Detailed information associated with the source voucher specimens may be obtained by visiting the web pages of the corresponding division or by contacting the appropriate curator.

To maintain accuracy in taxonomic nomenclature, the taxonomic names in the GRR database will be periodically cross-checked with names associated with their source voucher specimens in collections where these specimens are archived.

*The GRR is not responsible for the species identifications of the specimens deposited; these determinations are the responsibility of the individual curators and researchers who have provided the material. Ultimately, it is the responsibility of researchers requesting tissue/DNA samples from the GRR to verify the identity of the voucher specimens linked to these samples before publishing results from analyses of these samples.  Likewise, the nomenclature of many groups of animals and plants is unstable; when searching the database for specimens, try searching under possible synonyms for the taxa of interest.
