Edited Isys document lists may be exported for uses such as building batch programs to perform actions on selected files. One of the major Isys innovations in the 3.X DOS version was the ability to annotate viewed documents. By the DOS 4.X version, annotations could themselves be indexed and searched. In the Windows 5.0 version, annotations now offer a host of features, including easy creation of hyperlinks among annotations, documents, graphic images, embedded queries for related documents, and user-customized hyperlinks that can launch applications. Annotations are stored as separate files linked to corresponding documents, either in a designated directory or in the same directory as the documents.
Annotations are particularly useful for constructing litigation databases.
Selected text may be sent to the Windows clipboard, gathered and edited in Notepad or WordPad, faxed, E-Mailed, printed, or used to frame another query. The gathering feature is an extremely useful tool for conducting research, for example extracting relevant information from deposition transcripts complete with headers showing file name and location, document title, witness name, document page number, and line number. Isys databases may be as large as two gigabytes containing up to 32 million documents each, and up to 32 databases may be chained to be scanned in a single search, either on the fly or by configuration. Isys also offers a full complement of network administration and security configuration tools, allowing customizing for individual users and monitoring of usage. Selection of documents to be added to a given database is controlled by a range of methods from individual file designation up to rules-based inclusion or exclusion.
