The Web contains more and more virtual museum collections, which should consider user needs, demands and desires and follow trends. Studies show under-evaluation of collections and their interfaces. User success at work with information retrieval systems is highly dependent on its interface. If it is user friendly, meeting information needs will reach maximum success. The aim of the study is to evaluate the interfaces of virtual museum collections, with an emphasis on Google Art Project interface (further: GAP). To determine (non)presence of necessary functionalities within GAP interface we used expert study with designed evaluation framework. It contained the following evaluation criteria of interface: search options, navigation, help assistance and personal settings. To study the work with other interfaces or harder perceptual problems, user success and user-friendliness of interaces we used method of scenarios. We developed three scenarios for typical users of virtual museum collections and realized them on interfaces. Both methods were used to determine the fulfilment of recommendations for designing good interfaces. The survey showed that GAP interface contains features which contribute to good user friendliness and user success and also follows contemporary trends. The best represented segment of interface GAP are personal settings segment, followed by search options and help assistance. The most problems were caused by navigation segment to unexperienced users. Analysis of working with interfaces showed maximum success and great user friendliness for experienced users, while these ratios were lower for unexperienced users. In this regard, there is a lack of compliance with rules for good interface design.
