ISO 2146 is an ISO standard defining an information model for "registry services for libraries and related organizations". Operating at a higher level than item-level standards such as MARC, it takes as principal elements parties (people or organisations), collections (of books, data, etc.), services and activities (grants, projects, etc.)

The first edition of ISO 2146 was published in 1972 as "Directories of libraries, information and documentation centres"; the second edition was published in 1988. The third edition was initially driven by the need to support interlibrary loan services online, but it has been broadened in scope to encompass

The third edition reached publication stage in March 2010.

Thiago Martins (born 4 September 1976 in São Paulo, Brazil) is a retired Brazilian football striker who played professionally in the United States and Norway.

Martins was born on the east side of São Paulo, Brazil, and came to the United States in 1996. He landed in Los Angeles, California, at 19 years old and with little money. He eventually made his way to Santa Barbara, California, where he slept in hotels until his money ran out. He had to resort to sleeping on the beach. Fortunately he awoke one morning to a group of people playing soccer on the beach and joined them. One of the players took Martins into their home, even though Martins spoke little English or Spanish and they spoke no Portuguese. He began to play soccer in Sunday leagues, where Tim Vom Steeg noticed his skill as he attempted to defend him in one game.

"He was up top and I was a defender, so I covered him. I've covered a lot of forwards, Eric Wynalda for example, but no one was as strong as Thiago. He was just so powerful. When the game ended we talked, and I asked him if he was interested in playing at City College and getting an education." - Tim Vom Steeg
