There are now many different products available for collaborative authoring of documents. The choice of which software to use depends on the particular type of authoring task being undertaken and the nature of the group undertaking the tasks. In academic work, the collaborative authoring of papers has become much more common, supported by products such as Microsoft Office, Google Docs or lesser known services such as Wiggio. However, the writing of academic articles is a highly formal and specialised process, thus in there is a need for high-calibre editing, review, citation and versioning mechanisms, especially when more than one or two authors is involved.
Whilst Google Docs was quick-off-the-mark in terms of providing a cloud-based service for the writing and editing of documents by multiple-authors, the service lacked the tools required for the more formal aspects of academic writing (such as structuring long articles, embedded tables and images, and collaborative editing, particularly through tracking-changes to the documents). Many academics settled on the power of Microsoft Word, with its sophisticated editing and track changes functionality, and then simply swapped version of the documents through email or via cloud-based services such as DropBox. This type of collaboration may be effective for thesis writing or small collaborations between say two people, but when more authors are involved it becomes highly inefficient as versioning (manual) becomes problematic as does the ability to locate who is working on what documents at a particular time.
In terms of collaborative authoring, Google Docs and Microsoft have come a long way in the past couple of years; especially in terms of the integration of their services with their respective cloud drives (Google Drive and One Drive). These cloud drives allows for the sharing and storage of documents in one central location (as with DropBox) but with the advantage of having the authoring, editing and review tools built in (ie. Word and Google Docs). Authors can work on the same document at the same time, with the contributions of each author recorded for review by the other authors.
Microsoft Office 365 is the cloud-based version of the familiar Office and offers the Office suite of tools with a large amount of storage (in OneDrive). The cloud version of Word that comes with Office 365 is not as sophisticated as the off-line version of Word, but it is integrated with it and Word documents may be down-loaded if needed. Documents may be worked on collaboratively in real-time, and then down-loaded and refined for submission as a journal article or book chapter. One of the authors, the lead author or the submitting author, could download the Word document from OneDrive, refine it in the offline version of Word, then submit it to a publisher. This is a very effective way of collaboratively authoring papers.
