The cost of storing it is dropping several times as quickly as pg is adding to it. In the formats they are provided the amount of space saved is I would think negligible by zipping them. And perhaps the detailed description of the required format could be reconsidered. The document to me is written to optimize the preferences of pg at one point in time without much consideration for user effort required. wouldn't you get better compliance and more images if you just asked for what they have preferably with file names derived from page numbers?

The individual files are more valuable if one wants to check a possible error, since one does not need to download the full zip file, just to look at one page. Your images are 20 MB; assuming that this is representative of the collection, all the 40000 books could fit in one disk of 1 TB. The last time that I bought a pocket one, it costed me 90 Euro, so probably PG can afford two to keep the whole collection zipped and unzipped. But a few years ago, when they started to keep page images it costed much more.
