1. A method for sequencing nucleic acid sequences and identifying subsets of nucleic acid sequences, each subset of nucleic acid sequences isolated from a different source, the method comprising the steps of:
- (a) providing at least two different samples of randomly fragmented double stranded nucleic acid targets, wherein each of the randomly fragmented double stranded nucleic acid targets is isolated from a different source;
(b) ligating a sample specific tagged adaptor to each end of each target fragment of each sample to generate adaptor-target-adaptors, wherein the tagged adaptor comprises at least one region of single stranded nucleic acid and a region of double stranded nucleic acid comprising a sample specific tag sequence that differentiates adaptor-target-adaptors originating from different samples, and wherein the sample specific tag sequence is attached directly to the target fragment in each adaptor-target-adaptor with no intervening nucleotides;
(c) amplifying the adaptor-target-adaptors of each sample with a pair of amplification primers complementary to the sample specific tag sequence to generate amplified adaptor-target-adaptors from each sample;
(d) pooling the amplified adaptor-target-adaptors of the at least two different samples;
(e) immobilizing the pooled adaptor-target-adaptors on a surface;
(f) sequencing the immobilized adaptor-target-adaptors on the surface to determine a sequence read of each immobilised adaptor-target-adaptor and identify the sample specific tag sequence of each immobilised adaptor-target-adaptor, thereby determining nucleic acid sequences of the immobilized adaptor-target-adaptors and identifying each of the immobilized adaptor-target-adaptors as a member of a subset of nucleic acid sequences.

Abstract
The invention relates to methods for indexing samples during the sequencing of polynucleotide templates, resulting in the attachment of tags specific to the source of each nucleic acid sample such that after a sequencing run, both the source and sequence of each polynucleotide can be determined. Thus, the present invention pertains to analysis of complex genomes (e.g., human genomes), as well as multiplexing less complex genomes, such as those of bacteria, viruses, mitochondria, and the like.
