Where the World Gathers to Celebrate Every Day


LIBRARY SHELFIE DAY – Fourth Wednesday in January


The fourth Wednesday in January offers a unique opportunity for book lovers on Library Shelfie Day.

Some collectors of books tend to arrange their collections so their spines can be admired pleasantly. Others have a system of organization that results in an alternative art form. However our books are organized on the shelf, they are meant to be photographed and shared on social media.

Library Shelfies offer book stores, libraries, schools, and individuals an opportunity to express their reading preferences through a single photograph. Whether they frame their favorite authors, titles, genres or cover art, readers share a bit of their library in creative ways. With or without dust jackets, signed and unsigned, dogeared and in mint condition, bibliophiles love books of all kinds.

HOW TO OBSERVE #LibraryShelfieDay

Whether you have a small library with a few select favorites or are a true bibliophile, arrange your collection on a shelf and take a picture. Express your inner artist! Build a tower of babbling books or a wall of words. Invite others to join you in your aesthetically pleasing book building adventure. Some suggestions include:

  • Arrange by color
  • Order books by height, thickness, width
  • Arrange book titles so they send a message
  • Stack books artistically
  • Place books in the order in which they were read
  • Rely on the good ol’ alphabetical order by author
  • Display a biography only shelfie

Once you’ve taken your library shelfie, visit a local library and check out theirs. You might find they’ve developed clever ways to entice you to new books and old ones, too. Have fun displaying your collection in fun ways! Don’t forget to use #LibraryShelfieDay to share on social media.

The New York Public Library founded Library Shelfie Day as a way to observe various national holidays by displaying shelfies representing books from each day.NATIONAL CHOCOLATE CAKE DAY – January 27



National Chocolate Cake Day celebrates the cake more people favor. And more often than not, we celebrate our special occasions like anniversaries, birthdays and weddings with cake. Why not enjoy chocolate cake on January 27th every year?

In America, chocolate was consumed primarily as a beverage until the 1830s or 40s. Chocolate cakes, as we think of them today, mostly did not exist then.  According to the Dover Post, the chocolate cake was born in 1765 when a doctor and a chocolate maker teamed up in an old mill.  They ground up cocoa beans between huge millstones to make a thick syrup. The liquid was poured into molds shaped like cakes, which were meant to be transformed into a beverage.

A popular Philadelphia cookbook author, Eliza Leslie, published the earliest chocolate cake recipe in 1847 in The Lady’s Receipt Book.  Unlike chocolate cakes we know today, this recipe used chopped chocolate.  Other cooks of the time such as Sarah Tyson Rorer and Maria Parloa all made contributions to the development of the chocolate cake and were prolific authors of cookbooks.

The first boxed cake mix was created by a company called O. Duff and Sons in the late 1920s. Betty Crocker released their first dry cake mixes in 1947.

HOW TO OBSERVE #ChocolateCakeDay

When it comes to food holidays, we know how to celebrate. This one is no different. Have some cake. Share it with someone else. Visit your favorite bakery and give them some credit, too. Or, if you have some mean baking skills, show them off! We want to see them, too. That means, share your recipes, take some pictures, make a video and show off those delicious, chocolatey cakes! We love how you celebrate these days, so celebrate them with us!
