  Requirements quality literature abounds with publications presenting
artifacts, such as data sets and tools. However, recent systematic studies show
that more than 80% of these artifacts have become unavailable or were never
made public, limiting reproducibility and reusability. In this work, we report
on an attempt to recover those artifacts. To that end, we requested
corresponding authors of unavailable artifacts to recover and disclose them
according to open science principles. Our results, based on 19 answers from 35
authors (54% response rate), include an assessment of the availability of
requirements quality artifacts and a breakdown of authors' reasons for their
continued unavailability. Overall, we improved the availability of seven data
sets and seven implementations.
