Libraries and Publishers Working Together: an Interview with Project Euclid’s Leslie Eager

Project Euclid is a not-for-profit hosting and publishing platform for the mathematics and statistics communities, administered jointly by Cornell University Library and Duke University Press. We recently chatted with Leslie Eager, Director of Publishing Services for Project Euclid at Duke University Press about the project and her position. 

Tell us a bit about yourself and your position.

LeslieEagerI became the director of publishing services for Project Euclid just over a year ago and before that worked in marketing and sales for about five years, focusing on the academic library market. Project Euclid provides online hosting services for mathematics and statistics scholarship. I was attracted to the job because I believe in the mission, and I love that it’s a small shop where one person gets to operate in many sectors of the scholarly publishing business. I studied literature and did actually minor in math and physics without expecting it to ever come up again. But here we are! Not that my college background remotely equips me to understand new mathematical research–sadly, it doesn’t, and I don’t!–but I deeply admire the field and am glad to support it.

Euclid is a quite interesting project that is jointly managed by Cornell University Library and Duke University Press. It was started at Cornell in the early 2000s when journals just started going online. Folks at the library recognized the growing demand for online publishing suddenly required small publishers to confront a whole new set of technical skills and requirements. For math journals specifically, the need to get online prompted many formerly independent and inexpensive journals to sign up with the big commercial presses like Elsevier and Springer. The journals went online, but subscription prices rose dramatically. The Library, which has long been very innovative, had a great idea that they would provide an alternative way for small, non-profit, or society publishers to get their literature online while remaining independent. The solution was Project Euclid, an online content platform for mathematics and statistics scholarship that is easy-to-use and affordable but powerful enough to be competitive.

Duke University Press joined Cornell in running Euclid in 2008, and now the folks at the Library handle the technical side of the site, and the team at the Press handles the business: publisher relations, acquisitions, marketing and sales, customer relations, finances. It means my team, that works exclusively on Euclid, also collaborates with people in the marketing and sales department, the IT department, and other staff at the Press to make the program work. We partner with about 30 publishers located all over the world, and we host about 60 active titles. Some of the titles are subscription based, some of them are open access titles, and some of them are part of collections we sell to libraries. Every publisher controls their own business model and we try to provide the most functional and affordable hosting services possible.

What is the new direction for Project Euclid?


Over the last few years, our new partnerships have been more and more focused on open access models. I think mathematics is an especially idealistic and activist community, and mathematicians are speaking out forcefully against those publishing practices that tend to be very expensive and throw the entire ecosystem of library subscriptions out of whack. As a result, more and more journals are trying to cast off all those old subscription costs and operate as open access publications. Euclid tries to support this effort by providing low cost but still truly excellent hosting services to those journals. We also think it’s beneficial to be a part of the Euclid publishing community, even if you’re independent. Associating your publication with similar titles makes your open access journal more discoverable, and our specialization in mathematics and statistics allows us to make your content as compatible with other math research tools or library systems as possible. We are also trying to garner our resources to make as much material on the platform openly available as possible. Most subscription-based content on the site is governed by some kind of moving access wall determined by the publishers that makes the literature freely available after three, four, or five years. The Euclid Prime collection we sell to libraries is composed of 28 titles and after five years all of that journal content becomes open access. All told, over 70% of the articles on the site are freely available to anyone with internet access.

What are your top priorities for Project Euclid?

One of my top priorities is to communicate as effectively as possible what value Project Euclid can bring to the publishing ecosystem. Publishers have a lot of options these days. If they want it to be open access, there could be a strong temptation to sign up for a WordPress site and start throwing articles up there. This is quick and really inexpensive, but at the end of the day, they’re losing out on the kind of functionality that will actually make their journal influential and competitive with all the other big publishers that have tons of resources. So I want to communicate the practical value Euclid is providing in disseminating scholarship. I want us to be affordable but still realistic about what it means to operate a sustainable project in the current market.

Another one of my top priorities was acquiring new content for the platform, and it’s been incredibly encouraging and rewarding because we were able to add 11 new journals to the platform in 2017. That’s a combination of open access, subscription-based, and collection-based content. It feels really energizing that what I thought was going to be the most challenging piece of my job—forming new partnerships—is actually the thing that has been by far the biggest success in the very first year. It suggests there are still a lot of journals out there that could benefit from Euclid’s services.

How is the project financially structured?

PE HOST OR SALESPublishers join Project Euclid under a couple of different publishing hosting models. If they want to control all of their own marketing and sales, and they only want Euclid for hosting services, they just pay us a straight set of hosting fees based on the amount of content they publish and whether they’re open access or subscription based.

On the other hand if you’re a publisher that wants hosting services but also wants support in marketing and sales, then they can join our Euclid Prime collection. This is the collection we sell to libraries on behalf of publishers. At the end of the year, the revenue we generate from those sales is divided, and part of the money supports Euclid’s operations, and part of the money is paid out to publishers as royalties. We’re really happy the revenue from Euclid Prime sales is part of what makes it possible for us to offer these really affordable hosting fee prices to open access titles. Overall we like to think there’s balance: we hope the collections we’re selling to libraries provide good value for the library but also contribute to our mission to make as much as much of the content freely available as possible.

What are the goals you have for Project Euclid?

One of our projects for the next year is to do an exploratory audit of what is available out in the world when it comes to hosting platforms. Right now our platform is entirely homegrown and based at Cornell, but we always want to make sure we’re offering the most relevant and affordable functionality we can so we’re planning a request for information process to see what other kinds of technical solutions there are in the market and whether they would serve our customers any better.

PEPI continue to be really focused on building new partnerships, especially trying to bring new partners into the Euclid Prime collection. We think this is a really, really good way for publishers to generate sustainable revenue streams while still being really good citizens of the mathematics community and not over burdening libraries with excessive costs. I’m always in talks with new partner publishers and trying to help them make a decision to join our collection.

Our biggest new product for 2018 is our new joint partnership with MSP and Duke University Press to offer MSP on Euclid, a collection of seven journals available to libraries. MSP is a fine organization with a similar size and mission, and we hope that cooperating in a competitive marketplace will generate new opportunities for all three partners.  

What is the most rewarding aspect of your job?

The most rewarding part of being on the Project Euclid team is that we are a truly mission-driven operation, and our only goal is to provide services that can help make content as available and excellent and discoverable as possible. There’s a really committed group of librarians and scholars and publishing professionals who are invested in that mission, and they come up with lots of creative ideas to push it forward. I’ve enjoyed learning from them and developing new strategies for being the best possible citizen of the scholarly publishing community.

Duke University Press Signs French National License Agreement with ISTEX

istex.pngDuke University Press has signed a major agreement with ISTEX, a French national licensing program, to make the Duke Mathematical Journal (DMJ) available to French research institutions.

With this agreement, 112 volumes of content from DMJ are made available to millions of users at over 330 French universities, grande écoles, research institutes, and libraries. Published by Duke University Press since its inception in 1935, DMJ is one of the world’s leading mathematical journals. DMJ emphasizes the most active and influential areas of current mathematics and has several distinguished French mathematicians on its editorial board. The journal has published work by the Fields Medalists Cédric Villani, Ngô Bảo Châu, Jean-Pierre Serre, and Artur Avila.

Since 2012, ISTEX has facilitated the massive acquisition of archives of scientific and mathematical production in all disciplines made available to public institutions of higher education and research in France on one central platform.

David Aymonin, Head of the Bibliographic Agency for Higher Education, says, “All the four partners leading ISTEX are happy to add quality mathematics content from the Duke Mathematical Journal to the ISTEX initiative through our arrangement with Duke University Press. We see this partnership as bringing important mathematics scholarship to more researchers throughout France.”

“The Press is delighted to have the opportunity to participate in the ISTEX project by offering content from the Duke Mathematical Journal, including eminent French scholars, for use by mathematicians throughout France.

Announcing MSP on Euclid, a Partnership between MSP, Project Euclid, and Duke University Press

MSP-on-EuclidMSP (Mathematical Sciences Publishers), Project Euclid, and Duke University Press have partnered to launch the MSP on Euclid collection, bringing seven mathematics journals published by MSP together with the strong functionality available through the Project Euclid platform.

Dedicated to providing alternatives in math publishing, MSP, Project Euclid, and Duke University Press are all not-for-profit and have similarly sized programs. The goal of the MSP on Euclid collection is to offer libraries new features as well as the option to consolidate their platforms. MSP on Euclid includes the same seven journals sold by MSP in their MSP package but now also hosted by Project Euclid and sold by Duke University Press.

“Project Euclid is pleased to welcome seven of MSP’s distinguished journals to our platform and to work with Duke University Press on increasing their dissemination,” said Leslie Eager, Project Euclid’s director of publishing services. “Our three organizations strive to provide the mathematics community with truly excellent not-for-profit publishing services, and we look forward to strengthening our impact through this collaboration.”

“MSP is committed to finding new ways to make mathematics publishing more sustainable and to bring our content to scholars around the world. We hope this new collaboration will benefit researchers as well as libraries,” said Rob Kirby, chief executive of MSP.

MSP on Euclid provides institutional subscribers with valuable enhancements of the MSP package still available from MSP. Project Euclid’s platform offers libraries a subscription management tool that stores librarian contact and IP information. Institutional subscribers gain COUNTER- and SUSHI-compliant usage statistics exclusively through the platform. Single sign-on authentication through Shibboleth is also available. Duke University Press provides institutions with all sales services and customer support for the collection.

“Duke University Press has been publishing mathematics scholarship for over 80 years. We hope that our experience in math sales and customer support will bring MSP’s well-regarded, high-quality content to a wider audience,” said Steve Cohn, director of Duke University Press.

To learn more about these open-access initiatives at Duke University Press, read our previous blog posts.

Open Access: Project Euclid

We have created a series of five blog posts covering open access at Duke University Press. Today’s post features Project Euclid, a not-for-profit hosting and publishing platform for the mathematics and statistics communities, managed jointly by Cornell University Library and Duke University Press. Here Leslie Eager, Director of Publishing Services for Project Euclid, shares more about the platform and the ways it supports open access in the mathematics and statistics world.

peOur goal at Project Euclid is to make mathematics and statistics publications easy and affordable to find and read online. Supporting open-access publishing is a huge part of that mission. About 70% of Project Euclid is open access.

With Project Euclid the idea is to provide low-cost but feature-rich hosting services for journals, books, and conference proceedings so that publishers can keep the scholarship affordable and widely available to libraries and researchers while sustaining themselves financially. We partner with math and stats publishers around the world.

Some editors of open-access journals ask us why they should work with a formal publishing platform at all. It’s true that anyone can post articles on a web page at little or no cost, but it’s much harder for readers to discover those articles. Journals hosted on Euclid are fully indexed, compatible with library discovery systems, tagged with Mathematics Subject Classifications, search-engine-optimized, and linked directly to crucial mathematics resources like MathSciNet reviews, zbMATH, and arXiv.

We work with subscription-based publications as well as open access, but we offer special low pricing to publications with no access restrictions. We also encourage publishers to make their subscription-based content freely available after three to five years. The result is that across the 87 titles that we host, over 70% of the pages on Project Euclid are freely available to everyone.

Exciting opportunities

acta-mathematicaIt’s very exciting when long-standing, highly regarded journals find ways to open their content and become more easily available. Beginning in 2017, Acta Mathematica and Arkiv för Matematik will become open access and will be hosted on Project Euclid with issues going back to 1882. Both are high-quality journals (published by the Institut Mittag-Leffler and produced and distributed by International Press), and Acta is consistently ranked among the very top journals in the field, according to Impact Factor. We believe that making journals of their stature open access will bring new visibility to the open-access business model and to Euclid as a leading partner in open-access publishing.

We also offer partial open-access solutions to publishers that are unable to secure full funding for their publications. The Euclid Prime collection hybrid model allows 25% of its material to be open access in the first five years, and all the journal content becomes openly available to all after that time. Prime publishers pay no out-of-pocket hosting fees and earn royalties from Euclid’s sale of the collection to libraries. Through Euclid Prime, Project Euclid is able to help fund partially open publishing initiatives by charging a low fee for the most recent content. Visit the Project Euclid site for a full list of all open-access titles.

Congratulations to Jean Bourgain, Winner of the 2017 Breakthrough Prize for Mathematics


Jean Bourgain

Congratulations to Jean Bourgain, an editor of Duke Mathematical Journal, winner of the 2017 Breakthrough Prize for Mathematics. The prize honors the world’s best mathematicians who have contributed to major advances in the field. The Breakthrough Foundation, founded in 2012, rewards physicists, life scientists, and mathematicians for their work on cutting edge research.

Bourgain, a mathematician at the Institute for Advanced Study, Princeton University, was awarded the prize for multiple transformative contributions to analysis, combinatorics, partial differential equations, high-dimensional geometry, and number theory. From the New York Times:

Some recent work includes a “decoupling theorem” — a sort of very abstract generalization of the Pythagorean theorem applied to oscillating waves like light or radio waves. While Pythagoras merely showed how the length of the two shorter sides of a right triangle are related to the longer hypotenuse, the decoupling theorem proven by Dr. Bourgain and Ciprian Demeter of Indiana University shows similar relationships in the superposition of waves.

Dr. Bourgain’s work published in Duke Mathematical Journal and several other journals is available on Project Euclid.

In addition to the Breakthrough Prizes, several authors have won New Horizons Prizes, $100,000 awards in physics and mathematics. The New Horizons mathematics winners include Mohammed Abouzaid of Columbia University, Hugo Duminil-Copin of the University of Geneva, and Geordie Williamson of Kyoto University. Please visit Project Euclid to find articles by these award-winners.

Journals from the Tusi Mathematical Research Group join Duke University Press

Logo-TMRGDuke University Press is pleased to partner with the Tusi Mathematical Research Group, based in Mashhad, Iran, to publish the Annals of Functional Analysis (AFA) and the Banach Journal of Mathematical Analysis (BJMA). In 2015, Duke University Press will begin publishing both journals.

Founded and edited by Professor Mohammad Sal Moslehian, AFA, started in 2010, and BJMA, started in 2007, are online-only journals included in the prestigious “Reference List Journals” covered by MathSciNet and indexed by ISI and zbMATH. With the start of their 2015 volumes under the guidance of strong editorial boards, the journals will increase in frequency from two to four issues per volume per year. The journals publish research papers and critical survey articles that focus on, but are not limited to, functional analysis, operator theory, and abstract harmonic analysis. AFA and BJMA have rapidly established themselves as providing high-level scholarship that addresses important questions in the study of mathematical analysis.

Both the Annals of Functional Analysis and the Banach Journal of Mathematical Analysis will continue to be available on Project Euclid and in Euclid Prime.
