Simplifying Access to Paywalled Literature with Mobile Vouchers

Increasingly I read new scientific papers on a mobile device, often at home in the evening when I’m not on my university’s network. Most of the articles I read come from scientists on Twitter, Twitterbots or RSS feeds, which I try to read directly from my Twitter or RSS clients (Tweetbot and Feedly for iOS, respectively). Virtually every day, I hit paywalls trying to read non-open access papers from these sources, which aggravate me, waste my time, and require a variety of workarounds to (legally) access papers that differ depending on the publisher/journal.

For publishers that expose an obvious “Institutional login” option, I will typically try to log in using the UK Federation Shibboleth authentication system, which uses my university credentials. But Tweetbot and Feedly don’t store my Shibboleth user/pass, so for each article I either have to manually enter my user/pass, or open the page in Safari where my Shibboleth user/pass are stored. This app switch breaks my flow and leads to tab proliferation, neither of which are optimal. Some journals that use an institutional login temporarily store my details for around a week so I don’t have to do this every time I read a paper, but I still find myself entering the my details for the same journals over and over.

For journals that don’t have an institutional login option or hide this option from plain view, I tend to switch from Twitter/RSS to my IPad Settings in order to log in to my university VPN. The VPN login on my iPad similarly does not store my password, requiring me to type in my university password over and over. This wouldn’t be such a big deal, but my university’s requirement of including one uppercase Egyptian hieroglyph and one lowercase Celtic rune makes entering my password with the iOS keyboard a hassle.

In going through this frustrating routine yet again today trying to access an article in Genetics, I stumbled on a nice feature that I hadn’t seen before called “Mobile Vouchers” that allows me to avoid this rigmarole in the future. As explained on the Genetics Mobile Voucher FAQ:

A voucher is a code that will tie your mobile device to your institution’s subscriptions. This voucher will grant you access to protected content while not on your institution’s network. Each mobile device must be vouched for individually and vouchers are only valid for the publisher for which it is issued.

Obtaining a voucher is super easy. If you are not on your university network, you first need to be logged into your VPN to obtain a voucher. Once on your university network, just visit, enter your name/email address and then submit. This will issue a voucher that you can use immediately to authenticate your device (it will also email you with this information). Voilà, no paywalls for Genetics on your iPad for the next six months or so. In addition to decreasing frustration and increasing flow for scientists, I can see this technology being really useful for PhD students, postdocs and visiting scientists to retain access to the literature for a few months after the end of their positions.

I was surprised I hadn’t seen this before, since it eliminates one of my chronic annoyances as a consumer of the digital scientific literature. Maybe others would disagree, but I would say that publishers haven’t done a very good job of advertising this very useful feature. Googling around, I didn’t find much on mobile vouchers other than a SlideShare presentation from Highwire press from 2011, which suggests the technology has been around for some time:


I also couldn’t find much information on which journals offer this service, but a few google searches led me to the following list of publishers/journals that offer mobile vouchers. It appears that most of these journals use HighWire press to serve their content, and that vouchers can operate at the publisher (e.g. Oxford University Press) or journal (e.g. Genetics, PNAS) scale. The OUP voucher is particularly useful since it covers Molecular Biology and Evolution and Bioinformatics, which (together with Genetics) are the journals I hit paywalls for most frequently. Since these vouchers do expire eventually, I thought it would be good to bookmark these links for future use and to highlight this very useful tech tip. Links to other publishers and any other information on mobile vouchers would be most welcome in the comments.
