NoteTab is a text and HTML editor for MS Windows. There are three different versions: NoteTab Light, which can be downloaded for free, NoteTab Standard, which includes special features not available in the free version, and NoteTab Pro, which the Whitman Archive recommends. NoteTab Pro is installed on all computers in the two Archive offices.

NoteTab Pro also enables end-users to maximize "find-and-replace" (FaP) capabilities with the use of regular-expressions (RegEx). While helpful, it should be noted that large-scale FaPs using RegExs have a tendency to use a large amount, if not all of, NoteTab Pro's memory that results in deletion of the entire document; if you create and implement them, make sure to upload a recent version of your document to the server so you an unaffected back-up file.
