The Statistical Seismology Library (SSLib) is:

- a collection of earthquake hypocentral catalogues with space-time-magnitude variables set out in the same format,
- software that can be used to subset and manipulate the catalogues,
- software that can be used to perform
*Exploratory Data Analyses (EDA)*, and - software that can be used to fit stochastic models, in particular,
*Point Process Models*and*Hidden Markov Models*.

The software is written in the R Language, and consists of a number of R packages. Each package has its own Reference Manual that contains documentation for all functions within that package. The software has been developed in the UNIX and Linux operating systems though versions compatible with the Microsoft Windows operating system are also available.

The software has a GPL (≥2) Licence and the intention is to write it in such a way that it can be modified and extended by the user if required.

Please cite the relevant SSLib packages and *Base R Software* when used to produce published works. This software is partially funded by employers and research grants. It is easier to justify such time if one can show that the software is being utilised by others.

An appropriate citation can be generated by entering `citation("PackageName")`

at the R command prompt, for example for package PtProcess, enter `citation("PtProcess")`

. A citation for the *Base R Software* can be generated by entering `citation()`

at the R command prompt.
