In the old days, LCCNs were "card numbers". When the machines came, they got upgraded to "control numbers". When Linked Data came around, they got upgraded to "concept numbers". <id.loc.gov/authorities/names/n88055112> identifies a concept. Likewise, <http://www.worldcat.org/oclc/136259> identifies a book. String identifiers are buggy whips.
