free (and most of the time) open source software - most basic software .small[ ### Zotero - free and open source (FOSS) citation manager - integrates well in browser and Office Software ### Libre Office - FOSS office package - most commands and procedures similar to 'the other' office package ### OxCal - free, but not open source - quasi standard in archaeology ### QGIS - FOSS GIS package - General ideas and concepts are transferable to 'the other' GIS software ] --- ## Prerequisite for successful participation - a laptop (if you do not own one, we can provide you) - endurance - curiosity - installing some software And in the end a test, consisting of a theoretical and a practical part Test will be written after the semester. --- ## ToDo till next meeting - Install Libre Office (https://de.libreoffice.org/) - Install Zotero (https://www.zotero.org/) - (optional) install Zotero Connector (https://www.zotero.org/download/connectors) --- class: inverse, middle, center # Any questions? .footnote[ .right[ .tiny[ You might find the course material (including the presentations) at https://berncodalab.github.io/caa You can contact me at <a href="mailto:martin.hinz@iaw.unibe.ch">martin.hinz@iaw.unibe.ch</a> ] ] ]
