Notes on Content

Notes common to the "Notes on Content" columns for this website:

Use of parentheses in the following situations:

Below is an explanation of the explicit and implicit anniversaries of the birth and death included in the "Notes on Content" column of the meteorological and climatological contributors pages of this website.

• An explicit anniversary (not in parentheses) is included for a postal item (stamp or associated item such as FDC, maxicard, etc.) that specifically indicates either the anniversary in question (e.g. "200th anniversary of birth") or the first and last years that determine the anniversary span (e.g. "1804 - 2004"). These spans are often multiples of 50 or 100, though other spans, mostly multiples of 10 and 25, also occur.
• An implicit anniversary has no specific indication in the stamp or other associated item. The span will generally be a multiple of 10, and rarely a multiple of 25. These are in parentheses in the "Notes on Content" column.

Use of quotation marks in the following situations:

A phrase in quotation marks in the Notes means that the quoted text as well as a depiction of the element of interest (e.g. a satellite) are found in the philatelic item. If only the quoted text is present in the philatelic item (no depiction), then in the Notes that text is followed by the phrase "in text only" in parentheses. As necessary, other types of explanatory text may also follow the quoted phrase. In some cases, one or more words surrounded by square brackets may appear within the quoted phrase in the Notes. Such text within square brackets does not appear in the philatelic item, but is used in the Notes as explanatory/supplementary information to make them as clear as possible.
