Library Postcards [librarypostcards.blogspot.com] has been under active development since 2008. The site is maintained by Associate Prof. Mark Jackson, professional librarian. As of January 2018 there are over 2,500 postcards listed on the site. Each card has associated tags or keywords, including the name of the library, city or town, state or country of location. Whenever historical information is available, it is included. Comments and updates are always welcome.
