Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid a direct translation that implies a 'library of extensions' (like software). The key is that the 'service' is 'extended', not the 'library'. A phrase like 'библиотечное обслуживание с выездом' or 'выездная библиотечная служба' is closer.
Common Mistakes
- Using 'extended library service' (less idiomatic).
- Confusing it with 'library extension' which can refer to a physical addition to a building.
- Treating it as three separate words without the compound noun meaning.
