Personal information management (PIM) is the study and implementation of the activities that people perform in order to acquire or create, store, organize, maintain, retrieve, and use informational items such as documents (paper-based and digital), web pages, and email messages for everyday use to complete tasks (work-related or not) and fulfill a person's various roles (as parent, employee, friend, member of community, etc.); it is information management with intrapersonal scope. One ideal of PIM is that people should always have the right information in the right place, in the right form, and of sufficient completeness and quality to meet their current need. Technologies and tools can help so that people spend less time with time-consuming and error-prone clerical activities of PIM (such as looking for and organising information). But tools and technologies can also overwhelm people with too much information leading to information overload. A special focus of PIM concerns how people organize and maintain personal information collections, and methods that can help people in doing so. People may manage information in a variety of settings, for a variety of reasons, and with a variety of types of information. For example, a traditional office worker might manage physical documents in a filing cabinet by placing them in hanging folders organized alphabetically by project name. More recently, this office worker might organize digital documents into the virtual folders of a local, computer-based or into a cloud-based store using a (e.g., Dropbox, Microsoft OneDrive, Google Drive). People manage information in many more private, personal contexts as well. A parent may, for example, collect and organize photographs of their children into a photo album which might be paper-based or digital. PIM considers not only the methods used to store and organize information, but also is concerned with how people retrieve information from their collections for re-use.
