These books are great resources for anyone interested in plywood manufacturing. To use them, simply open the pages and start reading. You can take notes in a separate notebook if you want to keep track of important information. When handling the books, be gentle because the bindings are loose. Avoid getting the pages wet as it may cause damage. Store the books in a dry and cool place to prevent further tanning of the pages. If you want to clean the covers, use a soft, dry cloth to gently wipe away any dust.
