These books are great for anyone interested in Mary Baker Eddy's works. You can read them at your own pace, just like any other book. When handling, make sure your hands are clean to avoid adding more soiling to the covers. Since the covers are in a bit of rough condition, especially 'The First Church of Christ Scientist and Miscellany' with chipping and scuffing at the hinges, be gentle when opening and closing the books. If you want to preserve them for a long time, store them in a dry place away from direct sunlight. Don't write on the pages to keep them clean as they are now. And when you come across the out - of - order pages in 'Science and Health', you can take your time to understand the flow of the text as they do appear in order later.
