Probably one of the best annotated and curated resource of transcription factor binding preferences (sites and motifs). The free version (v7.0) is very limited and outdated (year 2005). If you want to have online access to the last version, the academic price is more than 1000$. There are other open access databases that can be considered before paying that price.
