Writing manuscripts will be a very common activity for many fellows. At the moment we work in a very archaic manner, writing on Microsoft Word and adding citations using a number of different reference management tools (Reference Manager, EndNote, Mendeley and Zotero, etc).
Some of these reference management tools allow for the establishment of group bibliography lists, a particularly good example is Zotero, which has a the Zotero Groups functionality. Zotero is free and open source and cross platform (Windows and Mac friendly). New fellows would do well with using Zotero as a reference manager particularly if they do not have any experience with previous reference management tools.
One big advantage of Zotero is that it now has integration with Google Docs. Two or more fellows working on the same manuscript via Google Docs can potentially edit the same document, eliminating the need for sending out Microsoft Word .docx files with changes tracked back and forth via email. This eliminates problems with version control and furthermore allows for collaborative writing with a commonly maintained group bibliography, thus allowing for all collaborative authors to insert citations without causing disruption to the numbering of references. People familiar with using older reference management tools, like EndNote, would know that they often insert code tags within a .docx file that, if altered, can corrupt and make the reference list formatting completely disrupted.
However, there are some issues with working in this way: after the manuscript draft is agreed and the online submission process needs to take place, one of the authors would have to take the Google Docs document and export this into a format acceptable to the journal. For the BJA and Anaesthesia, this would often be a Microsoft Word .docx file. Furthermore, any images and tables will also need to be separately prepared outside of Google Docs (although lower resolution images can be inserted into the Google Docs document to facilitate visualisation during the writing process).
