	Chemical elements data references - Wikipedia, the free encyclopedia
		Recommended values for many properties of the elements, together with various references, are collected on these data pages.
		Any changes to the infobox data should be checked against these pages, and/or the available references should be expanded accordingly, so that the decision for or against certain values remains transparent and easily retraceable.

	MEDLINE, SDILINE and the Backfiles Data Elements and Other Information
		An X in the box indicates that the data element is significantly represented in the database (this is either because the element is defined for all, or nearly all, years of publication found in that database, or because it is simply present on a very large percentage of records for years in use).
		An * in the box indicates that the data element is present on less than 1% of the records in that database (this is primarily due to releveling).
		The data element may be multiply- occurring with a new RO value added each time a record is maintained (except a new occurrence will NOT be added if the initials for the last RO occurrence are the same).

	EPA: Federal Register: Data Elements for Reporting Water Quality Results of Chemical and Microbiological Analytes
		Because of the cost of its collection, water quality data must be viewed as a resource worthy of careful management both to preserve it for future analyses by the agency that collects it and to share it among local, state, and federal agencies, and the private sector involved in resource management activities.
		A data element may be a data field in a database such as a laboratory name, and analyte, or the latitude of the sampling station.
		The list of data elements is not specific to any particular database, but is intended to be used voluntarily by agencies, organizations and individuals to guide their reporting, storage, and sharing of water quality data.
