It follows from this that the low score in the image availability section is what catches the eye, leaving Bing Maps with one of the lowest scores of the study in that section. 4.4.1. Evaluation of the information available about Spain according to the international sources evaluation system With the information that is available on the basis of the mean OPAC vales for each tool, we will state a pair of characters corresponding to the two scales of the international sources evaluation system (reliability of the source, which will remain constant as this is a generic value of each tool, and represents the credibility of the content) in the same way as has been done above for the rest of the countries.
