Why is this captcha needed? Very uncomfortable. 
Answer Charts:
Without captcha, it is very inconvenient for a webmaster. You have to spend a lot of time deleting spam.

I am a resident of the city of Kaluga in Russia, while walking around the city I found a flash drive, and when I studied its contents on a PC, I found photos and articles from your site there! I decided to see if this site exists, and it turned out that this site exists, and this site is yours! I would like to know how this flash drive got thrown away or lost in Russia when the site is Ukrainian?

Photos or articles from any site can be downloaded and written to a USB flash drive. :)

Very voluminous library, "to dig not to dig". With pleasure they dive into this "abyss" and each time I find what I was looking for and not infrequently something new.

One of the best libraries I've come across. I use 4 years.

Your site is a great tutorial for creative people. On tube equipment, the most complete material in comparison with other sites. Seems like you don't need more. Thanks for the noble work!!!   

Feedback left Bushev Roman Mikhailovich, Murmansk
The site is a real storehouse of technical literature, however, firstly, most of the links are not working. Hopefully the administration will fix it. Secondly, it would be better to upload books not to depositfiles and other file hosting services with download limits, but to clouds or give direct links to ftp servers.

Hello! Thanks for such a great site!
Log search does not work correctly. Maximum 10 results. Those. you type a request, go through ReCaptcha, click "Search", it gives you the first ten results and links to the rest of the search result pages. When we click on next. page, it loads already without search results (although you can see in the address bar), recaptcha again and all over again.
