# RXS_addLibLE()

More often than not, your data files and business logic programs are not going to reside in the same library as your web service programs. RXS_addLibLE() allows you to easily add additional libraries to your library list.

You can use [RXS_libLEExists()](https://isupport.katointegrations.com/rxs/2.x/rxs_libleexists.md) to see if a library list entry exists before adding the library to your library list:
