Description of Searchable Fields

Free Text Search

This field allows the user to input any word or series of words, and the database will return all citations containing these word(s). Note that this is an exact string match function only; this version of the search engine does not support boolean AND,OR operations. These word(s) can be from any field contained in the citation (e.g. title, source).

Author

This field allows users to search for citations from a particular author. Users can enter the authors LAST NAME, and all citations containing this name will be extracted from the database. Note that there may be more than one author with the same last name, so some sorting and browsing by the user may be required to find particular citations of interest.

Category

This field allows users to select from one of 8 broadly-defined categories in order to narrow the scope of their search. The first six categories loosely follow the structure of the 1994 United Nations Environment Programme (UNEP) publication "Environmental Effects of Ozone Depletion: 1994 Assessment", while the remaining two categories cover overlapping areas of photobiological research and general overview pieces contained in newspapers or other periodicals. These categories and a list of relevant research fields and topical areas are given in the table below:

CATEGORY	RESEARCH FIELDS/TOPICAL AREAS
Atmospheric Physics and Chemistry	ozone depletion, UV radiation, spectroscopy, dynamics, meteorology, air pollution, radiative transfer, instrumentation, aeronomy, solar physics
Terrestrial Ecosystem Effects	terrestrial plant and animal impacts of UV exposure, photochemistry, photobiology, molecular and cellular biology
Aquatic Ecosystem Effects	aquatic plant and animal impacts of UV exposure, photochemistry, photobiology, molecular and cellular biology
Human Health Effects	skin cancer epidemiology, ophthalmology, immune suppression, photochemistry, photobiology, public health, molecular and cellular biology
Materials Effects	polymer science, material degradation
Biogeochemical Cycle Effects	biogeochemistry, nutrient cycling, biomass burning
Photobiology/Cellular Research	photomedicine, photoimmunology, photodermatology, genetic research, murine experiments, cellular biology
Non-scientific/General reviews	newspaper articles, general reviews, letters to the editor

Source

This field provides a list of all sources of the citations, e.g. journal titles, books, conference proceedings, newspapers, and other periodicals. The user can either select a source of interest or leave this field blank in order to return citations from more than one source if desired.

Year

This field allows the user to select citations from a given year or range of years of interest. Using the radio buttons denoted by the symbols "less than or equal" (<=), "greater than or equal" (>=), or "equal" (=), users can select a range of years from which to search the database (e.g. 1985-1992), or select an open-ended search (e.g. 1993-present; 1985 and previous). These would be entered as the following:
• Single year -- enter year number and select "=" button in the Year #1 field only.
• Range of years (inclusive) -- enter earlier year number and select ">=" button in the Year #1 field, and enter the later year number in the Year #2 field.
• Open-ended search -- for searching all years less than a given year, enter the year in the Year #1 field and select the "<=" button. For searching all years later than a given year, enter the year number in the Year #1 field and select the ">=" button.

Title

This field allows the user to enter the title of a journal article, book, or other publication. This may be particularly useful if the user knows the name of a book, but does not know the editor(s) or author(s) names.
