Google Books cataloguing
It’s great that so many books and journals are being scanned and put online, and mistakes are unsurprising given the pace. Going through Google’s collection of Библиотека для чтения, I’ve so far found that at least volumes 3, 10, 11, 23, and 28 are in the wrong place. Two from 1835 are filed under 1853, and several from 183x were classified (by a person or a computer?) under 185x. They do have a place where errors can be reported, and I’m trying to mention them as I see them. These are cases where the title and volume are correct, and the system could match them to other issues of the same serial – I wonder how many have a more serious problem and aren’t easily found by searches, even if they have been scanned?
