In Roger, to broaden your searches and improve retrieval, use truncation, by adding the "*" wildcard symbol: e.g. ecolog* (with the * at the end) to search on multiple ecology-related terms: ecology, ecological, etc. Similarly, use biodivers* (with the *) to search on multiple biodiversity-related terms: biodiverse, biodiversity, etc.
Warning: use these terms (biodivers* ecolog* conserv* pollut*), or any broad truncated term (i.e. using the "*" wildcard on common words) WITH your specific subject terms, because used alone in a search they will retrieve very general and large results.
For example: reef ecolog*; fish biodivers*; reef conserv*; ocean pollut*; marine microb* environ*; etc.
If you don't have an author or title, start with the keyword search.
Searching ocean pollution plastic* is the same as ocean and pollution and plastic* , and will retrieve only records with all terms.
Searching biodiversity or diversity will retrieve results with at least one term, giving you a larger set of results.
Use the Roger Request feature (link at the top of the screen) to request that books be delivered to SIO for you (this service is restricted to Scripps graduate students, faculty & staff).
If you see >> Go to electronic version in the record, most of these are links to get to an online e-book.
