Knowledge will assist in determining the direction an art collection should take. A well-established collection first and foremost should be in accordance with personal taste; nevertheless, an art collection can focus on a specific medium, style, genre, etc. A collection of figure drawings will have more value as a collection since there is a cohesive subject matter and medium. A collection that features realism as an artistic style could possibly consist of a major painting or two and a mix of smaller renderings in varying sizes. Establishing certain criteria for collecting will benefit the collection as much as understanding art.
