the technological development of cloud storage allows contemporary copy editors and writers to upload and share files across multiple devices. online word processors such as google docs, dropbox, zoho, opengoo and buzzword allow users to perform a number of tasks. each processor has its advantages and disadvantages based on the users' preferences, but primarily allows users to share, edit and collaborate on documents. on google docs users can invite others via email to view, comment, and edit any file of their choosing. those invited can view and edit the document together in real time. unlike google docs whose files can only be shared through the web app, dropbox shares from a desktop app. dropbox users can share documents as links or as shared folders. users can create shared folders and add others to the folder. files in a shared folder will appear in the other user's dropbox and all involved users receive notifications when edits are made to a file in the folder. adobe's buzzword allows users to share files, with the user's choice from varying levels of editing access, and includes a version history feature which tracks changes made to documents and lets users revert to earlier versions.
