History[ edit ] Palm leaf manuscripts were written in ink on rectangular cut and cured palm leaf sheet. Each sheet typically had a hole through which a string could pass through, and with these the sheets were tied together with a string to bind like a book. A palm leaf text thus created would typically last between a few decades and about years before it decayed due to dampness, insect activity, mold and fragility. Thus the document had to be copied onto new sets of dried palm leaves.
Description[ edit ] "Loose leaf" really describes any kind of paper or book that is available in single sheets, unbound. Its "leaves", or sheets, are "loose" and not bound in notebook or book form.
However, it seems "loose leaf" in the USA and this entry refers most specifically to a lined and punched paper school supply also known as "binder paper" that can be sorted in a loose leaf binder. This may be a typical 3 ring binder but "loose leaves" of other types can also go in a date book, address book or artist's portfolio, additionally there are also loose leaf textbooks.
There are three common types of binder paper: College ruled paper has less space between the blue lines, allowing for more rows of writing. Wide ruled paper is intended for use by grade school children and those with larger handwriting.
The chief advantage of loose-leaf paper is its flexibility and economy in use. A punched sheet of paper can be inserted into a ring binder, removed for separate use, and then returned to the binder.
Different sheets can be organized into a different order in a binder, or removed entirely and refiled in another binder, or disposed of as needed. This ability to rearrange and update the contents of binders is convenient for students and others, who can carry only the papers they are likely to need on a given day, while leaving the remainder elsewhere.
The ability to add or remove an arbitrary number of pages has been useful for reference works that are frequently updated, such as computer software manuals, parts catalogs, and legal indexes.
Or it need not be bound at all and can stand on its own as a single paper.
The chief disadvantage of loose-leaf paper is that individual pages can be easily removed or lost from its storage binder due to tearing or wear of the punched holes. Adhesive reinforcement labels or sheet protectors are available to make pages more durable, and ring binders are often equipped with sheet lifters or other features to reduce wear and damage to their paper contents.
Ring binders are sometimes banned from use for written journals, logs, or registers, which may even have pre-numbered permanently bound pages to discourage removal of pages, or at least allow a removal to be detected.
