The present invention relates to methods for producing solid supports. The present invention further provides a mixture of said solid supports for tagmentation of target DNA for DNA sequencing approaches, a corresponding kit comprising the same and methods employing said mixture of solid supports and/or kit. Specifically, methods for producing sequencing libraries and corresponding DNA sequencing methods for analyzing the generated sequencing libraries and tools used therein are provided. In particular, DNA sequencing approaches allowing preservation of contiguity information of long DNA fragments even when using short read sequencing approaches are disclosed. A key concept of the present invention is to employ segmented barcodes, with every barcode segmented allowing for barcode error detection and correction on a segment level. Preferred barcode sequences employed are characterized in that they comprise no linker sequences or only linker sequences of one or two nucleotides in length between the barcode segments.
