• Betina Giordano, graphic designer at Santiago, Chile, designed the cover of the book.
• Heikki Hyyrö, PhD. student at University of Tampere, Finland, gave us an excellent explanation of Myers' bit-parallel algorithm and authorized us to write Section 6.4.2 based on his manuscripts. He also found the improvement of Section 4.5 mentioned in the "extra material and comments" section.
• Manuel Ortega, undergraduate student at University of Chile, Chile, carefully checked the book, especially the algorithms and examples, and found tens of errors before the book appeared.
• Alvaro Herrera, undergraduate student at University of Chile, Chile, found some small mistakes before the book appeared.
• Michiel Frishert, MSc. student at University of Technology Eindhoven, The Netherlands, found an error in page 114.
• Rodrigo González, PhD. student at University of Chile, Chile, found some small mistakes in pages 26, 33 and 58.
• Lucian Ilie, University of Western Ontario, Canada, found several errors in pages 25, 31, 56, 84, 90, 92, 128, 157-158, 159, 160 and 172. He also pointed out an update in page 139.
• Karina Figueroa, PhD. student at University of Chile, Chile, found small errors in pages 69 and 120.
• Diego Arroyuelo, PhD. student at University of Chile, Chile, found some small mistakes in pages 18, 50 and 105.
• Aki Hasegawa, Bioinformatics Group, Genomic Sciences Center (GSC), RIKEN, Japan, found several mistakes in pages 53, 54, 72, 89, 110 and 116.
• Fabiano Cupertino Botelho, a PhD. student at Universidade Federal de Minas Gerais, Brazil, and his advisor Nivio Ziviani, found an error in page 153. Actually Heikki Hyyrö had pointed out the error long before, but for some reason I forgot to add it to the erratas. It is interesting that this error has propagated for long time in many papers of approximate string matching.
• Liu Ping, Chinese Academy of Sciences, pointed out an error and possible improvements in the pseudocode of page 71.
• Piti Piyachon, a student at University of Massachusetts Lowell, noticed it is not said that the parser in page 140 needs fully parenthesized expressions.
• Pierre Vanmosnenck, Belgium, found the mistakes in pages 21 and 119.
• Joaquín Adiego, from Universidad de Valladolid, Spain, communicated the error on the argument in page 64.
