Scheduled downtime on Tuesday for some of Mendeley Web

[UPDATE 2:42pm: all services are back up and running as usual.]

The growth in researchers discovering and using Mendeley continues to humble us. We have outgrown what our current data center can provide, so now we are expanding into a new one. Unfortunately, this means that some services will be put on hold while we make these upgrades.

Services that may experience downtime starting at 1:30 am PST (9:30 am BST) on Tuesday, July 13 are search and article pages. We anticipate that these will be unavailable for two to six hours.

Client syncs or uploading metadata to Mendeley will NOT be affected during this upgrade.

From all of us, thank you for using Mendeley and changing how research is done.

Reminder – Mendeley ‘Open Office’ this Friday!

This is just a quick reminder of our ‘Open Office’ event this coming Friday 18 Sept from 5pm onwards – in case you haven’t seen our previous blog post from last week: we’d like to invite London users to come in to our office and chat to us directly in order to share their general feedback and their suggestions as to what they’d like to see improved in Mendeley. Drinks and snacks will be provided.

If you’re interested in coming along, please email

We’re looking forward to seeing you!

Mendeley invites you to ‘Open Office Friday’

Since we are getting closer to releasing version 1.0, we were discussing how to get even more detailed feedback from our users than we currently get through our support system.

Being able to chat with you guys face-to-face would obviously be best so we said: lets try it and do an ‘Open Office Feedback Session’. Meaning that everyone who is interested can drop in to our offices in Clerkenwell and talk to different members of the team and tell us face-to-face what you like to see improved or added to Mendeley. You can also bring your notebooks and show us directly what’s not working for you or which feature you would like to do differently.

Mendeley office

Your feedback is very valuable to us so as a thank you we would serve drinks and snacks at our office which we could even have on our roof terrace if the weather will allow it, probably not – lets face it :).

If you’re interested, please drop us an email at We’re looking forward to meeting you!

Improved Google Scholar lookup

Just a quick update: the Google Scholar lookup in Mendeley Desktop will now return improved document details. We’ll continue to work on improving this but if you have got any suggestions let us know and we’ll look into it.

As for other updates we are currently testing a portable Windows version of Mendeley Desktop which we’re hoping to release this week. We are also planning to finish all “behind the scenes” work for the next major release this week as well. More bug-fixing is needed though so the next version will probably be out around mid September.

And the winner is… Jonathan Peelle!

Last month, we decided to reward loyal referrers who invited at least 3 colleagues via the Mendeley invite tool and entered them into a prize draw to win an ipod shuffle.

Last week we’ve randomly drawn the winner and it is…. Jonathan Peelle from Cambridge University! He is a postdoctoral fellow at the MRC Cognition and Brain Sciences Unit researching speech and language processing in the human brain.

Here’s what he thinks about Mendeley:

Jonathan Peelle“There are three things that drew me to Mendeley. The first was the combination of desktop software and the web interface both of which are excellent and support the way I work. In particular having the web interface means my library is always accessible, wherever I am.

Second, the ability to share papers with co-workers is fantastic. It enables me to see what my colleagues are reading and saves me the trouble of typing in or searching for references they have.

Finally, being able to organize my articles by topic/folder and tags is very handy, and helps me to find those slightly more obscure references I’ve read and filed but then promptly forgotten.”

A big thank you to Jonathan and all other loyal users for spreading the word about Mendeley!

2 new full-time Mendeleyans

We are happy to announce two new members of the Mendeley family. While Carles Pina adds some Spanish flavour to Mendeley Desktop, Nicholas Jones increments the Southampton University headcount to three by bringing some award-winning expertise to the Mendeley Web table. In their own words:

Carles PinaCarles Pina is a software engineer at Mendeley. He studied computer engineering at La Salle – Ramon Llull University in Barcelona and thought working for Mendeley is a perfect reason to relocate to rainy London. Well, after growing up near Barcelona most cities feel ‘rainy’ he thinks.
In his spare time, he enjoys programming in C, Python or C++ maintaining projects like qdacco or contributing to other free software projects. He is also fascinated by attending computer meetings in general and loves traveling.
Nicholas JonesNicholas Jones is a software engineer for Mendeley Web. He studied Computer Science at the University of Southampton, graduating with a BSc in 2009. Whilst at the University of Southampton he won the Sir William Siemens Prize for “excellence and innovation on an individual 3rd year project” and the Netcraft Prize for acedemic acheivements in his 2nd year.
When not coding away at PHP and JavaScript, Nicholas enjoys trawling through social news sites such as Reddit, looking for interesting and invigorating items to read. Nicholas also has a keen interest in music and when not listening to it, may be found strumming away at his guitar.
