One can search for an artist by name by visiting artistsignatures.com. The website has options to search for a database of artists by entering the name of the artist and comes up with related results. However, one needs to log in to access full information about the artist.
There are other sites, such as Artcyclopedia and SignatureFinder, which facilitate this type of search. The advantage of using the search feature is that the sites come up with the artists' names even if one enters only a fragment of the name. SignatureFinder also features a useful slider that frames searches within a specified range of dates.
