Sixty-eight teams is plenty to keep track of, so here is a simple guide to remind you which teams have earned automatic berths to the 2014 NCAA tournament.
Ivy League: Harvard (26-4, 13-1 in conference)
How did they get there? The Crimson defeated Yale 70-58 on March 7 to secure their Ivy League title. The Ivy League does not have a conference tournament, which helped Harvard become the first team to clinch a tournament berth.
NCAA tournament history: This is Harvard's third consecutive appearance in the tournament after a 66-year absence. Last year, the Crimson logged one of the most notable second-round upsets by beating third-seeded New Mexico, 68-62.
Big South: Coastal Carolina (21-12, 12-5 in conference)
How did they get there? The Chanticleers defeated arch-rival Winthrop 76-61 in the Big South title game. Coastal Carolina had lost its last three conference championship appearances to UNC-Asheville in 2011, and then Winthrop in both 2006 and 2010.
NCAA tournament history: Coastal Carolina has not been to the NCAA tournament since 1993 and has lost its only two tourney games. Head coach Cliff Ellis guided three other schools -- South Alabama, Clemson and Auburn -- to the tournament in his 36 years as a head coach. Ellis' last tournament appearance was in 2002-2003, when he led Auburn to the Sweet 16.
Ohio Valley: Eastern Kentucky (24-9, 13-5 in conference)
How did they get there? The Colonels beat established OVC power Belmont, 79-73. They are anchored by a dynamic backcourt of guards Glenn Cosey and Corey Walden, who average about 32 points per game between them.
NCAA tournament history: Eastern Kentucky has not been to the tournament since 2007, when it lost to top-seeded North Carolina, 86-65. The Colonels lost to state rival Kentucky, 72-64, in the 2005 tournament, which was their first tourney appearance in 26 years.
Atlantic Sun: Mercer (26-8, 14-4 in conference)
How did they get there? The Bears outlasted last year's NCAA tournament darling, Florida Gulf Coast, 68-60 on the road. The Bears withstood "Dunk City" with strong interior defense and clutch shooting down the stretch.
NCAA tournament history: Mercer is making its third tournament appearance and its first since 1985. The other tourney trip happened in 1981. The Bears lost in the first round both times.
Missouri Valley: Wichita State (34-0, 18-0 in conference)
How did they get there? The Shockers beat Indiana State 83-69 in the Missouri Valley Conference title game to finish a perfect regular season and become just the second team ever to start a season 34-0. All indications are Wichita State will be No. 1 seed once the brackets are announced.
NCAA tournament history: This year is Wichita State's third straight season in the NCAA tournament and 11th overall. The Shockers made it all the way to the Final Four last season, but lost to eventual national champion Louisville in the national semifinals.
Colonial Athletic Association: Delaware (25-9, 14-2 in conference)
How did they get there? The Blue Hens broke the hearts of William & Mary, 75-74, in a game where Delaware trailed by six points with only 1:20 remaining. Down 74-68, Delaware scored the final seven points of the game to deny the Tribe their first-ever NCAA tournament appearance.
NCAA tournament history: The Blue Hens' last appearance was a 62-52 loss to Tennessee in 1999. Delaware is 0-4 in the tournament all-time.
Metro Atlantic Athletic Conference: Manhattan (25-7, 15-5 in conference)
How did they get there? The Jaspers defeated rival Iona, 71-68, in a taut MAAC final. Manhattan receives most of its scoring from guard George Beamon, who scored 16 points in the tournament final and entered the game averaging 19.4 per contest.
NCAA tournament history: This is the Jaspers' first tournament appearance since 2004, when they upset fifth-ranked Florida in the first round and narrowly lost to Wake Forest in the round of 32. Manhattan is 3-7 all-time in the NCAA tournament.
Southern Conference: Wofford (20-12, 11-5 in conference)
NCAA tournament history: The Terriers are making their third NCAA tournament appearance ever, all of which have come in the last five seasons. They still have yet to win a game in the tournament after losing to Wisconsin in 2010 and BYU in 2011.
Northeast Conference: Mount St. Mary's (16-16, 9-7 in conference)
How did they get there? The Mountaineers toppled top-seeded Robert Morris, 88-71, with a barrage of made shots in the first half. Robert Morris was never able to recover, and second-year coach Jamion Christian (age 31!) has his team in the NCAA tournament.
NCAA tournament history: This is the fourth NCAA tournament appearance for Mount St. Mary's and its first since 2008, when they won a play-in game against Coppin State before losing to UNC in the round of 64.
Horizon League: Milwaukee (21-13, 7-9 in conference)
How did they get there? The Panthers won four games in their conference tournament, beating Detroit and Valpo before knocking off Green Bay to get into Horizon final. Hot shooting from deep kept Wright State from being able to play its game, and Milwaukee captured the auto bid with a 69-63 win.
NCAA tournament history: The Panthers are making their fourth appearance in the NCAA Tournament. The most memorable run for Milwaukee was 2005, when it made the Sweet Sixteen after beating Alabama and Boston College. It eventually fell to Illinois, 77-63, as the Illini would go on to play in the NCAA Championship against UNC.
Summit League: North Dakota State (25-6, 12-2 in conference)
How did they get there? Despite a poor shooting night, Summit League Player of the Year Taylor Braun got an and-one with 12 seconds to play to put the Bison up four and steal a 60-57 win away from IPFW in the conference championship.
NCAA tournament history: North Dakota State will be enjoying its second NCAA tournament appearance, with the other coming in 2009. The Bison gave Kansas a run in their one and only game, losing 84-74.
West Coast Conference: Gonzaga (28-6, 15-3 in conference)
How did they get there? The Bulldogs jumped out to a 44-27 lead at the break against BYU, but weren't able to put the Cougars away easily as Gonzaga only hit 19-of-30 free throws and missed some costly one-and-ones. Sam Dower had 20 points and 13 rebounds in the win.
NCAA tournament history? Gonzaga has been in the tournament approximately a million times since Mark Few became head coach. The Bulldogs have been to five Sweet Sixteens and one Elite Eight (in 1999).
Patriot League: American University (20-12, 13-5 in conference)
How did they get there? The Eagles defeated Boston University in the Patriot League championship game. Despite Boston having home-floor advantage, American was able to hold the Terriers to 30.8 shooting for the floor in a 55-36 win.NCAA tournament history?
