A pair of asymmetrical, partially double-stranded oligonucleotide adapters are provided wherein the pair of adapters comprise a first asymmetrical oligonucleotide adapter comprising a single-stranded 3* overhang and a second asymmetrical double-stranded oligonucleotide adapter comprising a single-stranded 5' overhang and at least one blocking group on the strand of said second asymmetrical oligonucleotide adapter that does not comprise the 51 overhang. Also provided are a pair of double-stranded Y oligonucleotide adapters and a pair of double-stranded bubble oligonucleotide adapters and methods of using said asymmetrical adapters for amplification of at least one double stranded nucleic acid molecule, wherein the amplification produces a plurality of amplified nucleic acid molecules having a different nucleic acid sequence at each end are also described. Also provided is a method for exponentially amplifying one strand in a double- stranded nucleic acid molecule. Also provided are methods for preparing libraries of paired tags using COS-linkers. Also provided are cleavable adapters comprising an affinity tag and a cleavable linkage, wherein cleaving the cleavable linkage produces two complementary ends. Methods of using the cleavable adapters to produce a paired tag library are also described.
