The purpose of this article is to evaluate and select websites in Polish book sector with regard to quality measured by their usefulness for an individual client.

Applying both groups of methods in the assessment of bookselling websites appear to have brought about satisfactory results. The findings enabled the author to establish the order of the most popular bookselling websites with regard to the identified criteria groups and the specified subcriteria. The author also considered both qualitative and quantitative criteria. The applied methods allowed for indicating unequivocal and comparable positions in the ranking that concludes experts assessments. Due to the differences in the methodologies and the procedure for calculations, the author has applied additional assumptions rationalizing the methods and increasing the probability of results. The obtained results are different because of applying various evaluation scales and entirely different references in criteria relations. Nevertheless, they allow for creating independent rankings taking into consideration very different preliminary research assumptions (linear scale versus relational scale). It demonstrates that their usefulness in this kind of study has been confirmed. However, both of these methods have their advantages and disadvantages.
Advantages of scoring (ranking) methods are primarily: an easy and user-
In the conducted research the following advantages of the AHP method have been identified: the assumed relativism of evaluation criteria and realisation of the criteria in particular websites; relative elasticity in relation to various classes of objects and a possibility of ordering decision variants in respect of synthetic criteria. There appeared a number of doubts concerning its practical application in relation to quality assessment of internet bookshops. These were: a large degree of evaluations subjectivity, similarly to the case of scoring methods; considerable difficulties experienced by interviewers and experts in the case of application of the relational method, especially when the number of criteria and subcriteria turns out to be a two-
In each case the basic aim of the research was to establish the order of internet bookshops websites with regard to the applied quality criteria group. In both cases end users were interested mainly in a websites functionality and economical aspects. Both groups of methods allow for various analyses of statistical data and practical solutions pertaining to websites. The discovered imperfection of procedures induces the author to look for more effective ranking methods, free of the defects specified in this paper.
