Not to take away from you point or the hard work you put into restoring the Golding series but the Google scanned books can be searched based on their text.
If you choose to download the book you can not search it yourself, only the on-line version and it takes some getting used to the interface. For those interested use the advance search on the Google book page. By filling in the fields in the lower half of the screen you can narrow you search to just a single book, or if so desired a single or multiple topics.
The scanned books are not nearly as clear or easy to read and can not be searched when not on-line. I very much prefer the "rebuild" books. I can only imagine how nice the volume is going to be that DW is currently working on, re-drawn illustrations and all. As Terry suggests, the images are the first to suffer from duplication but often hold the most information.
It is however unrealistic and unfair to expect from DW that he restores any and all books that cover or are of interest to the gentle craft. The scanned books are a nice alternative all be it of a much lesser grade.
DW, I don't know if the ISP has tracked downloads of the currently listed volumes but I see links to the HCC library, where they are hosted all over the Internet. Your efforts are greatly appreciated even if they are not always expressed
