So much of research tends to be a sort of chaotic self-directed learning experience, little nuggets of information coming from many different resources, sometimes with no way to tie them all together. Our lives today are much improved by utility tools and software that go some way in alleviating this problem. One quintessential tool that we will all use at some point in our graduate studies is a reference management software. I use three. Let me tell you why.
I used some downtime at work (read: while training animals for months and months that disappeared into one another) to look at all the major reference management players. I prepared a chart comparing their various features.
Many before me have prepared more exhaustive charts and lists . Reference management systems try to accomplish more than just managing references, so the most important thing to consider before using these helpful charts is which of the many available functions you are likely to use. Ask yourself these helpful questions:
- Do you work on multiple computers/operating systems?
- Do you want to pay for one?
- Do you need it to organize your library and/or citations?
- What software do you use to write?
- Do you need to share your now extensively curated library or citations with others?
The major functions can thus be reduced to reference manager, reference searcher, citation manager, and life easy-maker. I regret to inform you that I have yet to find the one software to rule them all, but I have found a system that works. I found that Mendeley takes care of many of these functions the best. It starts with being available as a stand-alone app for many platforms. This is helpful because I have a Windows PC at work, a Macbook for personal use, an Android tablet and an iPhone. I have Mendeley on all of them and can take any of my portable devices on my travels, to lab meetings, or conferences and have my library on hand. It is free, with some extra features for paying users. The free features are entirely sufficient for my personal use and allow me to have a shared folder with two lab colleagues. Mendeley has a browser bookmarklet that allows me to save PDFs directly to Mendeley’s free 2GB web storage option or my unlimited device storage. I ask it to kindly rename my PDF files when it stores them so that they all look neat and tidy and not ‘sss9320495-4jfkmd-fk-off.pdf’. I use Microsoft Word to do most of my writing, but Mendeley offers support for Open Office and LaTex and where it does not, it offers flexible ways to add citations in a few clicks. Mendeley has a web version as well, where you can search for papers in other members’ libraries and follow other members to get your social media fix. It does not quite hit the spot with free features for collaborations, but this is precisely how they draw in entire labs to pay for the premium features. Mendeley has a decent PDF viewer that allows you to annotate and star while reading. You can search for words, authors, titles, and journals to find the papers you want. It also has a superb indexing system, can extract meta data, finds duplicates to clear, and offers a vast library of citation styles you can personalize or edit.
Another program named Zotero is very similar to Mendeley in all these features (although it only offers 300MB of free web storage) and is open source. I cannot speak for the stability of the standalone app as I have not used it for an extended time but I hear good things. If Mendeley, which has recently been acquired by Elsevier, goes over to the dark side and makes everything premium moving to Zotero would be an almost seamless switch. I did not start with Zotero as they did not have a standalone app at the time I started using reference management software, but they have come a long way since then.
Features I didn’t know I missed in Mendeley, I found in Readcube. If you’ve read a Nature paper, you have at least seen this combination of letters in this context. Nature, and more recently other journals, offer the Readcube PDF viewer, which is the winning feature of this system. Readcube is now a full-fledged reference management software available as a standalone application with beta features being developed as I write this. The PDF viewer has inline references and an automatic supplemental information download. My PDF reading experience has been vastly improved. Now, while reading a paper, I know which article is citation number 30 by letting my mouse hover over it. I also don’t have to find the buried supplementary files on the journal websites; instead, I just click on the ‘Enhance’ button. Readcube is, quite simply, beautiful. Another feature I have advertised regularly is the ‘Recommendations’ feature, which allows Readcube to look through your library and find you relevant literature you may have missed. It has such an impressive algorithm that it beats Pubmed, ScienceDirect and feedly hands down. It has a wonderful citation editor and plugs into Word flawlessly. Its Pro version, however, does not come cheap and offers a lot of the features that Mendeley does for free, like syncing across multiple devices or watching a folder for automatic imports. The way I get around this is by using my third system.
Dropbox. Dropbox is where I store my references. I do a minimum amount of Dropbox gardening by putting all my PDFs in a folder there and asking Mendeley to watch this folder. I also do semi-regular imports on Readcube from the same folder, which Mendeley has helped me keep tidy and organised. Readcube helpfully adds supplemental materials to this folder and Mendeley renames them. Readcube helps me read them and sometimes download more related papers to the same folder. Dropbox makes sure Mendeley watches them on all my devices and so the trapeze act continues. I still continue to check on updates and new software (currently frowning at Paperpile and Flow) because I’ll jump ship the minute something better comes around. That’s how I convince myself I’m still young. Either way, it’s a helpful world out there and you really don’t have to use Endnote.
