Talk about wide circulation.

The Toronto Public Library is giving a shout-out to its northern counterparts after a librarian sent home a book that was mistakenly returned in Yellowknife.

The TPL posted to social media this week a photo of one of their books with an affixed note, saying that the book had been dropped off “here in Yellowknife. Just thought it might like to go home!”

Librarians really are the best :) Thanks @OurYellowknife ! The book came back home safely! #TravellingBooks pic.twitter.com/wxkeiL0etm — TorontoPublicLibrary (@torontolibrary) April 14, 2016

TPL also appeased curious readers who wanted to know what book it was, posting a photo of the book without the note – turns out the book that journeyed to the north was a guide on German idioms.

Katy Harmer, a library assistant at the Yellowknife Public Library, sent the book back to Toronto with the friendly note. In a phone interview, Harmer said that, when she receives books “that don’t belong in our library,” she’s responsible for getting them home. “I’m happy to get it back to where it’s supposed to be,” Harmer said.

TPL spokesperson Ana-Maria Critchley said the gesture “shows you the lengths that librarians will go to make sure that books get into the right hands.”

It’s not the first time books have been dropped off in other jurisdictions, just to be returned home, Critchley added.

“There are quite a few stories of getting books from a different system.”

Critchley said TPL will sometimes receive drop-offs from University of Toronto libraries, and vice versa.

The note has been received warmly by book lovers, with the photo being shared hundreds of times over Facebook.

“It illustrates in a really simple, relatable way, how important books are in individuals’ lives, and it just brings a smile,” Critchley said. “So I’m not surprise that people are responding warmly to it.”

Harmer said she “didn’t think anything of” sending the book back, and only found out that it was being shared via social media from her brother, who saw it on Facebook.

The book is now back in circulation in Toronto’s public library system.
