Vertical file

Vertical file is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Vertical file rather than just read about it. In short: A vertical file (sometimes referred to as a clippings file or pamphlet file) is a collection of material, such as correspondence, news clippings, booklets, maps, pictures, pamphlets, tourism brochures, or other grey literature, created and maintained by businesses, libraries and other organizations. The materials are typically loose, separate pieces filed on edge and organized in folders often with tabs or guides an…

Key takeaways

Vertical file belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Vertical file to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Vertical file from memory before moving on to harder problems.

Reference excerpt

A vertical file (sometimes referred to as a clippings file or pamphlet file) is a collection of material, such as correspondence, news clippings, booklets, maps, pictures, pamphlets, tourism brochures, or other grey literature, created and maintained by businesses, libraries and other organizations. The materials are typically loose, separate pieces filed on edge and organized in folders often with tabs or guides and arranged most often alphabetically by subject. Vertical files are used as ready reference material to supplement other collections on topics not easily covered by conventional material such as books. The name comes from the fact that these collections are often stored in the vertical style of filing cabinets (as opposed to the lateral). Prior to the advent of vertical filing, correspondence was often filed in pigeonhole files, spike or spindle files, box files, bellows files, and flat files. The first vertical file was made in 1892 and shown in 1893, at the Chicago World's Fair by the Library Bureau.

Vertical files have been manufactured since at least the early 1900s, however, their use and maintenance have waned in recent years due to the availability of information on the web. The vertical file is related to the picture file, which is a collection of similar nature except that the contents are primarily images.

Worked examples

Example 1 — a first encounter with Vertical file

Start with the simplest possible case. Write down what Vertical file claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Vertical file before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Vertical file ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Vertical file

In research: Vertical file appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Vertical file in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Vertical file is common in secondary-school and first-year university syllabi. It links to neighbouring topics Library and information science stubs, Reference works, so understanding it makes those chapters shorter.
In everyday life: Look for Vertical file outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
