Personal digital assistants (PDAs) came next, integrating small liquid crystal displays with a touch-sensitive layer to input graphics and written text.
Tablet PCs are larger and provide more writing and navigation space.
Land surveyors commonly record field notes in durable, hard-bound notebooks called "field books." Coloring enthusiasts use coloring notebooks for stress relief.
The pages in coloring notebooks contain different adult coloring pages.
Inventor's notebooks have page numbers preprinted to support priority claims. Artists often use large notebooks, which include wide spaces of blank paper appropriate for drawing.
Lawyers use rather large notebooks known as legal pads that contain lined paper (often yellow) and are appropriate for use on tables and desks.Making and keeping notebooks was such an important information management technique that children learned how to do it in school. Holley of Holyoke, Massachusetts, invented the legal pad around the year 1888 when he innovated the idea to collect all the sortings, various sort of substandard paper scraps from various factories, and stitch them together in order to sell them as pads at an affordable and fair price. As a solution, he glued together a stack of halved sheets of paper, supported by a sheet of cardboard, creating what he called the "Silver City Writing Tablet".In about 1900, the latter then evolved into the modern legal pad when a local judge requested for a margin to be drawn on the left side of the paper. The only technical requirement for this type of stationery to be considered a true "legal pad" is that it must have margins of 1.25 inches (3.17 centimeters) from the left edge.In the open position, the pages can be removed and rearranged.In the closed position, the pages are kept in order.During the fourteenth and fifteenth centuries notebooks were often made by hand at home by folding pieces of paper in half into gatherings that were then bound at a later date.The pages were blank and every notekeeper had to make ruled lines across the paper. Birchall of Birchalls, a Launceston, Tasmania, Australia-based stationery shop, decided that the cumbersome method of selling writing paper in folded stacks of "quires" (four sheets of paper or parchment folded to form eight leaves) was inefficient.Some styles of sewn bindings allow pages to open flat, while others cause the pages to drape.Variations of notebooks that allow pages to be added, removed, and replaced are bound by rings, rods, or discs.Since the late 20th century, many attempts have been made to integrate the simplicity of a notebook with the editing, searching, and communication capacities of computers through the development of note taking software.Laptop computers began to be called notebooks when they reached a small size in the 1990s, but they did not have any special note-taking ability.
