Grabbing books to give Oranians, Ezra made sure to specially focus on any that involved invention, such as basic engineering, engineering for beginners, magic engineering for dummies, best farming techniques in bad climate and so on and so forth.
Along the lines, he soon discovered that he couldn't find the continuation for such books, and upon asking the attendant, it turned out that those ones were placed in separate sections.
Heading there, he met rows and rows of books aligned on large shelves. This subsection was big enough to be a separate bookstore.
Putting his brain to use, Ezra simply requested that the attendant add three copies of every educational book in the bookstore to his shopping list and make sure it was in hardcopy.
Whilst that was arranged, Ezra browsed other subsections, to secure a few more things.
