why need additional library implemented in msvcp90d.dll?

I have not found any formal document mentioning what is the function of msvcp90d.dll

Multithreaded, dynamic link (import library for MSVCR90.DLL). Be aware that if you use the Standard C++ Library, 
your program will need MSVCP90.DLL to run.

The article indicates STL functinos are exported by msvcp90d.dll
