"They spent 26 minutes in the building committing the burglary but only took a very small amount of books," said General Manager Josh Laffar in a press release sent to Mashable. "They therefore knew what to take but didn't know where it was."

"We are a small business and these books were essentially our companies savings account. These are the only books we had of this value and this will affect all of staff."

"These books are very rare and in some cases unique and not the sort of thing you see every day," said PC Gideon Weigelt-Holmes of the Norfolk police in a statement. "I am urging people, especially book dealers or those working in specialist book shops to be vigilant in case they are offered for sale."

So if you spot any super-valuable first editions pop up on eBay, maybe give Norfolk police a ring.

Anyone with information should contact PC Weigelt-Holmes at Thetford Police Station on 101.

Alternatively contact Crimestoppers anonymously on 0800 555 111.
