Query the HISTMAG Database:

HISTMAG database combines historical and archeo-/paleomagnetic records of the geomagnetic field.
Historical data were either newly acquired or collected from available publications (e.g., Jonkers et al. (2003), Korte et al. (2009), etc.). Archeomagnetic and lava records were directly integrated from GEOMAGIA50.v3 database (Brown et al., 2015).
See the paper (Arneitz et al., 2017) and manual for details. Please report any problems to Diese E-Mail-Adresse ist vor Spambots geschützt! Zur Anzeige muss JavaScript eingeschaltet sein.. The HISTMAG project was funded by the Austrian Science Fund (P24722).

Updates February 2021:

Several historical datasets have been revised and corrected according to original sources (see log-file). Recent archeomagnetic studies from GEOMAGIA50.v3.4 (from September 2020) and Schnepp et al. (2020) have been added.

2. Query constraints

Obligatory: Choose between 2.a Keyword Query OR 2.b Systematic query:

(The specification of a keyword or selection of a source/material is obligatory; otherwise, no data will be returned)

	2.a Keyword Query

(Information on source, site, comment, observer and literature is scanned for matches.)

Keyword(s) for query (minimum word length is 4 characters):

Advanced search criteria:

Exclude secondary references from search

Search is performed in boolean mode. Operators can be used to improve the query; a few examples are listed below (see the MySQL Reference Manual for complete list of operators):

Operator	Explanation	Example
	no operator	Humboldt Moscow -> Results will contain records which have at least one match; record(s) containing both keywords will appear at the top due to the highest relevance
+	preceding plus indicates that the word MUST be present	+Humboldt +Moscow -> only records containing both keywords will be displayed
-	preceding minus indicates that the word MUST NOT be present	+Humboldt -Moscow -> all records containing first keyword, except those also containing second keyword, will be displayed
