Searching the newsletters
Newsletters are compiled in individual PDF volumes for each year back to 1935. The PDF for each year can be searched using the Find command within the PDF reader. There are two ways to search the whole collection:
1. Use Google Search box above.
2. Use the Cumulative Newsletter Index — this is a large PDF containing a set of indexes curated by newsletter editors every few years since 1939. Each index is itself organized variously by subject, author, society business, field trips, etc. Entries in the index are not linked directly to the newsletters themselves. As a result you may have to hunt around a bit to figure out which index containing references to a particular search term relates to what year and then backtrack to the that year's PDF and search again for the search term there.
