Notice to Librarians and Indexers
The Geological Survey's twice-yearly Current Research series
contains many reports comparable in scope and subject matter to thos =
appearing in scientific journals and other serials. All contributions lo
Current Research include an abstract and bibliographic citation. It is
hoped that these will assist you in cataloguing and indexing these reports
and that this wil1 result in a still wider dissemination of the results of the
Geological Survey's research activities.
Avis aux bibliothécaires et préparateurs d'index
La série Recherches en cours de la Commission géologique paraît
deux fois par année; elle contient plusieurs rapports dont la portée et la
nature sont comparables à ceux qui paraissent dans les revues scientifiques
et autres périodiques. Tous les articles publiés dans les Recherchps en
cours sont accompagnés d'un résumé et d'une bibliographie, ce qui vous
permettra, nous l'espérons, de cataloguer et d'indexé-- ces rapports, d'où
une meilleure diffusion des résultats de recherche de la Commission
géologique.
