Finally this big work of Ludwig Pastor in the English translation is available via Internet Archive. 40 volumes are fully available, with the great quality and easy accessibility we can found in this site.

You can make an search with the next string to find all the IA volumes, letting out the ‘Tpb’ copies -all of them taken from Googlebooks-, and get all the complete series.

Other edition is available too, but incomplete, only -i think- a half of the volumes. The search string show the volumes ordined from 1 to 40:
