 - Archive versions of `ready4` code libraries are **permanent copies** of `ready4` code libraries that are stored by Zenodo and accessible through [ready4's Zenodo community page](https://zenodo.org/communities/ready4). Multiple copies of each code library - capturing the evolution of the code at different points in its lifecycle - can be archived, with each copy assigned its own DOI. Archived code is the most appropriate type to cite in peer-reviewed publications. 
 
-A table of the most up to date list of R package extensions to the `ready4` framework can be generated by web-scraping using `make_libraries_tb` (produces up to date results but a little slow) or alternatively downloaded from a periodically updated database using `get_libraries_tb` (quicker to implement, but may miss the most recent additions)

 A HTML version of the table can be printed using `print_packages`. It should be noted that in addition to the information for citing each code library, the documentation for each library consists of a website (normally the first resource that should be visited prior to installing the software) and two versions of a PDF manual (a brief version suitable for most users and a longer version aimed at developers).
