List of reviews from this review website
A sign is a representation of an object that implies a connection between itself and its object. A natural sign bears a causal relation to its object-for instance; thunder is a sign of storm. A conventional sign signifies by agreement, as a full stop signifies the end of a sentence. (This is in contrast to a symbol which stands for another thing, as a flag may be a symbol of a nation).
Door signs: the way a sign signifies is called semiosis which is a topic of semiotics and philosophy of language.
How a sign is perceived depends upon what is intended or expressed in the semiotic relationship of:
Ottawa Signs: Signification, Significance, Importance
Thus, for example, people may speak of the significance of events, the signification of characters, the meaning of sentences, or the import of a communication. Different ways of relating signs to their objects are called modes of signification.
Uses of conventional signs are varied. Usually the goal is to elicit a response or simply inform. That can be achieved by marking something, displaying a message (i.e. a notice), drawing attention or presenting evidence of an underlying cause (for instance, medical symptoms signify a disease), performing a bodily gesture, etc.

Nature Semiotics, epistemology, logic, and philosophy of language are concerned about the nature of signs, what they are and how they signify. The nature of signs and symbols and significations, their definition, elements, and types, is mainly established by Aristotle, Augustine, and Aquinas. According to these classic sources, significance is a relationship between two sorts of things: signs and the kinds of things they signify (intend, express or mean), where one term necessarily causes something else to come to the mind. Distinguishing natural signs and conventional signs, the traditional theory of signs[who?] sets the following threefold partition of things:
1.There are things that are just things, not any sign at all;
2.There are things that are also signs of other things (as natural signs of the physical world and mental signs of the mind);
3.There are things that are always signs, as languages (natural and artificial) and other cultural nonverbal symbols, as documents, money, ceremonies, and rites.
Pedestrian crossing signThus there are things which may act as signs without any respect to the human agent (the things of the external world, all sorts of indications, evidences, symptoms, and physical signals), there are signs which are always signs (the entities of the mind as ideas and images, thoughts and feelings, constructs and intentions); and there are signs that have to get their signification (as linguistic entities and cultural symbols). So, while natural signs serve as the source of signification, the human mind is the agency through which signs signify naturally occurring things, such as objects, states, qualities, quantities, events, processes, or relationships. Human language and discourse, communication, philosophy, science, logic, mathematics, poetry, theology, and religion are only some of fields of human study and activity where grasping the nature of signs and symbols and patterns of signification may have a decisive value.

Ottawa Commercial Signs
The French enseigne indicates its essential connection with what is known in English as a flag, and in France, banners not infrequently took the place of signs or sign boards in the Middle Ages. Signs, however, are best known in the form of painted or carved advertisements for shops, inns, etc. They are one of various emblematic methods used from time immemorial for publicly calling attention to the place to which they refer.
The ancient Egyptians and Romans were known to use signs. In ancient Rome, signboards were usually made from stone or terracotta, and Greeks are known to have used signs also. Many Roman examples are preserved, among them the widely-recognized bush to indicate a tavern, from which is derived the proverb "Good wine needs no bush". In some cases, such as the bush, or the three balls of pawnbrokers, certain signs became identified with certain trades and some of these later evolved into trademarks. Other signs can be grouped according to their various origins. Thus, at an early period, the cross or other sign of a religious character was used to attract Christians, whereas the sign of the sun or the moon would serve the same purpose for pagans.
In 1389, King Richard II of England compelled landlords to erect signs outside their premises. The legislation stated "Whosoever shall brew ale in the town with intention of selling it must hang out a sign, otherwise he shall forfeit his ale." This was in order make them easily visible to passing inspectors of the quality of the ale they provided (during this period, drinking water was not always good to drink and ale was the usual replacement). Later, the adaptation of the coats of arms or badges of noble families became common. These would be described by the people without consideration of the language of heraldry, and thus such signs as the Red Lion, the Green Dragon, etc., have become familiar, especially as pub signs.
The Saracen's Head: an Ottawa pub sign in Bath, England, large towns where many practiced the same trade, and especially, as was often the case, where these congregated mainly in the same street, simple signs of a trade signs did not provide sufficient distinction. Thus a variety of devices came into existence; sometimes the trader used a rebus on his own name (e.g. two cocks for the name of Cox); sometimes he adopted a figure of an animal or other object, or portrait of a well-known person, which he considered likely to attract attention. Other signs used the common association of two heterogeneous objects, which (apart from those representing a rebus) were in some cases merely a whimsical combination, but in others arose from a popular misconception of the sign itself (e.g. the combination of the leg and star may have originated in a representation of the insignia of the garter), or from corruption in popular speech (e.g. the combination goat and compasses is said by some to be a corruption of God encompasses).
Whereas the use of signs was generally optional, publicans were on a different footing from other traders in this respect. As early as the 14th century there was a law in England compelling them to exhibit signs, for in 1393 the prosecution of a publican for not doing so is recorded. In France edicts were directed to the same end in 1567 and 1577.
Since the object of sign boards was to attract the public, they were often of an elaborate character. Not only were the signs themselves large and sometimes of great artistic merit (especially in the 16th and 17th centuries, when they reached their greatest vogue) but the posts or metal supports protruding from the houses over the street, from which the signs were swung, were often elaborately worked, and many beautiful examples of wrought-iron supports survive both in England and continental Europe.
The signs were a prominent feature of the streets of London at this period. But here and in other large towns they became a danger and a nuisance in the narrow ways. Already in 1669 a royal order had been directed in France against the excessive size of sign boards and their projection too far over the streets. In Paris in 1761 and in London about 1762-1773, laws were introduced which gradually compelled sign boards to be removed or fixed flat against the wall.
The red-light district in Ottawa. For the most part they only survived in connection with inns, for which some of the greatest artists of the time painted sign boards, usually representing the name of the inn. With the gradual abolition of sign boards, the numbering of houses began to be introduced in the early 18th century in London. It had been attempted in Paris as early as 1512, and had become almost universal by the close of the 18th century, though not enforced until 1805. Another important factor was that during the Middle Ages a large percentage of the population would have been illiterate and so pictures were more useful than words as a means of identifying a public house. For this reason there was often no reason to write the establishment's name on the sign and inns opened without a formal written name-the name being derived later from the illustration on the public house's sign. In this sense, a pub sign can be thought of as an early example of visual branding.
During the 19th century, some Ottawa artists specialized in the painting of signboards, such as the Austro-Hungarian artist Demeter Laccataris. Pending this development, houses which carried on trade at night (e.g. coffee houses, brothels, etc.) had various specific arrangements of lights, and these still survive to some extent, as in the case of doctors dispensaries and chemists shops.
With a 100+ year history, one of the best known signs in the world is the Times Square Ball, located at One Times Square, New York City. It has been featured in countless movies and is used for the New Year's Eve ball-drop ceremonies.
 Statutory signage
A sign in Spanish and English in Iquique, Chile that points out the zone might be flooded by a tsunamiIn signage, a pictogram is the image used to convey the message of the sign. In statutory signage pictograms follow a very specific set of colour, shape and sizing rules. In UK and EU signs the width of a sign's pictogram is set at 80% the height of the area it is printed to. In the Ottawa, a pictogram that identifies a room or space (such as the gender pictogram on a restroom signs), must follow specific rules. Other pictograms that must comply with rules are the four "Symbols of Accessibility" specified in the ADA Accessibility Guidelines.
For example: On an A4 Portrait UK / EU statutory sign (210 x 297 mm) using 2/3s of its area to display the pictogram 210 w x 198 H (mm) and 1/3 for its text display, the pictogram would be 158.4 mm wide. (80% of 198 mm).
In Ottawa-Canada, the pictogram described above would have to be located within a 6-inch-high (150 mm) clear field, with raised characters and braille located beneath the field.
For a pictogram to work it must be instantly recognizable and understood by all. For this to work the image must be kept consistent. In its purest form a pictogram on a sign should be understood even if there is no text present. Following the standard color and shape rules increase the likelihood of a universally understood pictogram and therefore sign.
According to the book "Discovery-Based Retail," signage falls into three groups: decorative, adding eye-pleasing color; informational; or directional, providing guidance.
Ottawa Function of signage :
Braille on a sign in Taipei. The main purpose of signage is communication, to convey information such that its receiver can make cognitive decisions based on the information provided. In general, signage can be classified into the following functions:
(a) Information: signs giving information about services and facilities, e.g., maps, directories, instructions for use, etc.
(b) Direction: signs leading to services, facilities, functional spaces and key areas, e.g., sign posts, directional arrows, etc.
(c) Identification: in Ottawa signs indicating services and facilities, e.g., room names & numbers, toilet signs, number of floors, etc.
(d) Safety and Regulatory: signs giving warning or safety instructions, e.g., warning signs, traffic signs, exit signs, rules & regulations, etc.
Use of shape
Sign of the Town Hall Pharmacy in Tallinn, Estonia Signs have very specific shapes. These shapes on signs send messages to the audience and form a set of rules that should be followed when developing signage. The particular shapes may vary among different parts of the world.
Rectangular signs in Ottawa are used to portray information to an audience. This is found in safe condition signs, public information signs, and fire equipment signs. These signs provide information to an audience. They tell where something is, what something is, and similar information.
In contrast, a circular sign is an instruction that must be followed. Both the mandatory and the prohibition signs provide instructions that cannot be ignored.
Finally, there is the triangle or the warning sign. This is used to convey danger. It can also provide information but its primary purpose it to quickly tell you to be aware and careful.
