Mobile Library Pt.1

Every three weeks the mobile library is coming comes to our village. The mobile library comes in a particularly for books converted bus bus that has been converted for books. When the bus halts and the visitors boarding the bus the driver and librarian turns his seat. By doing this, he sits behind the counter. On both sites sides of the bus are shelves with books on them. On one site side are boxes. The boxes containing children´s books, board games, film DVDs, music CDs and audio books. The console games are under the control of the librarian after behind the counter. Within the village's width of one km the bus stops three times.
Children, pupils and students pay no fees for lending borrowing. A single adult pays 18 €, a family card costs 25 € per year, but it is possible to pay per month if you like prefer it or need to do so. 

After boarding, the previously lent borrowed medias are returned, the loan period of not unfinished books will be extended if possible and new medias are requested.

"film DVDS" would usually be called "DVDs" (no need for film)

Auf Deutsch: "film DVDS" werden gewöhnlich als "DVDs" ("film" ist nicht erforderlich)

Robingrindrods translaten is good but I felt it missed a couple of mistakes / ambiguities. Good work, if you want me to explain anything I've said on either of your corrections feel free to message me.

Mobile Library Pt.2

The last thing is most important. You can request nearly every any book (inclusive including foreign-language books and comics), audio books, music, films or games that you want. The Mobile Library is an organisation and part of a greater union of libraries (nearly almost all) in Germany. In 90% of the cases you will get what you want in three weeks. In the few other cases you have to wait longer.
Due to this the books in the bus are merely a decoration. You look at them during the wait and the children are occupied.
The supply in the countryside is much better than in the city. There is also a public library in every town. In a larger city, every quarter has a lending public library. These branch libraries are, however, only usually opened usually only for a few hours per week and most of the interested people get there by public transportation. But you can sit and read when it's cold outside, or if you prefer newspapers on paper.

Note: Verein I have taken to mean organisation as this fits best. My German isn't good enough to know for sure though.

Rough translation to German, apologies for the mistakes, it may be easier to understand:

Auf Deutsch (annähernd):

(Verein habe ich unternommen um "organisation" auf English bedeuten. Dies macht den meisten Sinn für mich, aber mein Deutsch ist nicht gut genug um sicher zu sein.)
