Jaime,
I found the book fairly easy to read for a non Spanish speaking person. The pictures are good and there are some great list of port actions during the late 19th Century. Maps run good to rather crude for some of the locations, but for the most parts they give enough detail that it is possible to figure out where the port may be located in relation to other towns.
Down load was over 60 MB but in the modern computer that is a very small part of the normal hard drive.
Thanks for letting us know about this interesting book.
