To locate books on your topic, use the UC Library Search. As a starting point, use a keyword search on the likely terms. For collections of data, add handbooks or tables to your keywords.
If you find a relevant record, check its subject headings to see if there is alternative terminology you should try. Similarly, use keyword searches to find books on particular analytical methods (mass spectrometry, atomic absorption). You may also want to browse in the book stacks. Useful call nubmer ranges include:
Landolt-Börnstein (QC 61 .L3)
This large set of data tables for physics and chemistry has been
published over the past 90+ years. UCSB owns a partial print set (see
the call number above), but the set from 1918-2009 is available online to
UCSB users. The series is divided into broad groupings as follows:
At present, our print copy is in off-campus storage. The online archive may be browsed by the title of individual volumes; there is currently no full-text searching of the online archive.
