This article was written for the IIPC-sponsored workshop How to fit in? Integrating a web archiving program in your organisation, held at the Bibliothèque nationale de France, Paris from 26th to 30th November 2012. The workshop was intended to deal with organisational issues such as advocacy, strategy and communication, based mainly on experiences at the BnF, with contributions from other institutions. The article was co-written by two digital curators and a crawl engineer, representing the fact that web archiving activity at the BnF is divided between the Legal Deposit and IT departments. The aim of this article is to present the complete web harvesting workflow at the BnF, with the different tools that are used at each stage and the different profiles of the staff involved.
