'Bielefeld' Academic Search Engine ('BASE') Client

Interface to the API for the 'Bielefeld' Academic Search Engine ('BASE') (< https://www.base-search.net/>). 'BASE' is a search engine for more than 150 million scholarly documents from more than 7000 sources. Methods are provided for searching for documents, as well as getting information on higher level groupings of documents: collections and repositories within collections. Search includes faceting, so you can get a high level overview of number of documents across a given variable (e.g., year). 'BASE' asks users to respect a rate limit, but does not enforce it themselves; we enforce that rate limit.

The 'Open Tree of Life' aims at assembling a comprehensive phylogenetic tree for all named species.
