Abstract
In a search of contact systems among EB-type binaries, the existing photometric observations of ES Lib and AR Boo have been analysed. We find that ES Lib is a semi-detached system, with the primary filling the Roche lobe. AR Boo is instead found to be a contact system, with no lobe overfilling, and with a large temperature difference between the components, but this solution has to be considered as temptative, because of the poor quality of the data and the lack of any spectroscopic information.
