Canadian government information can be difficult to find. Here are some tips.
Anyone interested in cold-water species will probably find the WAVES catalog useful.
The WAVES database is the online catalog of the libraries of Fisheries and Oceans Canada. The Canadians have done a lot of work digitizing their publications, and you can find online versions of most Canadian manuscript reports and Canadian technical reports that have been published in the last few years. They've re-designed their web pages, and you can see at a glance if the publication you want is available online. The "advanced" search is particularly useful, because you can specify author, series, date as well as keywords.
This is also a very useful resource for translations. The issues in the series "Canadian translation of fisheries and aquatic sciences" are listed, and, although almost none of them are available online, this is a most valuable resource for finding translations of Russian, Japanese and other publications. The Guin Library has many, but not all, issues in this series. Try variant spellings for author names, especially for the Russians.
