Gentlemen, but it is possible that they have precisely technological reasons. Probably they are improving the information and reference apparatus in connection with the change in the classification feature, for example, nominal to chronological or alphabetical. This is the TECHNOLOGY of the library as an archive.
And in connection with the rearrangements and closed.
In St. Petersburg (!) Metro (!) several times a sign at a closed ticket office was thrown into the eyes: "Technological break". It hurt my eyes every time I ran into them, and I ran them many times. The error is undoubted, but, apparently, very common.
It's very simple: if the problems are related to technology - technical, and if with technology (well, you never know) - technological. It is unlikely that the library has any problems with TECHNOLOGIES, so most likely it was just wrong there.
