Problem: The Dewey Decimal Classification (DDC), or Dewey Decimal System, is a proprietary library classification system first published in the United States by Melvil Dewey in 1876. It has been revised and expanded through 23 major editions, the latest issued in 2011, and has grown from a four-page pamphlet in 1876. It is also available in an abridged version suitable for smaller libraries. It is currently maintained by the Online Computer Library Center (OCLC), a non-profit cooperative that serves libraries. OCLC licenses access to an online version for catalogers called "WebDewey". 

The Decimal Classification introduced the concepts of "relative location" and "relative index" which allow new books to be added to a library in their appropriate location based on subject. Libraries previously had given books permanent shelf locations that were related to the order of acquisition rather than topic. The classification's notation makes use of three-digit Arabic numerals for main classes, with fractional decimals allowing expansion for further detail. Using Arabic numerals for symbols, it is flexible to the degree that numbers can be expanded in linear fashion to cover special aspects of general subjects. A library assigns a classification number that unambiguously locates a particular volume in a position relative to other books in the library, on the basis of its subject. The number makes it possible to find any book and to return it to its proper place on the library shelves. The classification system is used in 200,000 libraries in at least 135 countries.

Problem: (CNN) -- Floyd Mayweather Jr. has said he is ready to make the big-money fight with newly crowned WBO welterweight world champion Manny Pacquiao happen. 

After victory in Las Vegas over Puerto Rico's Miguel Cotto on Saturday, Pacquiao's trainer Freddie Roach said the "whole world" now wanted to see a fight with Mayweather. 

Reacting to the proposition the undefeated 32-year-old, who formerly held the WBC title at welterweight, told British broadcaster Sky Sports: "If he wants to fight Floyd Mayweather all he has to do is step up to the plate." 

The twice-voted Ring magazine fighter of the year added that he felt Pacquiao's approach was one-dimensional but the Filipino would be a favorite with the crowd. 

"The thing is with Pacquaio I don't see any versatility as a fighter; he's a good puncher but just one-dimensional. Is Pacquiao the greatest? 

"The world's going to go 'wow' if Floyd Mayweather gets beaten. That's what everyone is looking to see. 

"If I beat Manny Pacquaio do you know what they are going to say? 'You are supposed to beat him, you are Floyd Mayweather, you are the bigger man'. If I knock him out they'll say 'you're supposed to knock him out he's been knocked out before'. 

"I'm in a no-win situation and when I beat him no one is going to be surprised because he's been beaten before; whatever I do to Pacquaio has been done before - he's been beaten on three occasions. And if I knock him out I don't want the world shouting because he's been knocked out twice before."

Problem: Beloved teacher Michael Landsberry, a former Marine, died a hero at Sparks Middle School in Nevada on Monday in another tragic campus shooting. 

The 45-year-old was killed while trying to talk to the unidentified 12-year-old gunman, who later killed himself. 

"He was telling him to stop and put the gun down," student Jose Cazares told Today on Tuesday. "Then the kid, he yelled out, 'No!' Like, he was yelling at him, and he shot him. The teacher was calm, he was holding out his hand like, 'Put the gun in my hand.' " 

Students, parents and fellow teachers are calling Landsberry's actions heroic. Tom Robinson, vice chief with the Reno Police Department, also praised him, saying, "In my estimation, he is a hero. We do know he was trying to intervene (,)." 

Landsberry, who went by the nickname Batman, and coached sports teams at the middle school and neighboring high school, was remembered fondly on social media by many students. 

"It's just so sad knowing he left because he protected his students," one of the posts said, followed by another that read, "The sad part is this week it's his and his wife's anniversary and his daughter graduates from the military tomorrow." 

CNN reports that two students who were wounded by the shooter - who used a Ruger 9 mm semi-automatic handgun - are currently in stable condition in hospital. 

Authorities will not be releasing the identity of the shooter out of respect for his parents, but schoolmate Amaya Newton was shocked by his actions, calling the gunman "a really nice kid," adding, "He would make you smile when you were having a bad day." 

"Everybody wants to know why the shooter opened fire," Sparks vice chief Tom Miller said at a news conference. "That's the big question. The answer is we don't know right now, but we are trying to determine why."
