New link partnership – welcome ZB Med!


In a new link partnership announced Friday, September 19th 2015, the Leibniz Information Centre for Life Sciences (the German National Library of Medicine – ZB MED) will link to 12 million articles on DeepDyve, which offers unlimited research article streaming from the cloud for just $40 per month.

To find out more about DeepDyve, please see our 2014 Progress Update for stats and facts about our service, who uses us, why they do and our growth.

“We are very pleased and excited to work with ZB MED, a global resource for the life sciences,” said William Park, CEO of DeepDyve. “For online users, it has become quite normal to rent or stream content from the cloud – whether music or films. With DeepDyve and LIVIVO, scientists in Germany can now gain convenient and affordable access to needed literature.”

The German National Library of Medicine (ZB MED) is the world’s largest library in its subject combination of medicine, health and nutritional, environmental and agricultural sciences.

Their semantic-based interdisciplinary search portal called LIVIVO, retrieves information across more than 45 life sciences data sources including library catalogues, databases and publisher directories. With more than 55 million records, LIVIVO allows the user to search beyond the limits of their holdings and now, users can choose to subscribe to DeepDyve and get instant access to articles on our platform too.

DD logoOn the topic of content supply in the digital age, Dr Elisabeth Müller, head of collection development at ZB MED said:

Through our cooperation with DeepDyve we are taking a decisive step forward.

DeepDyve is also now integrated with PubMed as a LinkOut resource, a service that allows users to link directly from PubMed to relevant online resources in order to extend, clarify, and supplement information found there. And, we have a new IE plug-in which runs with Google Scholar, Google and PubMed to show users which articles are available to rent from us.

With the additional option for LIVIVO users to test the service FREE for two weeks and cancel at any time, we welcome them to our world of instant and affordable research!

How to quickly see if a journal is available on DeepDyve

One of the most frequent questions that we get asked here at DeepDyve is:

Do you carry this specific journal?

In this time limited world, our audience wants a rapid answer so we’ve developed a comprehensive journals list for this purpose.

Are jrnls availableThe list is alphabetically sorted and the journal’s availability in our library is clearly marked. Titles which you can read today are marked “Available“. Those where the full text is on our platform because they are free to read are marked “Free“. Articles that we want to make available to read but have not yet been able to obtain publisher permission are marked “Preview only” – their usage (or lack thereof) triggers us to lobby a publisher again for their inclusion. Finally, our latest journals are marked “New!

It’s also worth knowing that we have implemented an article recommendation system. Here’s how it works:

1) If we have references and have those articles in our system, we show those at the top of the list
2) We show articles that have similar titles/abstracts

And, we’re currently working on an additional feature that will show what content “other users like you also read”. We will soon be able to suggest articles that are related by author and use the connection between references and citations to find more content.

Here at DeepDyve, we’re committed to make the quest for access to research as smooth and seamless as we possibly can.

Spring Subscriber Survey – results to share

If you, (like us) love stats, then you will enjoy this update on some key results from our Spring Subscriber Survey which received 530 responses, a 7% response. A big thank you to everyone who completed it. The results will help us enhance our services for the benefit of all (some new features are already in development so watch this space).

Here are a few highlights.

  • Nearly 90% of subscribers rate our service as excellent or good
  • 85% of respondents work at a business with fewer than 500 employees
  • 71% of respondents use DeepDyve at least 3 times per month

The top three reasons to subscribe to our service are:

  1. Not affiliated with an academic library
  2. Convenience of having articles at my fingertips
  3. Can’t afford to purchase single PDF’s

In terms of what we offer, we provide unattached researchers with ongoing instant and affordable access to 12 million scholarly articles from 10,000 top peer-reviewed journals for just $40 per month:

• Read as many as they like
• Print up to 20 pages per month
• Download PDFs for 20% off

Here are a few memorable quotes from the survey about why our subscribers use our service:

Buying PDF’s one at a time for $30-40 would be prohibitive given how many I need – anon 1.

I love that I can see the articles without having to purchase each PDF. For me, learning new things includes having to have a breadth of information about a topic, so purchasing single PDFs all over the place is annoying, time consuming, and elitist for people who can’t afford the high prices for single pieces – anon 2.

For accessibility to relevant articles and journals associated to my research work – anon 3.

Article sharing in the digital age

This February, the International Association of Scientific, Technical and Medical Publishers (STM) opened a community-wide consultation about the article sharing that takes place on Scholarly Collaboration Networks (SCN) such as: ResearchGate, and Mendeley.

If you are new to the SCN concept then this quote from a blog interview with Fred Dylla (CEO and Executive Director of the American Institute of Physics who leads the SCN working group), will help you to understand their growing role:

The ways by which scholarly information is delivered and used by researchers is rapidly evolving. Researchers have always shared copies of articles from the inception of the journal when print copies were shared among collaborators. Sharing an electronic copy with a colleague is now done with a key stroke. Sharing networks facilitate the dissemination of articles and related information among an entire collaborating group. Internet tools have simply improved the efficiency of a standard academic practice. As the use of sharing networks increases, ambiguity has grown over how to access, share and use journal articles on platforms and tools like SCNs.

Our subscribers know all about the difficulty of article sharing from first hand experience and unlike many of those seeking information via SCN, they are not affiliated to an academic library. The solution that we offer them is instant and affordable access ($40 per month) to over 12 million articles from 10,000 peer-reviewed journals and naturally we’d be delighted if article rental technologies like ours and others could also help to facilitate legitimate and unambiguous article sharing.

Representatives of the following organizations drafted these voluntary principles on article sharing and asked for feedback from the community via a series of questions.

  • AAAS
  • American Chemical Society
  • American Institute of Physics
  • AIP Publishing
  • Digital Science
  • Elsevier
  • IEEE
  • John Wiley & Sons
  • Nature Publishing Group
  • Springer
  • Taylor and Francis

We are sharing our answers with you below, as part of our commitment to transparency (you can also find our 2014 Annual Report here). You can see all the submissions here. We want to know what you think of our reply, a key part of which is that:

There are many stakeholders that are interested in a sensible solution to article sharing and collaboration. First and foremost researchers themselves; publishers; funders, and article service providers (such as ourselves and others)…I believe expanding the working group to include additional stakeholders would be useful to introduce a broader set of ideas and perspectives.

DeepDyve’s contribution to the STM consultation on Article Sharing

Here at DeepDyve we develop innovative technologies to empower the discovery and access of authoritative research for those who are not affiliated with a library. As CEO, I welcome the consultative approach of the publishers who were involved in drawing up these voluntary principles. I agree with Fred Dylla that “consensus building is a process and we all benefit from increased dialogue”.

By way of some background on our organization, we were the first to enter the article rental market in 2011, are independently owned, and represent more publishers than any other comparable vendor with over 12 million rentable articles from more than 10,000 peer-reviewed journals.

Since our launch, we’ve been improving our product to meet the needs of our subscribers, doubling in size each of the past 3 years. Similar to other online subscription services, users can register for a two week risk-free trial. Should they continue beyond the trial, they can rent and read-only as many articles as they wish for $40 per month.

In many respects, the fact that we facilitate legitimate access to pay-walled research articles puts us in a unique position to comment on these draft principles. With this in mind, I have responded to each of the five core questions.

Q: What impact do you think a unified approach to scholarly article sharing would have?

I think the key word here is “unified”. There are many stakeholders that are interested in a sensible solution to article sharing and collaboration. First and foremost researchers themselves; publishers; funders, and article service providers (such as ourselves and others). To date, SCN’s have (with the exception of Mendeley) been notably absent from industry wide discussions but they are hugely popular with researchers. If a unified approach could be created and implemented, the impact would be tremendous in fostering collaboration and dissemination.

Q: Do you have other ideas about how the sharing of scholarly research should function within the research community?

First, I think it is impractical to try to define a ‘typical’ size of a working group. Aside from the challenge of agreeing on a number, there is the question of who (or how) will this size be monitored and enforced? And as technology advances (e.g. Wikipedia), is it anachronistic to even attempt to define or limit the size of a working group?

Second, how will you define the ‘purpose of the group? Will researchers have to utilize a standard tool or process for creating a group, inviting ‘suitable’ members, etc.? And who will build this tool, and who will audit these groups to ensure that they are in compliance, and that only appropriate articles are shared?

Third and related to my first point, is it reasonable to exclude the ‘general public’? As other commentators have pointed out, what about corporate scientists and citizen scientists (some of whom will complain about lack of access to research they funded out of their tax dollars) and of course patient groups? DeepDyve serves many of these customer segments and we believe it would be a costly mistake to ignore them, and per my earlier point, challenging and impractical to implement.

While publishers offer individual policies for author sharing and public access, this current patchwork is inconsistent with the Voluntary Principle “to make sharing simple and seamless”. In fact, it is quite possible that this fragmented landscape ironically helped propagate the very success of the SCN’s. With claiming over 19 million members and ResearchGate likely in the same vicinity, unfortunately the cat may be out of the bag and publishers must offer a unified, simple way to allow access in a manner that is reasonable and convenient. Having stated that, I also believe that it is unreasonable to give away premium content that required considerable investment to produce without anything in return.

A balance needs to be achieved, and I believe trying to define sharing is going in the wrong direction, and the attention should be on the access itself – we should focus on defining levels of access, rather than levels of sharing. In that respect, I suggest that sharing be unlimited. Allow anyone to share anything with anyone. Not only does it align with all the stakeholders’ aspirational goals concerning dissemination, it again would also be challenging to implement a system that somehow manages the activity of such a diverse audience across such a diverse set of platforms where people could possibly share.

If there are limits to be applied, apply them towards access where “FREE” remains a reasonable option, along with additional premium options. In our new world where there is growing pressure ‘for all information to be free’, there will be a growing need for innovative new models of access. Rental companies such as DeepDyve employ this strategy in allowing users to sample an article for free, rent and read-only the full-text for a modest amount, and PPV for full PDF ownership.

Q: It is our aim to continue to refine the thinking and approach to article sharing. What feedback or guidance can you offer for further consideration or to help next steps?

For any unified proposal to be successful, it must offer the user an experience comparable to what they experience today on SCN’s to ensure adoption and compliance. On a positive note, it will have the significant advantage of allowing authors and readers the ability to share and access articles legally (that was a huge advantage of iTunes when it launched: it made it easy and affordable for users to do the right thing); second, it must be reasonably priced; third, it must be cross-publisher to replicate the convenience of accessing everything from one place; and fourth, it must be simple and easy to use with a consumer-oriented design.

Q: Would your organization be willing to actively participate and contribute to this process?

Yes we would.

Q: Do you support the STM’s initial outline ‘Voluntary principles for article sharing on scholarly collaboration networks’?

I think it is an important first step. In addition, I believe expanding the working group to include additional stakeholders would be useful to introduce a broader set of ideas and perspectives.




2014 in review (and what a great year it was!)

Here at DeepDyve, we develop innovative technologies to empower the discovery and access of authoritative research, for those who are not affiliated with a library.

There are about 230 million or more knowledge based workers in the world and while about 20 million or so work in academia and likely have access to research content, many of the others do not:

No access3

  • Small businesses (<500 employees)
  • IP law specialists
  • Patients and their families
  • Alumni
  • Freelancers
  • Citizen scientists
  • Science writers
  • Bloggers
  • Content marketers

DeepDyve’s audience is predominantly unaffiliated with an academic institution. Our biggest single market is that of small businesses:


All these individuals need access to scholarly research and many of them rely on DeepDyve for instant and affordable access to the articles they need. For just $40 per month, they can access 12 million articles:

  • Read as many as they like
  • Print up to 20 pages per month
  • Download PDFs for 20% off
  • 2 week “no obligation” free trial

2014-year-end-preso-v3-2-638Our 2014 report is now available on Slideshare. If you don’t have time to look at the full deck then this slide of highlights should be of interest.

To sum up, in the words of another happy user: “@deepdyve is a fabulous solution to the independent researchers problem of access to information”.

It’s important to also remember that over 50% of more recently published articles are freely available to read and re-use online because their authors chose to publish them Open Access. Savvy information professionals also make full use of these resources.
