One of its chief appeals, and the reason why I sought to access the site in the first place, is a Database of Verbal Aspects, which has to offer, besides a table of Russian aspectual pairs, analyses of Russian verbs ("Pairing Productivity", "Aspectual Productivity", "Morphological Structure")
A screenshot of a table of Russian aspectual pairs generated by / extracted from the site (Borrik & Jansen, 2012)
Unfortunately the site would go down on an SQL error 1049 once you try to access the sole link in the page or try to search for an entry through search box. I've tried accessing records of the site in Archive; it seems that the link to the Database of Verbal Aspects seems to be up and going as late as 2020:
https://web.archive.org/web/20120226131 ... ion=aspect
though clicking on the links on said page, yet again, lead to no results. Any way to access the database that the links on said page leads to? Or perhaps there are alternatives which I am yet to be aware of?
