I am starting a book with academic purposes, and I intend to choose a reference manager to handle the citations. The citations are in footnotes (which is kind of tricky for a reference management software) and very specific (the most common citation styles will not cut it).
This is expected to be some sort of long term engagement, since the book may have to be updated from time to time. So, I need a reference manager that keeps being updated over time, and that may fulfill my needs over the years.
As the book is expected to have more than 1,000 citations, the software must be fast, respond fast, and not be buggy.
Also, I plan to use Windows (or OS X) and Microsoft Word. Sometimes I may use the iPad or even the iPhone to type some text (I know I probably will not be able to insert citations in these devices, but at least I do not want to lose the citations I have already inserted). I am definitely not using Linux, and probably not using LibreOffice.org or any other word processor for the task.
My main contenders so far are Endnote, Zotero and Mendeley. I am not considering other reference managers because I think these three are the most popular. My concern here is that I do not want to start using a reference manager that may be discontinued within the next 5 years because it had poor sales or because the company behind it is facing financial difficulties.
I have a copy of Endnote X7 and I may well upgrade it to Endnote X8 if it is worth it. Endnote seems to be solid, but development seems to be slow. I did not see much progress in Endnote in the last few years. I used Endnote for my PhD thesis and it was very slow in updating using the cite-while-you-write feature. In addition, some references got messed up when I accidentally replaced the library for an older version (it relies on the number of the reference instead of the name of author). Endnote was also poor to get references from Google Scholar. On the plus side, it was quite easy to customize styles in Endnote. Now Endnote is not under Thomson Reuters anymore, but under a company called Clarivate Analytics (some sort of spin-off). I do not know what this will represent for future development of Endnote, though.
I have also used Zotero, and it seems to be a good alternative, but I did not use it extensively. The Word plug-in seems very nice. It even insert citations directly in footnotes, so I do not have to insert the footnote and then the citation (which is the case with Endnote and Mendeley). However, I do not know about its speed and whether it is possible to convert the formatted citations to fields to make it faster if necessary. Development seems to be not so fast either (although not so sluggish as Endnote). One of my concerns is that it is run by a university and not a private company. Will it have funds to compete with the big guys in the future? Or will it be swallowed?
I have also used Mendeley. Mendeley started as being a poor alternative, but I am impressed at its development. The interface seems very good, and even better than the contenders. The Word plug-in seems very nice at this point, and it was even able to convert Zotero references into Mendeley references. The Mendeley website is also more visited than Zotero and Endnote websites, according to Alexa (these are #2 and #3 respectively). Mendeley was purchased by Elsevier, and it may be good having a rich parent to support it. But is it fast and flexible?
Now, which one should I go with? Or should I choose another one? I want a reference manager that is good, fast and straightforward, and that is updated at a fast pace and does not fall behind the others or get discontinued. And, if possible, that allows me to convert the citations to another format so I can use it with another reference manager if I need it to.
Thanks a lot.
