Overview of LIGO scientific collaboration inspiral searches

We describe the effort of inspiral searches with LIGO data from the third and fourth science runs, which took place in 2003/2004 and 2005, respectively. Although the analysis pipeline is the same for all searches, there are significant differences between the three major ongoing searches: for primordial black hole binaries, binary neutron stars and binary black holes. The horizon distance for all searches significantly increased with respect to earlier LIGO science searches.
