I am trying to do my CV and would like to build bibliography using Biblatex. In the CV, I have different sections to list my published books, and journal articles, while in each section I want to sort all items by year starting from the most recent.

I was able to sort the entries by year descending following the answer of @moewe: https://tex.stackexchange.com/a/434393/173148. However, when printing bibliography by sections, the years of all publication were shown instead of only the years for the current section.

The code I used to produce this result: documentclass{article}
usepackage[style=authoryear,sorting=ydnt]{biblatex}
usepackage{filecontents}

begin{filecontents}{jobname.bib}

@book{book1,

  author = {author1},

  date = {1862},

  title = {Book1},

}

@book{book2,

  author = {author1 and author2},

  date = {1831},

  title = {Book2},

}

@article{article1,

  title={title1},

  author={author1 and author2},

  journal={journal1},

  volume={1},

  number={1},

  pages={1},

  year={1841}

}

@article{article2,

  title={title2},

  author={author2},

  journal={journal2},

  volume={2},

  number={2},

  pages={2},

  year={1842}

}

end{filecontents}
