A depleted sequencing library can be prepared by providing a composition comprising a heterogeneous mixture of linear nucleic acids having a first terminus and a second terminus. A first subset of target nucleic acids and a second subset of non-target nucleic acids can include a first adaptor region at the first terminus and a second adaptor region at the second terminus. A third subset of the target nucleic acids and a fourth subset of the non-target nucleic acids include the second adaptor region at the first terminus and at the second terminus. Removable blocker oligonucleotides can be added to the composition, non-target nucleic acids can be removed from the composition by sequence capture to bait oligonucleotides, and the composition can be treated to reduce a quantity of free blocker oligonucleotides that are not annealed to an adaptor sequence or to a sequence substantially complementary to an adaptor sequence.
