Have you seen Charles Darwin's missing notebooks? If so, the authorities 鈥� and some "heartbroken" librarians 鈥� would like to have a word with you.
That's the bottom line of an appeal by Cambridge University Library in the United Kingdom. The library, which manages a of the famed naturalist's work, said it's seeking two notebooks that have been missing for nearly two decades 鈥� and that, after an exhaustive search, they fear were stolen.
Cambridgeshire police that they have opened a formal investigation into the disappearance. The library says the pair of journals, which it estimates being worth millions of dollars, have also been added to the in the U.K. and Interpol's .
"It is deeply regretful to me that these notebooks remain missing despite numerous widescale searches over the past 20 years, including the largest search in the library's history earlier this year," Jessica Gardner, the Cambridge University librarian, said in a recorded .
"We would be hugely grateful for anyone with information that might assist in their recovery," she added. "Someone, somewhere may be able to help us return these notebooks to their proper place at the heart of the U.K.'s cultural and scientific heritage."
Among the missing papers is a sketch that Darwin composed in 1837, shortly after returning from the voyage on the HMS Beagle that helped inspire his theory of evolution. , better known among scholars as the Tree of Life sketch, reveals elements of Darwin's thinking more than two decades before he fleshed out his ideas in his groundbreaking On the Origin of Species.
In at least one way, the date of the library's announcement was a natural selection: Darwin's seminal work was published , to the day, before Cambridge released its appeal for help Tuesday.
Why did it take so long for the library to report the notebooks missing? Though a number of searches had turned up nothing as to their whereabouts, the prevailing assumption among Gardner's predecessors was that the notebooks simply had been "misfiled," the librarian .
The library said the notebooks were last seen in the fall of 2000 when they were taken out of the room "where the rarest and most valuable items are kept" for a photography session. But they were not found during a "routine check" conducted in January 2001.
The two notebooks were contained in a small box "about the size of a paperback book," according to the library.
Several investigations followed, but it was only after the failure of a comprehensive search of the Darwin archive's 189 boxes this year that the library came to a different 鈥� and altogether more sinister 鈥� conclusion: "They have likely been stolen."
If there is a silver lining here, it is this: Before the disappearance of their physical manuscripts, both notebooks were digitized 鈥� and they are available for anyone to peruse online currently and .
If you happen to have any information regarding these notebooks' whereabouts, the local police are accepting tips , and the library welcomes further information via email.
