The present disclosure generally relates to nucleic acid amplification systems and methods suitable for construction of nucleic acid samples, including construction of normalized nucleic acid libraries. In some embodiments, the method includes providing one or more input nucleic acid samples, contacting each of the input nucleic acid samples (e.g., input library) with a reaction mixture including first amplification or normalization primers and second amplification or normalization primers, wherein the first amplification or normalization primers are immobilized on a solid support and the second amplification or normalization primers are in solution phase, and amplifying the input nucleic acid samples under conditions such that substantially all of the first amplification or normalization primers are incorporated into amplification products. Further provided are systems and droplet actuator devices that are configured to carry out the methods disclosed herein. Compositions that include nucleic acid samples and libraries, preferably normalized, prepared in accordance with the disclosed methods and systems are also provided.
