RT Journal A1 Miksanek T T1 Hidden treasure: The national library of medicine JF JAMA JO JAMA YR 2012 FD August 8 VO 308 IS 6 SP 625 OP 626 DO 10.1001/jama.308.6.625 UL http://dx.doi.org/10.1001/jama.308.6.625 AB Although perhaps more associated with its Internet services and online publications such as PubMed, ClinicalTrials.gov,the Visible Human Project, and MedlinePlus, the NLM contains a collection of items from all over the world, dating back to the 11th century. Many of these objects are treasures in the truest sense of the word; others have historical and cultural significance. Some are simply quaint or outlandish. Hidden Treasure is a sampling of NLM “stuff ” that sometimes defies written description.
