Any errors in OTT should be assumed to have been introduced by the Open Tree of Life project until confirmed as originating in the source taxonomy.
Download locations are for the particular versions used to construct OTT 3.0. For new work, current versions of these sources should be retrieved.
Curated additions from the Open Tree amendments-1 repository as processed into https://github.com/OpenTreeOfLife/edOTTs up to commit 1281c6afa4fa504af4b2f47d9965d16f6e1067d6 These taxa are added during OTU mapping using the curator application.

Taxon identifiers are carried over from OTT 3.1 when possible
It has been requested that we relay the following statement:
The Open Tree Taxonomy does not reproduce its sources in their entirety or in their original form of expression, but only uses limited information expressed in them. See "Scientific names of organisms: attribution, rights, and licensing" (http://dx.doi.org/10.1186/1756-0500-7-79) regarding use of taxonomic information and attribution.
Where taxonomies conflict regarding taxon relationships, they are resolved in favor of the higher priority taxonomy. The priority ordering is as given above, with the following exceptions:
The non-Fungi content of Index Fungorum is separated from the Fungi content and given a priority lower than NCBI and GBIF.
The non-Malacostraca, non-Ctenophora content of WoRMS is separated from the Malacostraca and Ctenophora content and given a priority lower than NCBI but higher than GBIF.
