via the Normative Data Project, or NDP, which Sirsi recently signed on to, Sirsi aims to build an extensive database of library transactions (extracted from libraries nationwide) that can be combined with GIS and demographic data to create a powerful resource that will reveal very specific trends of substantive interest to library decision makers. Ultimately, the NDP hopes to help enable these decision makers to shape their collections and distribute their branches in ways that will improve their services, i.e., better targeting of under-served patrons.

Breeding, Marshall, Information Today (February 2002). SIRSI announces the demise of Taos: another system falls away in the library automation market

Breeding, Marshall, Information Today (July/August 2001). SIRSI Acquires DRA

Consistent with the trend toward consolidation in the library automation industry, SIRSI Corp. has purchased one of its major competitors, Data Research Associates, Inc. While SIRSI has been steadily attracting new customers and developing new products, DRA has been facing declining revenues, a steady decrease in libraries operating its older products, and sluggish acceptance of its next-generation Taos library automation system. This acquisition further strengthens SIRSI’s position in the marketplace.

Breeding, Marshall, Information Today (March 2000). Epixtech partners with Citrix Systems on ASP solution for library automation

epixtech announced the availability of a new approach in library automation where the company serves as an Applications Service Provider, or ASP, delivering access to its Horizon automation software via the Internet. This new product combines the Horizon library automation software from epixtech and the Application Server Provider program offered by Citrix Systems.

Breeding, Marshall, Information Today (January 2000). epixtech: a new beginning for ALS

Ameritech Library Services (ALS) has been sold. It has undergone a major transition from being a subsidiary of Ameritech—a large telecommunications corporation—to that of a privately owned company. On November 5, Ameritech announced the sale of its ALS division to a pair of investment companies, the 21st Century Group, LLC, and Green Leaf Ridge Co., LLC.

Library Systems Newsletter (November 1999). Ameritech Library Systems changes owners

Ameritech Library Services (ALS) will be acquired by a private investment group led by 21st Century Group and Green Leaf Ridge Company. Headquarters will stay in Provo, Utah and the staff of 520 will grow, rather than shrink, because the reconstituted company's goal is to commit a more substantial portion of revenues to product development and sales. [John Ware, president of 21st Century Group died in May 2010]

Deseret News (Nov 6-7, 1996). Library services firm appoints president
