The [bot](https://t.me/libgen_scihub_2_bot) allows you to access the whole Sci-Hub and LibGen libraries through Telegram.
It has a full-text morphology search, search by DOIs, allows to get references and do orderings by dates and citations. Some part of papers is indexed by not only abstracts but content too. Moreover, I’ve deployed crawling Telegram channels/groups recently and already acquired more than 70000 scientific papers (mostly in medicine and biology) of 2022 year that are absent in Sci-Hub.
Free science must go on.
