Care of Books - updated 2 June 2021
We are developing a gallery of bookmarks with advice on how to take care of books. This topic was inspired by the first two examples that also appear in Gallery 4 - Bookmarks on Bookmarks.  They may be from libraries, organizations, or other sources and they may be serious or silly, as long as they have a reminder about good practices such as using a bookmark!  Send your examples to the webmaster.  
Libraries and book related organizations promote good practices in caring for books.
