This is the complete text of the Welsh-language version of the Book of Mormon published by John Davis in 1852, in parallel with the English (2nd European) edition of 1849, from which the Welsh Book of Mormon was translated. Due to the age of these publications, the content is now in public domain and may be used without restriction.

Available soon! A side-by-side Welsh (1852) and English (2013) Book of Mormon with English chapter headings will soon be available both as a PDF file here and in print from Amazon. We're just waiting for details of the copyright agreement to be completed. (Footnotes have been added to indicate where the 1849 English version and hence the Welsh version differ from the current Book of Mormon.)
The current version of the Book of Mormon in English is available online at https://www.churchofjesuschrist.org . The online version includes chapter headings, cross references and study aids.
The original versions of the 1852 Welsh edition and the 1849 Liverpool edition of the Book of Mormon are available at the links shown below. Note that these versions are not divided into verses and the chapters do not correspond to the current chapters. By copying lines of text in the pdf files, you can obtain a transcription of the text, but the transcriptions, particularly of the Welsh version, have many errors.

A Welsh/English bilingual Book of Mormon is available in a Kindle version from Amazon.com. It is divided into modern chapters and verses. The English version is the current version, which differs from the 1849 Liverpool version primarily in punctuation; however, there are a few places where there are significant changes. The downsides to the Kindle version include the limitations in resizing the text, the difficulty in printing the document, the fairly large number of transcription errors, the difficulty in navigating the document, and the limitations in copying the text.
